“Opportunity is missed by most people because it is dressed in overalls and looks like work.” -- Thomas Alva Edison
Large organizations support libraries. Academic institutions support them for reasons both practical and legal … without an academic library which meets academic standards, the accreditation of the entire institution is jeaopardized.
Organizations like Exxon and Saudi Aramco support them because they know that without them, they will spend more for the information they require to remain competitive and profitable . or, what is worse, miss an important opportunity by not acquiring the informtion at all.
Small businesses have a difficult time justifying the expense … typically, they are lucky to make payroll each month.
However, at some point on its road to success, a company gets large enough that even the C3 … the CEO, CFO and CIO … recognize that employing an information professional makes economic sense.
If you are a desulfurization expert in a midsize organization, you can do yourself and your colleagues a favor by advocating to upper management that they employ a librarian.
The three most important things a librarian can provide …
1) Research … searching publicly available sources for articles, conference papers, and presentations pertaining to a specified research topic
2) Advice … advising on best practices for managing your print and online resources to fit your research needs
3) Training … educating your users to make the most effective use of their time researching topics on the Web’s free and subscription based databases
If I were setting up a library in your organization, I would be sure that the librarian had access to the following, at a minimum …
a) Dialog … for literature searches
b) SAI ILI Infodisk … for industry standards
c) TDI & Ingenta … for document delivery
d) Corporate credit card … for ordering information items not covered by existing accounts set up with various providers.
So much of what we need is available on the Internet these days … but so much of what is on the Internet COSTS MONEY. A librarian can help you spend that money strategically.

The Search for Standards: ASTM
"The nicest thing about standards is that there are so many of them to choose from” -- Andres S. Tannenbaum
Industry standards are an important component of desulfurization research. Identifying the standards that apply to a given situation can be a challenge. One place to start is ASTM International (http://www.astm.org/) . The site has a good search capability, and once you have identified the standards you need, you can purchase them for immediate download.
For example, searching for “sulfur” in the ASTM Standards and Engineering Digital Library (http://www.astm.org/DIGITAL_LIBRARY/index.shtml) you will find a number of hits, including …
D5623-94(2009) Standard Test Method for Sulfur Compounds in Light Petroleum Liquids by Gas Chromatography and Sulfur Selective Detection
Significance and Use
Gas chromatography with sulfur selective detection provides a rapid means to identify and quantify sulfur compounds in various petroleum feeds and products. Often these materials contain varying amounts and types of sulfur compounds. Many sulfur compounds are odorous, corrosive to equipment, and inhibit or destroy catalysts employed in downstream processing. The ability to speciate sulfur compounds in various petroleum liquids is useful in controlling sulfur compounds in finished products and is frequently more important than knowledge of the total sulfur content alone.

Search engine: Openj-gate
"Drawing on my fine command of the English language, I said nothing" -- Robert Benchley
The Web is repository for an enormous number of desulfurization related documents. Much of the most useful content, however, resides behind fee based portals like ScienceDirect and Ebsco Academic, to name two.
Openj-gate (www.openj-gate.com ) is an exception to this …
Try it out by searching for "dibenzothiophene." Using the advanced search feature, you can restrict the results to a date range, such as 2009-2010.
The results of the search appear below. In each case, a free full text version of the cited article is available for download.
Openj-gate is not a huge repository, and many of the articles are written in languages other than English, which can be a problem for those of us with limited language skills. But it is worth bookmarking for occasional use to supplement your searches in other databases.

Degradation of Benzo [a] Pyrene by a novel strain Bacillus subtilis BMT4i (MTCC 9447)
Author(s) : Lily, Madhuri Kaushish; Bahuguna, Ashutosh; Dangwal, Koushalya; Garg, Veena;
Source : Brazilian Journal of Microbiology ; Vol.40 No.4 Dec 2009 [Page 884-892]
Keyword(s) : Benzo [a] Pyrene (BaP); polycyclic aromatic hydrocarbon (PAH); Bacillus subtilis BMT4i; colony forming units/ml (CFU/ml); high performance liquid chromatography (HPLC).;
Abstract : Benzo [a] Pyrene (BaP) is a highly recalcitrant, polycyclic aromatic hydrocarbon (PAH) with high genotoxicity and carcinogenicity. It is formed and released into the environment due to incomplete combustion of fossil fuel and various anthropogenic activities including cigarette smoke and automobile exhausts. The aim of present study is to isolate bacteria which can degrade BaP as a sole source of carbon and energy. We have isolated a novel strain BMT4i (MTCC 9447) of Bacillus subtilis from automobile contaminated soil using BaP (50 µg /ml) as the sole source of carbon and energy in basal salt mineral (BSM) medium. The growth kinetics of BMT4i was studied using CFU method which revealed that BMT4i is able to survive in BaP-BSM medium up to 40 days attaining its peak growth (1029 fold increase in cell number) on 7 days of incubation. The BaP degradation kinetics of BMT4i was studied using High Performance Liquid Chromatography (HPLC) analysis of BaP biodegradation products. BMT4i started degrading BaP after 24 hours and continued up to 28 days achieving maximum degradation of approximately 84.66 %. The above findings inferred that BMT4i is a very efficient degrader of BaP. To our best of knowledge, this is the first report showing utilization of BaP as a sole source of carbon and energy by bacteria. In addition, BMT4i can degrade a wide range of PAHs including naphthalene, anthracene, and dibenzothiophene therefore, it could serve as a better candidate for bioremediation of PAHs contaminated sites.

