Abstract
In this paper, fuel-processing technologies are developed for application in residential power generation (RPG) in solid oxide fuel cells (SOFCs). Kerosene is selected as the fuel because of its high hydrogen density and because of the established infrastructure that already exists in South Korea. A kerosene fuel processor with two different reaction stages, autothermal reforming (ATR) and adsorptive desulfurization reactions, is developed for SOFC operations. ATR is suited to the reforming of liquid hydrocarbon fuels because oxygen-aided reactions can break the aromatics in the fuel and steam can suppress carbon deposition during the reforming reaction. ATR can also be implemented as a self-sustaining reactor due to the exothermicity of the reaction. The kW{sub e} self-sustained kerosene fuel processor, including the desulfurizer, operates for about 250 h in this study. This fuel processor does not require a heat exchanger between the ATR reactor and the desulfurizer or electric equipment for heat supply and fuel or water vaporization because a suitable temperature of the ATR reformate is reached for H{sub 2}S adsorption on the ZnO catalyst beds in desulfurizer. Although the CH{sub 4} concentration in the reformate gas of the fuel processor is higher due to the lower temperature of ATR tail gas, SOFCs can directly use CH{sub 4} as a fuel with the addition of sufficient steam feeds (H{sub 2}O/CH{sub 4} {>=} 1.5), in contrast to low-temperature fuel cells. The reforming efficiency of the fuel processor is about 60%, and the desulfurizer removed H{sub 2}S to a sufficient level to allow for the operation of SOFCs.

Abstract
Hydrogen is now in demand for heavy oil upgrading, desulfurization, and petroleum upgrading processes. Hydrogen production will be needed on a massive scale if it is to be used as a transportation and portable power fuel. This study examined methods of producing hydrogen using renewable energy sources derived from agricultural and other waste streams. Use of these materials offers the possibility of contributing to hydrogen production without the creation of additional greenhouse gases (GHGs) and may also increase the flexibility and economics of distributed and centralized reforming processes. The study showed that electrolysis, thermocatalytic, and biological hydrogen production methods can be easily adapted to semi-centralized reforming procedures. A distributed network of on-site production facilities may provide a cost-effective refueling infrastructure. However, conversion efficiencies, and purification and storage technologies will need to be improved before the methods are widely adopted. It was concluded that a new national strategic network has been established in Canada to study issues related to hydrogen purification, storage, infrastructure.

Abstract
Two Claus plants in Kirkuk, Iraq, convert hydrogen sulfide to elemental sulfur at a capacity of 2,200 tons/day. One of the plants is working at a capacity of only 400 tons/day with an old Claus process. The other uses a modified Claus sulfur recovery process with a capacity of 1800 tons/day. Both of the plants operate with low efficiency due to lack of maintenance. As such, the agricultural area surrounding Kirkuk is highly polluted. This paper described 2 pilot desulphurization plants that have been constructed inside the modified Claus plant. The first pilot plant is based on the flow system tube furnace reactor containing mixed titanium oxide/sulfide with a cold trap for sulfur separation and a bath of 30 per cent dithanolamine to separate and recycle hydrogen sulphide (H{sub 2}S) from hydrogen. The second pilot plant consists of a thermal diffusion ceramic rod inside a silica column containing zeolite 5A as a catalyst. This pilot plant also consists of a trap for continuous separation of sulfur and a system for separation of hydrogen from unreacted H{sub 2}S to recycle. The efficiency of conversion of H{sub 2}S to hydrogen and sulfur has been optimized as a function of catalyst type and mixture, temperature of furnace, flow rate of gas and reactor materials. The pilot plants were suitable with cadmium chalcogens catalysts to produce hydrogen, methane, ethane and sulphur, but with lower efficiency than H{sub 2}S decomposition only. The goal for the second pilot plant was to supply the heat using a solar energy concentrator instead of electricity. It was concluded that a hydrogen production plant in this part of Iraq will save a large area from polluted sulfur gas. The pilot plants can produce about 140 tons of hydrogen gas per day from these waste gases.

