Organization Alert: Magnetic Resonance Lab
“Magnetism, as you recall from physics class, is a powerful force that causes certain items to be attracted to refrigerators.” -- Dave Barry (American Writer and Humorist, b.1947)
So many technologies, so little time … Magnetic resonance is one of the technologies being used to explore the desulfurization problem. Accordingly, Montana State University’s Magnetic Resonance Lab (http://www.coe.montana.edu/mrm/) is one of the organizations worth visiting from time to time. Here is some information from its Web …

Ceramics and Foams
These modern materials are invaluable to the alternative energy industry, food industry and medical industry. Our ability to increase the range of application of fuel-cells, or design next generation filtration systems for industry and medicine, depends on our ability to improve our understanding of transport in the complex structures of designed porous media such as new ceramics and foams.
Porous Media
The underlying physics of transport in porous media is relevant to the aforementioned ceramics and foams as well as a plethora of other applications like industrial packed bed chemical reactors, transport in gels and tissues for drug delivery, storage of supercritical CO2 in natural formations and in sub-surface transport of environmental contaminants in the earth’s subsurface. Many porous media of interest have structures that generate complex dynamics which can be modeled by fractal and percolation theory concepts. MR methods provide unique data for scale dependent transport in porous media since most are opaque and not amenable to analysis by other methods. Modeling the impact on transport dynamics of biological and chemical reactions in porous media presents a significant challenge for design of environmental remediation strategies and new materials.

CATALYTIC FUEL REFORMING for FUEL CELL APPLICATIONS
Catalysts are being developed to convert a wide variety of potential fuels into hydrogen, for use in low temperature, Proton Exchange Membrane (PEM) fuel cells. Some of the fuels which have been utilized include ammonia, methanol, propane, as well as gasoline and diesel model hydrocarbons. Current research emphasis is on the stability of reforming catalysts and the development of catalysts and process conditions to improve sulfur tolerance of these catalysts. Funding has been provided by the US Army as well as the National Science Foundation. In addition to investigations of both steam and dry reforming of hydrocarbons, some of the work has also concentrated on CO removal via the water gas shift reaction and preferential oxidation of CO.

Abstract
Hydrodesulfurization (HDS) of low-sulfur model and commercial diesel fuel (500 ppmw S) using Pt/Al2O3 catalysts prepared by supercritical carbon dioxide (scCO2) deposition method is investigated at atmospheric pressure and in temperature range of 290–350 °C. The reactivity of the investigated organosulfur compounds followed the known trend, that is: BT > 2-MDBT > DBT 4-MDBT > 4,6-DMDBT, despite the nonconventional operating conditions and catalyst. The HDS of dibenzothiophenes was found to proceed only via the direct desulfurization route (CS bond scission) under the studied conditions whereas HDS at high H2 pressure proceeds via both direct desulfurization and hydrogenation routes. This limitation had several consequences. Under atmospheric pressure, the HDS reaction exhibited low reactivity particularly towards the stericly hindered substituted dibenzothiophenes. HDS of commercial diesel at atmospheric pressure using catalyst prepared by supercritical fluid deposition technique was found to be feasible, however, the catalyst had to have high metal loading and the reactor had to be operated under high H2/fuel ratio with low hourly space velocity.

Abstract
In situ catalytic upgrading of heavy oil and bitumen has been suggested and tested in the laboratory for utilization of heavy oil resources. Experimental observations have demonstrated potential, so this innovative recovery technique may have a role in the development of large resources of heavy oil and bitumen. Accurate analytical and numerical modelling is necessary in order to correctly interpret experimental measurements of the in situ upgrading, leading to a better understanding and design of field-scale processes. In this paper, we present modelling and parameter estimation for ultra-dispersed catalytic upgrading experiments conducted in a batch reactor. The Monte Carlo simulation technique was used to estimate the most appropriate reaction parameters. The combination of an analytical batch reactor model and the Monte Carlo simulation technique allows for the fast generation of a large number of upgrading experiment realizations. Comparisons of analytical modelling results with the experimental measurements of the upgrading experiments at different temperatures are in close agreement. Results reveal that ultra-dispersed catalytic upgrading in a batch reactor results in a fairly high residue conversion and can potentially increase the API gravity of the produced oil.