Oxidative Desulfurization of Fuel Oil by Pyridinium-Based Ionic Liquids
Author(s) : Dishun Zhao; Yanan Wang; Erhong Duan;
Author Address : School of Chemical Engineering, Tianjin University, Tianjin, 300072, China
Source : Molecules ; Vol.14 No.11 Nov 2009 [Page 4351-4357]
Keyword(s) : ionic liquids; extraction-oxidation; desulfurization; pyridinium-based;
Abstract : In this work, an N-butyl-pyridinium-based ionic liquid [BPy]BF4 was prepared. The effect of extraction desulfurization on model oil with thiophene and dibenzothiophene (DBT) was investigated. Ionic liquids and hydrogen peroxide (30%) were tested in extraction-oxidation desulfurization of model oil. The results show that the ionic liquid [BPy]BF4 has a better desulfurization effect. The best technological conditions are: V(IL)/V(Oil) /V(H2O2) = 1:1:0.4, temperature 55 °C, the time 30 min. The ratio of desulfurization to thiophene and DBT reached 78.5% and 84.3% respectively, which is much higher than extraction desulfurization with simple ionic liquids. Under these conditions, the effect of desulfurization on gasoline was also investigated. The used ionic liquids can be recycled up to four times after regeneration.

Abstract : With the aim of studying the functionalities of hydrodesulfurization (HDS) catalysts, a series of PtMo/g-Al2O3-B2O3 catalysts wit different concentrations of Mo and B were prepared and tested in naphthalene hidrodesaromatization HDA, under H2S atmosphere, and dibenzothiophene (DBT) hydrodesulfurization reactions. It was observed that under the typical conditions of hydrotreatment processes, these catalysts present a poor HDA performance, as well as they display a high selectivity to the direct desulfurization reaction route of DBT hydrodesulfurization. An analysis of the catalytic behavior of the PtMo system in both reactions agrees well with the hypothesis of the existence of independent Pt and MoS2 active phases, where Pt is considered to act as both promoter and as an active center.

Abstract : Desulphurization process by adsorption was studied employing a commercial diesel dooped with 1000 mg/L of benzothiophene and dibenzothiophene. The adsorbents materials employed were three types of activated alumina (acid, basic and neutral). For comparison, adsorption process was made also using oxidized diesel sample. The results showed that the adsorbents were selective for sulphur compounds removal from fuels. The contact time have influence in adsorption process achieving 80% of removal for not oxidized dibenzothiophene. The three studied alumina types showed similar behavior and a greater selective in dibenzothiophene adsorption than benzothiophene. dibenzothiophene removal is more effective in samples not oxidized, whereas the benzothiophene was almost totally removed in oxidized sample.

The Web is repository for an enormous number of desulfurization related documents. Much of the most useful content, however, resides behind fee based portals like ScienceDirect and Ebsco Academic, to name two.
Openj-gate (www.openj-gate.com ) is an exception to this …
Try it out by searching for "dibenzothiophene." Using the advanced search feature, you can restrict the results to a date range, such as 2009-2010.
The results of the search appear below. In each case, a free full text version of the cited article is available for download.
Openj-gate is not a huge repository, and many of the articles are written in languages other than English, which can be a problem for those of us with limited language skills. But it is worth bookmarking for occasional use to supplement your searches in other databases.