Language: English
Abstract
Ultra low hydrodesulfurization of straight run and conversion middle distillates and mixtures thereof was carried out on a high performance commercial Co-Mo catalyst in a trickle bed pilot plant with the aim to develop a correlation that predicts hydrogenate sulfur from physical and chemical properties of the feedstock. It was found that by using a 1.5 order kinetic model the rate constants correlate with total sulfur, dibenzothiophenes, total nitrogen, total aromatics and poly nuclear aromatics content and the content of the material boiling above 340 C (according to simulation distillation ASTM D-2887 of the middle distillate). The correlation proved to accurately predict the hydrogenate sulfur in a Lukoil Neftochim Bulgaria (LNB) refinery hydrodesulfurization (HDS) unit. The correlation could be applied for optimization of production of near zero sulfur diesel (NZSD) in a refinery. (orig.)

CO2 Sequestration in Cell Biomass of Chlorobium Thiosulfatophilum
James L. Gaddy, PhD; Ching-Whan Ko, PhD
2009 May 04
Report Number(s): DOE/ER/83907-3
Language: English
Abstract
World carbon dioxide emissions from the combustion of fossil fuels have increased at a rate of about 3 percent per year during the last 40 years to over 24 billion tons today. While a number of methods have been proposed and are under study for dealing with the carbon dioxide problem, all have advantages as well as disadvantages which limit their application. The anaerobic bacterium Chlorobium thiosulfatophilum uses hydrogen sulfide and carbon dioxide to produce elemental sulfur and cell biomass. The overall objective of this project is to develop a commercial process for the biological sequestration of carbon dioxide and simultaneous conversion of hydrogen sulfide to elemental sulfur. The Phase I study successfully demonstrated the technical feasibility of utilizing this bacterium for carbon dioxide sequestration and hydrogen sulfide conversion to elemental sulfur by utilizing the bacterium in continuous reactor studies. Phase II studies involved an advanced research and development to develop the engineering and scale-up parameters for commercialization of the technology. Tasks include culture isolation and optimization studies, further continuous reactor studies, light delivery systems, high pressure studies, process scale-up, a market analysis and economic projections. A number of anaerobic and aerobic microorgansims, both non-photosynthetic and photosynthetic, were examined to find those with the fastest rates for detailed study to continuous culture experiments. C. thiosulfatophilum was selected for study to anaerobically produce sulfur and Thiomicrospira crunogena waws selected for study to produce sulfate non-photosynthetically. Optimal conditions for growth, H2S and CO2 comparison, supplying light and separating sulfur were defined. The design and economic projections show that light supply for photosynthetic reactions is far too expensive, even when solar systems are considered. However, the aerobic non-photosynthetic reaction to produce sulfate with T. crunogena produces a reasonable return when treating a sour gas stream of 120 million SCFD containing 2.5 percent H2S. In this case, the primary source of revenue is from desulfurization of the gas stream. While the technology has significant application in sequestering carbon dioxide in cell biomass or single cell proten (SCP), perhaps the most immediate application is in desulfurizing LGNG or other gas streams. This biological approach is a viable economical alternative to existing hydrogen sulfide removal technology, and is not sensitive to the presence of hydrocarbons which act as catalyst poisons.