Abstract
Asphaltene precipitation plays an important role in both oil production and refining processes. In this paper, asphaltenes are precipitated from a heavy oil sample under different experimental conditions by using three different light alkanes, i.e., propane, n-pentane, and n-heptane. A variety of analytical techniques are applied to characterize the precipitated asphaltenes and deasphalted heavy oil (i.e., maltenes), such as the density and viscosity measurements, vapour-pressure osmometry, freezing-point osmometry, scanning electron microscope (SEM) imaging, nuclear magnetic resonance (NMR) measurement, and simulated distillation for compositional analysis. It is found that the yields and properties of the precipitated asphaltenes and remaining maltenes strongly depend on the specific precipitant tested and the liquid precipitant-to-oil volume ratio used. The asphaltene yield decreases as the carbon number of an alkane increases, while it increases monotonically and finally reaches a plateau if the liquid precipitant-to-oil volume ratio increases up to 20–40 for n-pentane and n-heptane, respectively. As a result, n-heptane-precipitated asphaltenes (C7-asphaltenes) have the highest molecular weight and aromaticity among the three kinds of precipitated asphaltenes. C7-asphaltenes are bright and black particles, whereas n-pentane-precipitated asphaltenes (C5-asphaltenes) are dull and brown powders. Propane-precipitated asphaltenes (C3-asphaltenes) together with some amount of co-precipitated resins are found to be highly viscous and semi-solid like immediately after the flashed-off process but become more and more liquid-like afterward. Compositional analysis results of the original heavy crude oil and three different maltenes indicate that the carbon numbers of most precipitated asphaltenes are higher than C50.

AbstractSulfur breakthrough behaviors during reformate desulfurization were investigated using a novel ZnO-based sorbent with minimized mass transfer resistance. The presence of CO, CO2, or water affected the breakthrough characteristics of H2S and carbonyl sulfide (COS). CO and CO2 did not significantly affect the reaction between H2S and ZnO, but they reacted with H2S to form COS, which cannot be efficiently removed by ZnO. The mechanisms of COS formation via two different pathways were also investigated. CO reacted with H2S to form COS homogeneously; CO2 reacted with H2S heterogeneously on the sulfide surface. COS formation by CO and CO2 was suppressed by H2 and water. Water also severely hindered the reaction between ZnO and H2S and significantly decreased H2S breakthrough time. At low water concentrations, sulfur breakthrough was determined by the homogeneous COS formation; at high water concentrations, it was controlled by H2S breakthrough. Capacity loss due to COS formation and adsorption of water was also observed. Novel sorbent and process designs are required to improve the desulfurization performance.

Abstract
Cerium atoms have been introduced into the framework of MCM-41 by a hydrothermal synthesis method with cetyltrimethylammonium bromide (CTMABr) as template, sodium silicate as silica source, and cerium chloride as cerium source. Desulfurization of various model fuels containing about 500 μg/g sulfur were studied over the synthesized CeMCM-41 with a liquid hourly space velocity of 7.5 hr-1 at ambient conditions. The sulfur adsorption capacity was 10.0, 11.8, 14.0, and 15.4 mg(S)/g adsorbent for thiophene, dibenzothiophene (DBT), 4,6-dimethyldibenzothiophene (4,6-DMDBT), and tetrahydrothiophene (THT), respectively. The charges on S atom in thiophene, DBT, 4,6-DMDBT, and THT, calculated by using density functional theory (DFT), are -0.159, -0.211, -0.214, and -0.298, respectively, implying that the S-M bond between the adsorption sites and thiophene is much weaker than that between the adsorption sites and DBT, 4,6-DMDBT, or THT.

Technology Tip: Deli.cio.us (social bookmarking)
"Why ask why? If it's raining it just is." -- Douglas Horton, American Protestant clergyman (1891-1968)
If you bookmark interesting sites … and who doesn’t … you’ve probably noticed how difficult it is to keep track of them. Even if you organize them into folders, it can be hard to remember exactly where a given bookmark is located when you need it.
Social bookmarking services like Deli.Cio.Us (www.delicious.com) can help.
Why use it? Many reasons. Here are three …
One: tagging. Unlike folders, where you have to pick one folder to describe a site, in Deli.Cio.Us you can use as many tags as you want to describe the site.
Two: describing … A few sentences copied from the site’s “About” page can often help remind you why you bookmarked the site in the first place. Deli.Cio.Us provides a description field that enables you to paste those sentences for future reference
Three: sharing … Share the tags and descriptions of your bookmarks with colleagues by inviting them to join Deli.Cio.Us so they can see your bookmarks. Your reputation as an expert will be enhanced.