Degradation of Benzo [a] Pyrene by a novel strain Bacillus subtilis BMT4i (MTCC 9447)
Author(s) : Lily, Madhuri Kaushish; Bahuguna, Ashutosh; Dangwal, Koushalya; Garg, Veena;
Source : Brazilian Journal of Microbiology ; Vol.40 No.4 Dec 2009 [Page 884-892]
Keyword(s) : Benzo [a] Pyrene (BaP); polycyclic aromatic hydrocarbon (PAH); Bacillus subtilis BMT4i; colony forming units/ml (CFU/ml); high performance liquid chromatography (HPLC).;
Abstract : Benzo [a] Pyrene (BaP) is a highly recalcitrant, polycyclic aromatic hydrocarbon (PAH) with high genotoxicity and carcinogenicity. It is formed and released into the environment due to incomplete combustion of fossil fuel and various anthropogenic activities including cigarette smoke and automobile exhausts. The aim of present study is to isolate bacteria which can degrade BaP as a sole source of carbon and energy. We have isolated a novel strain BMT4i (MTCC 9447) of Bacillus subtilis from automobile contaminated soil using BaP (50 µg /ml) as the sole source of carbon and energy in basal salt mineral (BSM) medium. The growth kinetics of BMT4i was studied using CFU method which revealed that BMT4i is able to survive in BaP-BSM medium up to 40 days attaining its peak growth (1029 fold increase in cell number) on 7 days of incubation. The BaP degradation kinetics of BMT4i was studied using High Performance Liquid Chromatography (HPLC) analysis of BaP biodegradation products. BMT4i started degrading BaP after 24 hours and continued up to 28 days achieving maximum degradation of approximately 84.66 %. The above findings inferred that BMT4i is a very efficient degrader of BaP. To our best of knowledge, this is the first report showing utilization of BaP as a sole source of carbon and energy by bacteria. In addition, BMT4i can degrade a wide range of PAHs including naphthalene, anthracene, and dibenzothiophene therefore, it could serve as a better candidate for bioremediation of PAHs contaminated sites.

Oxidative Desulfurization of Fuel Oil by Pyridinium-Based Ionic Liquids
Author(s) : Dishun Zhao; Yanan Wang; Erhong Duan;
Author Address : School of Chemical Engineering, Tianjin University, Tianjin, 300072, China
Source : Molecules ; Vol.14 No.11 Nov 2009 [Page 4351-4357]
Keyword(s) : ionic liquids; extraction-oxidation; desulfurization; pyridinium-based;
Abstract : In this work, an N-butyl-pyridinium-based ionic liquid [BPy]BF4 was prepared. The effect of extraction desulfurization on model oil with thiophene and dibenzothiophene (DBT) was investigated. Ionic liquids and hydrogen peroxide (30%) were tested in extraction-oxidation desulfurization of model oil. The results show that the ionic liquid [BPy]BF4 has a better desulfurization effect. The best technological conditions are: V(IL)/V(Oil) /V(H2O2) = 1:1:0.4, temperature 55 °C, the time 30 min. The ratio of desulfurization to thiophene and DBT reached 78.5% and 84.3% respectively, which is much higher than extraction desulfurization with simple ionic liquids. Under these conditions, the effect of desulfurization on gasoline was also investigated. The used ionic liquids can be recycled up to four times after regeneration.

Keyword(s) : PtMo; Boron; hydrodesulfurization; desulfurization reaction routes; catalysts.;
Abstract : With the aim of studying the functionalities of hydrodesulfurization (HDS) catalysts, a series of PtMo/g-Al2O3-B2O3 catalysts wit different concentrations of Mo and B were prepared and tested in naphthalene hidrodesaromatization HDA, under H2S atmosphere, and dibenzothiophene (DBT) hydrodesulfurization reactions. It was observed that under the typical conditions of hydrotreatment processes, these catalysts present a poor HDA performance, as well as they display a high selectivity to the direct desulfurization reaction route of DBT hydrodesulfurization. An analysis of the catalytic behavior of the PtMo system in both reactions agrees well with the hypothesis of the existence of independent Pt and MoS2 active phases, where Pt is considered to act as both promoter and as an active center.

Abstract : Desulphurization process by adsorption was studied employing a commercial diesel dooped with 1000 mg/L of benzothiophene and dibenzothiophene. The adsorbents materials employed were three types of activated alumina (acid, basic and neutral). For comparison, adsorption process was made also using oxidized diesel sample. The results showed that the adsorbents were selective for sulphur compounds removal from fuels. The contact time have influence in adsorption process achieving 80% of removal for not oxidized dibenzothiophene. The three studied alumina types showed similar behavior and a greater selective in dibenzothiophene adsorption than benzothiophene. dibenzothiophene removal is more effective in samples not oxidized, whereas the benzothiophene was almost totally removed in oxidized sample.