Abstract
Direct oxidation of dibenzothiophene (DBT) based on molecular oxygen and iron tetranitrophthalocyanine (FePc(NO{sub 2}){sub 4}) catalyst was performed in hydrocarbon solvent under water-free condition for deep desulfurization. Conversion of DBT in decalin reached 98.7 wt.% at 100 C and 0.3 MPa of initial pressure with 1 wt.% of FePc(NO{sub 2}){sub 4} over the whole solution for 2 h. In addition to FePc(NO{sub 2}){sub 4}, another two catalysts, FePc(NO{sub 2}){sub 3}NH{sub 2} and FePc(NH{sub 2}){sub 4}, were synthesized to investigate the effect of substituents of iron phthalocyanines on their catalytic activities. The results show that the catalytic activity of these phthalocyanines decreases in the order of FePc(NO{sub 2}){sub 4} > FePc(NO{sub 2}){sub 3}NH{sub 2} > FePc(NH{sub 2}){sub 4}, indicating that the electron-donating group has negative effect on the catalytic properties. Activity of FePc(NO{sub 2}){sub 4} was kept unchanged after 5 runs of oxidation; whereas, activity of FePc(NH{sub 2}){sub 4} decreased because of its decomposition. Moreover, FePc(NO{sub 2}){sub 3}NH{sub 2} was supported on a polyacrylic cationic exchange resin and its activity was remarkably enhanced to the level of FePc(NO{sub 2}){sub 4}. Oxidative desulfurization of a model fuel, 500 {mu}g/g solution of DBT in decalin, was performed based on the catalytic oxidation using molecular oxygen and FePc(NO{sub 2}){sub 4} catalyst. The lowest sulfur content in the model fuel could be decreased to less than 4 {mu}g/g after the treatment of this oxidation and a combined adsorption. (author)

Blind Alleys

Research is the act of going up alleys to see if they are blind.
-- Plutarch


Years ago a customer came to me with a simple request. He wanted the technical specifications of the various types of crude oil … Arabian Light, West Texas Intermediate, the lot. “No problem,” I said, and went to the shelf which housed the EIG Crude Oil Market Handbook (http://www.energyintel.com/DataHomePage.asp?publication_id=103&ss=e). I had fielded similar questions dozens of times before and knew the answer. In this case, unfortunately, it was the wrong answer.

My customer said, “No, I need more detail than that.”

Then I asked him the question I should have asked before … “What are you going to use the information for?

He told me that he wanted independent detailed assays of a broad range of crude which he could then compare to values R&D had compiled over the years and placed in a database. They were going to use the data in a research project and wanted to validate the data before beginning the project.

And so began the process of going down blind alleys to see what was there. How many blind alleys were involved I cannot say. I lost count after about 372. But this was a good customer. I was determined to go the extra two or three miles needed to find information he could use.

I finally found the right blind alley … and in that alley, I discovered …

A Catalogue of Crude Oil and Oil Product Properties

The 546 page report was funded by the U.S. Minerals Management Service and Environment Canada. Its purpose was to provide a fingerprint of every conceivable type of crude that might become the subject of an oil spill cleanup. Consequently, the properties of each crude were examined in great detail and are reported in this document.

My customer was very pleased with the results. And the results came about by asking the right question, and then going down blind alleys to see what was there.

Get Help! (And how to make the most of the help you get)

At some point in your research you will find you don’t have time to do it all yourself. At that point, you should contact your corporate librarian, if there is one. If not, contact an independent information professional (IP) like Jean Steinhardt Consulting LLC.

Whoever you choose, here is how you can get the best results …
1) Keywords: desulfurization is a good keyword, but can result in a huge number of hits. A more specific keyword, a keyword that is widely used in your area of expertise but that is more technical in nature, may be better. For example, if your research focuses on “dibenzothiophene,” let the IP (information professional) know that.
2) Context: Continuing with the dibenzothiophene example, are you focused on the fuel cell part of the hydrocarbon chain, or are you more interested in refining heavy crude?
3) Purpose: why do you need the search? Are you looking for the latest trends? Or are you working on a patent application and want to be sure no one else has already patented the concept? Or are you wondering about the marketability of your concept?
4) Turnaround: when do you need to see the results? The faster you need them, the more it is likely to cost. If speed is more important than money, let your IP know that.
5) Cost: how much are you willing to spend? Even if you are lucky enough to have a corporate librarian at your disposal, he / she will need to spend time and money researching your topic.
6) To the Max: even if you need this done FAST, you might do well to agree a not-to-exceed amount ahead of time. When your IP gets to the agreed amount, you can review the results and determine whether to continue.