Hart Study: Refiners with Low Sulfur Capabilities Likely to Fare Better over the Coming Decade
“The nectarine, and curious peach, / Into my hands themselves do reach; / Stumbling on melons, as I pass, / Ensnared with flowers, I fall on grass.” -- Andrew Marvell (English Poet, Politician and Satirist. 1621-1678)
News that can affect the direction of desulfurization research comes from many sources, including press releases like the following …
“HOUSTON, TEXAS (Jan. 12, 2010) – Low sulfur diesel and gasoline are likely to spearhead an economic recovery for the refining industry just beyond 2010, a study from Hart Energy Consulting shows.
"Strong global GDP growth (2.7%) in 2010 should buttress refined petroleum product demand, especially in the Asia Pacific region and other emerging markets. Over the next decade, global demand will grow by 1.7% annually and Asia Pacific will account for nearly half that increase. Worldwide environmental initiatives will spur even higher growth in lower sulfur products. Demand for low sulfur gasoline and diesel will increase by nearly 17 million barrels per day by 2020 (more than 70% increase). The oversupply situation in gasoline will be offset by a tight demand/supply balance for clean diesel.
"The full study covers petroleum product demand and supply, country specific and global crude and NGL production, as well as a thorough analysis of the impact of environmental regulation and public policy requirements. This year Hart Energy Consulting added a special review of the impact of current issues such as:
"o Developing climate policies on vehicle fleet and fuel quality and demand
"o Economic subsidies on supply & demand of renewable and low-carbon fuel
"o A short-term economic recovery: crude oil prices forecast, GDP forecast, vehicle

FCC Network News April 2010 Volume 36ENERGY SAVING RETROFIT OF AN FCC PLANTFollowing is an excerpt from a recent NPRA paper by G. T. Polley and J. D. Kumana summarizing several potential approaches to improving the energy efficiency of an FCC unit. The entire paper has been posted to The FCC Network website under the “Technical Papers“tab in the category “FCCU Optimization Tools & Technologies”. Mr. Kumana, who is now a principal in Kumana & Associates, will be presenting a seminar, entitled “Energy Efficiency in Refineries” on May 5, 6, 7, 2010 in Houston, Texas. For more information on this or other training programs, visit www.petroleumrefining.com .
ABSTRACT The use of process integration techniques to optimize the energy efficiency of process plants is now a widely accepted practice. However, the results obtained vary considerably as there is no “standard” way of doing things, and despite having a sound theoretical basis for the method, actual application remains an art. In 2005, Saudi Aramco arranged for three different consulting firms to develop retrofit designs for a “standard” problem. Each consultant used a different methodology. The aim was to assess which methodology gave the best results. The problem chosen for the study was drawn from the literature [Al-Riyami et al]. None of the consultants used the methodology used in the original study. Consequently, four different approaches could be assessed.

“Want to Read Arabic News? Click Here”
“Change your language and you change your thoughts.” -- Karl Albrecht (born 20 February 1920) German entrepreneur and co-founder of the discount supermarket chain Aldi
Tunnel vision is an occupational hazard for the technologist. Inoculate yourself with a dose of general news. And if you’re in the oil business, that news should include the Middle East. Here’s an interesting site that I found in a recent article published by the Christian Science Monitor (http://www.csmonitor.com/)

“Want to Read Arabic News? Click Here”
A new translation Website links English and Arabic speakers
By Tom A. Peter
[Excerpts from the article]
“Despite a post-9/11 surge of Westerners learning Arabic … English and Arabic speakers are largely segregated on the Web.
“A new translation website called Meedan (www.meedan.net ) aims to close that gap. Meedan is creating a public forum for English and Arabic speakers to translate, read, and debate Middle East news.
“Relying on a combination of machine and human translation, the site offers Middle East news on pages split between English and Arabic. When users comment on a story, responses are automatically translated into either English or Arabic.
“Unlike automated sites such as Google Translate, Meedan utilizes humans as well as computers to provide clearer translations.”