As to the question of how to find the right IP for your purpose, take a moment to read “Shopping for an Information Broker” by Mary Ellen Bates (http://www.batesinfo.com/searcher-article.html)

Abstract
A new method has been recently developed for the hydrodesulfurization of gasoils based on the formation of charge transfer complexes. This method is highly selective towards the removal of alkyldibenzothiophenes from other aromatic compounds present in gasoils. Total energy calculations based on density-functional theory have been performed to study the complexation phenomenon and clarify its high selectivity. DFT calculations improve the understanding of the process and they are also useful for the design of more efficient acceptor derivatives for the desulfurization process. Five charge transfer complexes between a given acceptor and five representative donor compounds present in gasoils have been studied. Three main criteria have been used to characterize the optimized complexes: their complexation energy, their geometry and their electronic structure. The decomposition of total energy showed that the main contribution to the complexation energy comes from the Pauli repulsion and the electrostatic interactions. Hence the charge transfer complexes are not only ruled by charge transfer but also by electrostatic contributions. However, the selectivity of the complexation phenomenon is controlled by the orbital interactions.

The Case for KAUST

This is amazing. KAUST – King Abdullah University of Science & Technology (http://www.kaust.edu.sa/) -is an ambitious project of the Saudi government to create a world class university that will attract world renowned scholars and top caliber students from the globe.

It was started from scratch in the summer of 2006, with the goal of being fully operational by September 2009. This in itself is astonishing.

But what I find amazing is that Saudi Aramco, the national oil company, was assigned the task of making this happen.

And yet, there is a certain logic to the assignment. If there is one thing that distinguishes one oil major from another, it is the quality of the technical expertise at its disposal. What better way to access that expertise than to be involved in the creation of a world class educational institution dedicated to the development of that expertise?

How does this pertain to desulfurization? Saudi Aramco, like other majors, is dealing with the fact that the supply of high quality oil is shrinking. There is still lots of heavy crude, but to make it marketable, economically feasible desulfurization technologies are required.

Here are a few resources to explore for more background, along with selected quotes.

Saudi Aramco Annual Review (2008)
In the summer of 2006, the government directed us to lead the development of the King Abdullah University of Science and Technology, or KAUST, a decades-long vision of King Abdullah. KAUST is setting new precedents in a variety of areas for research universities. The university's organization and endowment, its interdisciplinary approach and partnerships with other institutions, its physical campus and unique setting, and its approach to recruiting faculty and students from around the world have all set new standards in higher education.

“The project is situated on a site of more than 36 million square meters on the Red Sea approximately 80 km north of Jiddah. KAUST will be an international, graduate-level research university open to men and women from around the world and dedicated to inspiring a new age of scientific achievement in the Kingdom that will also benefit the region and the world.

“In June 2008, we signed a memorandum of understanding with KAUST to create a partnership to support carbon emissions research, advanced petroleum reservoir and oil recovery technologies, and energy conservation and marine environment studies.

Institute of Energy Research

The Institute of Energy Research (IEF) (http://www.fz-juelich.de/portal/about_us/institutes_facilities/institutes/ief), according to its Web site, “investigates modern energy conversion technologies. The topics it covers range from photovoltaics and fuel cells, through nuclear fusion and nuclear safety research, right up to innovative coal and gas power plants. This gives rise to an unrivalled breadth of research topics, all bound together by scientific methods and systems analysis.”

One of its areas of focus is fuel cells, and within that focus is another concern … desulfurization of the fuel that fuel cells require. Here are several publications listed on the site …

Time-savers: OSTI Information Bridge

Another time-saver for the focused researcher is to search the OSTI Information Bridge (http://www.osti.gov/bridge/). Searching “dibenzothiophene” for the years 2005-2009 resulted in the list below. A nice feature is that the PDF of the full report is available for download.

What’s In a Name: Petrotech 2010

I complained in a previous post about the fact that a search for “Aramco conference 2010” resulted in a hit on Middle East Petrotech 2010 that had no information on Petrotech 2010. I was too quick to whine … a subsequent search for “Middle East Petrotech 2010” resulted in slightly more current information, including the names of the committee members, shown below. Names like these can be significant to desulfurization research because they are either the decision makers, or know the decision makers, that will fund your research and/or buy your research results.

To Infinity and Beyond: More Conferences

Searching for conferences can be frustrating, but there is wheat among the chaff. For example, a search for “Aramco conference 2010” resulted in a list including an announcement of Middle East Petrotech 2010, which does not yet have any information about 2010 (frustrating). It does, however, include information about “high level guest speakers” at the 2008 conference. The names of some of the speakers are familiar … the names of others, less so. Here they are …

High level guest speakers during the course of the conference at the Bahrain International Exhibition Centre included Robert Hutchinson, Vice President Chemicals, ExxonMobil Saudi Arabia; Maurice Bannayan, Senior Vice President, Reliance Industries Limited; Khalid G. Al-Buainain, Senior Vice President, RM&I, Saudi Aramco; Maha Mulla Hussain, Managing Director, Petrochemical Industries Company (PIC) Kuwait; Bill Spence, Vice President CO2, Shell Downstream Services International B.V.; Abdulkarim Al-Sayed, Chief Executive Officer, BAPCO; Michael R. Gambrell, Executive Vice President, Basic Plastics and Chemicals, Manufacturing & Engineering, DOW Chemical Company; Dr. Fatih Birol, Chief Economist, International Energy Agency; and Khamis Bu-Amim, President and CEO, Regional Clean Sea Organization (RECSO).

Sometimes, the Government Gets It Right: Science.gov

As a more focused alternative to Google®, Yahoo!® et al, try Science.gov (www.science.gov) In a quick search for “dibenzothiophene,” I obtained results that I could have gotten with the popular search engines, but with much less clutter.

The side bar that pops up next to the search results lets you refine your search with a click. When I clicked on “Sulfur Removal” a list of 46 hits appeared. The first 10 hits are reproduced below …

CONFERENCES

Attending conferences is a time-honored way to network and to keep abreast of new developments in your field. If you can’t attend a conference, the next best thing is to go to the conference Web site and browse the topics being addressed. Sometimes you will spot the name of a presenter who you know. Other times you will pick up a new name, who is presenting on a topic of particular interest to you. From there, it is a simple matter to send an email or make contact in some other way.

Here a few examples …

The DOE’s Catalysis Science Program produces impressive results. Browse through Frontiers in Catalysis-Advanced Synthesis, Characterization, Modeling (2009) to see what the program is designed to do. Included in the document are items specific to desulfurization, but since everything connects to everything else, it is good to get a sense of what is happening in other areas of catalysis, as well.

The Devil & the Deep Blue Sea: Searching The Hidden Web

You may have heard of the Deep Web, which is the 85% of the Internet that is NOT found by Web crawlers like Google and Yahoo! Wikipedia has a good description of this ocean of information (http://en.wikipedia.org/wiki/Deep_web) In practical terms, this means that you can’t find everything you want just by searching Google. You have to search multiple sites, one at a time.

To demonstrate … the results of searching for recent items containing the two keywords “desulfurization AND gasoline” in the sources listed below revealed a surprising lack of duplication.

h-Index

Catalysis for Energy: Fundamental Science and Long-Term Impacts of the U.S. Department of Energy Basic Energy Science Catalysis Science Program” (National Academies Press, 2009) is filled with useful information, beyond the obvious. For example, take a look at TABLE 3-5 H-index ranking of select prominent chemists with relevance to the Catalysis Science Program, according to 2008 H-Index, H-Index Rank, and Field of Chemistry (other prominent chemists listed for comparison). The h-Index, according to Wikipedia (http://en.wikipedia.org/wiki/H-index) “…is an index that attempts to measure both the scientific productivity and the apparent scientific impact of a scientist.”

Table 3-5 lists those h-index chemists that are relevant to the Catalysis Science Program. Because catalysis research lies at the core of advancing effective desulfurization technology, the table is an excellent starting point for identifying potential consultants with expertise in your area of interest.