Expert Alert: King Saud University Distinguished Scientist Fellowship Program
The First Clarke Law states, 'If an elderly but distinguished scientist says that something is possible he is almost certainly right, but if he says that it is impossible he is very probably wrong.' Sir Arthur Charles Clarke, CBE, FRAS (16 December 1917 – 19 March 2008) was a British science fiction author, inventor, and futurist, most famous for the novel 2001: A Space Odyssey, written in collaboration with director Stanley Kubrick (source: http://en.wikipedia.org/wiki/Arthur_C._Clarke )
Despite the bad press that Saudi Arabia gets, the country actually has a number of interesting programs. One of them is the King Saud University Distinguished Scientist Fellowship Program (http://ksu.edu.sa/AboutKSU/HighlycitedResearchers/Pages/Researchers.aspx ). In the somewhat florid words of its Web …
“It is the vision of Professor Ali Al-Ghamdi and Prof. Khaled A. S. Al-Rasheid that KSU’s significant reforms should be internationally visible and contribute to the university’s world recognition. Therefore, they proposed and are currently implementing a well structured, visionary and pragmatic work plan in order to achieve the University aim in becoming a research-led institution.
“Most of strategic reforms and plans that the KSU has already undertaken to improve its education, research and enterprise, may not be visible to the international community. These reformation and developmental plans should be published in order to give KSU the recognition and reputation it deserves and to highlight the huge efforts and resources committed to elevate standards of education, research and enterprise.
“To this end, the University has recruited and acquired the input of number of highly cited researchers who are specialist in various research fields with outstanding careers as part of Distinguished Scientist Fellowship Program.”

Use Patents to Discover Desulfurization Organizations
“One of the advantages of being disorderly is that one is constantly making exciting discoveries.” -- A. A. Milne (English Humorist, creator of Winnie-the-Pooh, 1882-1956)
Patent searches can produce a variety of useful information beyond the specific technologies described in the patent documents themselves.
Monitor patents to accomplish any of the following …
1 Determine the possible strategic implications of a competitor’s approach to a given problem
2 Identify potential licensing partners to help solve a particular technological problem
3 Find potential presenters for technical conferences, workshops, and symposia to be sponsored by your organization
You will find other uses as you put your imagination to work.
By way of example, here are a few results from a recent PatentStorm (www.patentstorm.us) search on "dibenzothiophene" Note the organization listed in the Assignee or Attorney field. Companies like TotalFina and Honeywell will come as no surprise. The University of Michigan, however, may not have been on your radar.

No. 10726935 filed on 12/03/2003
Abstract
A method for removing thiophene and thiophene compounds from liquid fuel includes contacting the liquid fuel with an adsorbent which preferentially adsorbs the thiophene and thiophene compounds. The adsorption takes place at a selected temperature and pressure, thereby producing a non-adsorbed component and a thiophene/thiophene compound-rich adsorbed component. The adsorbent includes either a metal or a metal cation that is adapted to form π-complexation bonds with the thiophene and/or thiophene compounds, and the preferential adsorption occurs by π-complexation. A further method includes selective removal of aromatic compounds from a mixture of aromatic and aliphatic compounds.

New Journal from the Royal Society of Chemistry
"When you look at Prince Charles, don't you think that someone in the Royal family knew someone in the Royal family?" -- Robin Williams
Sulfur is a problem at every point in the hydrocarbon life cycle … from the time that the hydrocarbons are extracted to the time the residue of their waste enters the environment. A new journal published by The Royal Society of Chemistry (http://www.rsc.org/) can help you follow developments in technologies created to address the sulfur problem … as well as other problems … at every stage.
Energy & Environmental Science
“A new journal linking all aspects of the chemical sciences relating to energy conversion and storage, alternative fuel technologies and environmental science”

Here, for example, are a couple of recent articles appearing in the journal …
Removal of Refractory Organosulfur Compounds via Oxidation with Hydrogen Peroxide on Amorphous Ti/SiO2 Catalysts
Authors: Capel Sanchez, Maria del Carmen, Campos Martín, Jose Miguel, Fierro, Jose L. G.
Issue Date: 10-Feb-2010
Efficient removal of benzothiophene (BT), dibenzothiophene (DBT) and 4,6-dimethyldibenzothiophene (DMDBT) has been successfully achieved via oxidation with hydrogen peroxide in liquid phase using an amorphous silica-loaded titanium oxide catalyst. Both BT and DBT are easily oxidized to the corresponding sulfones, however in the case of DMDBT the steric hindrance of the alkyl groups makes the approach of the S-atom to the catalyst active centre (an isolated Ti(IV) species) difficult and therefore its reactivity is inhibited. The concentration of the organosulfur compound, the H2O2 concentration and the nature of the solvent play a key role in the rate of S-removal.
Selective catalytic oxidation of H2S to elemental sulfur over V2O5/Zr-pillared montmorillonite clay
Kanattukara Vijayan Bineesh, Dong-Kyu Kim, Dong-Woo Kim, Han-Jun Cho and Dae-Won Park, Energy Environ. Sci., 2010, 3, 302
DOI: 10.1039/b921937d
Vanadia-doped zirconia-pillared clays (V/Zr-PILCs) were synthesized and used as catalysts for the selective catalytic oxidation of H2S

ResearchGate
“Even Napoleon had his Watergate.” -- Yogi Berra quotes (American professional Baseball Player and Manager. b.1925)
As a college student during the notorious Watergate scandal, I was outraged by the arrogance of power displayed by certain men at the top of the political pyramid. At the same time, I was encouraged to see that men and women of principle still existed. Likewise, I am encouraged by a site like ResearchGate (www.researchgate.net). It makes me think the Internet still has more to offer than entertainment and infomercials.
Part social network, part search engine, the ResearchGate Web describes itself as follows …
“The vision of Science 2.0 is promising: Communication between scientists will accelerate the distribution of new knowledge. Without anonymous review processes, the concept of open-access journals will assure research quality. Science is collaboration, so scientific social networks will facilitate and improve the way scientists collaborate. Cooperation on scientific publications can be facilitated through Wiki-like concepts.
“Science 2.0's concepts will have to be developed with the science community. Change will happen. The question is just when and how.
“ResearchGATE is an essential part of the Science 2.0 community and will evolve with it.”
Even if you are skeptical of joining another social network, you should bookmark this site. It offers another way to search across a number of databases for journal articles pertaining to your topic.

Abstract
Microbial fuel cells (MFCs) have gained a lot of attention in recent years as a mode of converting organic waste including low-strength wastewaters and lignocellulosic biomass into electricity. Microbial production of electricity may become an important form of bioenergy in future because MFCs offer the possibility of extracting electric current from a wide range of soluble or dissolved complex organic wastes and renewable biomass. A large number of substrates have been explored as feed. The major substrates that have been tried include various kinds of artificial and real wastewaters and lignocellulosic biomass. Though the current and power yields are relatively low at present, it is expected that with improvements in technology and knowledge about these unique systems, the amount of electric current (and electric power) which can be extracted from these systems will increase tremendously providing a sustainable way of directly converting lignocellulosic biomass or wastewaters to useful energy. This article reviews the various substrates that have been explored in MFCs so far, their resulting performance, limitations as well as future potential substrates.

Nano ZnO

OK, nanu is not nano, but isn’t that a great quote? I loved that show. But now to business.

Abstract
Zinc oxide (ZnO) nano-particles have been synthesized by a matrix-assisted method with various precursors. An activated carbon was used as a matrix and zinc acetate, zinc nitrate, and zinc chloride were selected as precursors. The ZnO nano-particles appeared to be either spherical or elliptical shapes when zinc acetate and zinc nitrate were used as precursors, while those particles became irregular in their shapes when zinc chloride was used as a precursor. The products were characterized by using TGA, XRD, BET, TEM and SEM. A nano-size ZnO was formulated for the effective removal of a very low concentration of sulfur compounds (H2S, COS) contained in a gasified fuel gas and their reactivity was also investigated in this study. Zinc acetate was the best precursor for the formulation of the ZnO nano-particles in the experiment. The size of the formulated ZnO nano-particles was in the range of 10–30 nm and its surface area was about 40.7 m2/g. From TGA (thermal gravity analysis) test, it was found that its sulfur capacity was about 9.27 g S/100 g-sorbent for H2S and 0.56 g S/100 g-sorbent for COS and its initial sulfur absorption rates with H2S and COS absorption were about 257.5 mg S/min • 100 g-sorbent and 15.6 mg S/min • 100 g-sorbent, respectively. Their reactivity increased as their sizes became smaller and their surface areas of the sorbents were larger. Most prepared nano-size ZnO showed an excellent performance for the removal of not only H2S but also COS.

Keywords: desulfurization, nanosize ZnO, XANES, EXAFS
Abstract:
Thermal efficiencies of an integrated gasification combined cycle (IGCC) process can be enhanced with high-temperature desulfurization. Nanosize, sub-nano (clusters) and atomic-dispersed ZnO has been prepared for the high-temperature desulfurization. An enhanced absorbance of the nanosize ZnO at 9668 eV is found by X-ray absorption near edge structure (XANES) spectroscopy (Figure 1). ZnO clusters are also observed in the channels of MCM-41. By temperature programmed sulfurization (TPS) and oxidization (TPO), it is found that the nanosize ZnO can be effectively sulfurized and regenerated (with air) at 940-950 K (Figure 2). The smaller ZnO clusters in MCM-41 can be sulfurized at relatively lower temperatures (700-820 K). The atomic dispersed ZnO on TiO2 having the strong metal-support interactions cannot be sulfurized at the temperature of < 960 K, and interestingly, regenerated at much lower temperatures (i.e., <650 K). It seems that the nanosize or atomic dispersed ZnO may be desired for the high-temperature desulfurization especially for a high efficiency IGCC based electric power generation.

Abstract
The application of several titanosilicates to the oxidation of aromatic sulfur compounds such as thiophene, benzothiophene, dibenzothiophene, and 4,6-dimethyldibenzothiophene with H2O2 under mild conditions is reported. Superior to other titanosilicates, Ti-MWW demonstrates a higher activity for the oxidation of 4,6-dimethyldibenzothiophene owing to the unique pore structure of the MWW topology. The effects of solvent, temperature, catalyst amount, and H2O2/S ratio on the oxidation of 4,6-dimethyldibenzothiophene over this catalyst are studied in detail. The catalyst is also applied to the oxidative desulfurization of commercial diesel. The sulfur compounds in the commercial diesel were oxidized to the corresponding sulfones, which could be readily extracted by acetonitrile, resulting in a maximum sulfur removal of 88 % .

Abstract
Environmental concerns have introduced a need to remove sulfur-containing compounds from light oil. As oxidative desulfurization is conducted under very mild reaction conditions, much attention has recently been devoted to this process. In this contribution, the developments in selective removal of organosulfur compounds present in liquid fuels via oxidative desulfurization, including both chemical oxidation and biodesulfurization, are reviewed.

Expert Alert: Dr. Abdul-Majeed Azad
"The best tank terrain is that without anti-tank weapons." -- Russian military doctrine
Military funded research produces much that can be applied to civilian life. The following article is a case in point …
A.-M. Azad and S. Desikan, "A novel desulfurizer-reforming catalyst combination for logistic fuel reforming,” AMMTIAC Quarterly: Special Issue on Powering the Future Force, New Power & Energy Technologies for the Warfighters, 4 (#1) (2009) 65-68. (Download).
"Editor’s Note: Many different approaches will be required to provide the warfighter with a full spectrum of power and energy solutions. One of the more promising of these is fuel cell technology. However, some of the major hurdles for fuel cells to clear include developing suitable hydrogen-rich fuels to sustain them and being able to produce these fuels in both an efficient and environmentally-friendly manner. This article is a summary of leading edge research in the development of new catalytic materials to enhance the production of the needed fuels. This state-of-the-art work was performed by Dr. Abdul-Majeed Azad and his graduate student Desikan Sundararajan of the University ofToledo. If you are interested in learning more about this technology or would like to contact the authors, please contact the AMMTIAC Editor."
From the introduction:
"The best way to overcome these challenges would be to develop a new generation of effective desulfurizer and sulfur-tolerant reforming catalysts. Meeting these two objectives, specifically an agile desulfurizer capable of sorbing sulfur in the fuel and a sulfur tolerant catalyst that can tolerate the brunt of a small level of sulfur left uncaptured by the sulfur sorbent, calls for innovative approaches. The research summarized in this article highlights the feasibility of generating clean electric power using desulfurized hydrogen-rich reformates from logistic fuels with reduced environmental impact."

Meeting these two objectives, specifically an agile desulfurizer capable of sorbing sulfur in the fuel and a sulfur tolerant catalyst that can tolerate the brunt of a small level of sulfur left uncaptured by the sulfur sorbent, calls for innovative approaches. The research summarized in this article highlights the feasibility of generating clean electric power using desulfurized hydrogen-rich reformates from logistic fuels with reduced environmental impact."