Google Tip: Translation Tool
"In Taiwan, the translation of the Pepsi slogan “Come alive with the Pepsi Generation” came out as “Pepsi will bring your ancestors back from the dead.” -- http://www.goodquotes.info
Google® offers a free translation gadget you can add to your iGoogle homepage. The translations are not always perfect, but can be useful nonetheless.
For example, let’s say you wanted to Google® for Arabic language resources pertaining to “dibenzothiophene.” Type “dibenzothiophene “ in the translation box. Select “English” in the source language box, and “Arabic” in the other box. Then click “Translate.”
You will find no translation of the word “dibenzothiophene.” Too bad.
But, repeat the search using the word “thiophene,” and you will see a translation in Arabic script.
Next, select the Arabic translation with your cursor, copy to your clipboard, and paste into the Google® search box. The result is several hundred Arabic language items containing that word.
I am not fluent in Arabic, unfortunately. But if you are, this is an easy way for you to search the Web for items of interest to you.

Abstract:
A continuous process to upgrade heavy crude oil for producing more valuable crude feedstock having high API gravity, low asphaltene content, and high middle distillate yield, low sulfur content, low nitrogen content, and low metal co teat without external supply of hydrogen and/or catalyst. Heavy crude oil having substantial amount of asphaltene and heavy components is mixed with highly waxy crude oil having large amount of paraffinic components and water to decompose asphaltene compounds and remove sulfur, nitrogen, and metal containing substances under supercritical conditions. Product has higher API gravity, lower asphaltene content, high middle distillate yield, lower sulfur content, lower nitrogen content, and lower metal content to be suitable for conventional petroleum refining process.

The Great Thing About the Web Is … It’s Free!
“I know but one freedom and that is the freedom of the mind.” -- Antoine de Saint-Exupery quotes (French Pilot, Writer and Author of 'The Little Prince', 1900-1944)
The Great Thing About the Web Is … It’s Free! Of course, freedom comes at a price. And when it comes to actually finding something on the Web, that price is measured in time. That said, sometimes good things just fall into your lap, as did the item below. I was searching for something else when I found it, but I recognized its value when I saw it. Maybe it will be useful to you, as well.
Beyond Ultra Low Sulphur Diesel (ULSD): Technology Enhancements to Improve Distillate Product Quality

Highly technical, but worth the effort because of its explanation of already commercialized desulfurization approaches. One technology described is …
Selective Ring Opening (SRO)
“The objective of SRO is to provide three things: an upgraded diesel product quality (density, aromatics, cetane), a distillate selective reaction pathway and a minimum hydrogen consumption alternative. By delivering on all three of these benefits, SRO provides a very economically attractive upgrading route. Similar to aromatic saturation discussed previously, the SRO chemistry is enhanced by the clean nature of the ULSD product. Catalyst acidity is carefully controlled to avoid full hydrocracking that would result in yield shift to naphtha. Like EAS, the SRO catalysis can occur in a single stage reactor system since base metal reaction promoters are typically used. The multi-functional catalysts used in the SRO system permit some naphthenic molecules to “exit” the reversible aromatic saturation loop (Figure 2), increasing the overall conversion, particularly in operating regimes that can be limited by thermodynamic equilibrium. Thus, the SRO catalyst systems can deliver comparable cetane at reduced hydrogen consumption (Figure 5), and are less sensitive to EOR conditions where hydrogenation conditions deteriorate.”
Here is the abstract of the paper …
ABSTRACT
“With the initial wave of ULSD production well established in many areas of the world, attention has turned toward maximizing the use of these new assets as well as looking forward to anticipate future requirements. The ULSD platform is ideal for providing the opportunity to further upgrade diesel quality, since the chemistry/catalysis for cetane improvement, aromatics reduction, cold flow improvement, density reduction, biodiesel processing and conversion can be achieved by applying the right catalyst and process system. Criterion and Shell Global Solutions will discuss a range of commercially proven options for customers to achieve one or more of these additional diesel-upgrading objectives via simple catalyst changes all the way to new unit designs. These solutions can significantly improve overall refinery economics by leveraging this critical ULSD asset, providing flexibility to upgrade heavier feeds to make more diesel, maximize Light Cycle Oil (LCO) into the on-road diesel pool, provide capability to process more difficult crude, and make products to export into higher values markets.”

The Great Thing About the Web Is … It’s Free! Of course, freedom comes at a price. And when it comes to actually finding something on the Web, that price is measured in time. That said, sometimes good things just fall into your lap, as did the item below. I was searching for something else when I found it, but I recognized its value when I saw it. Maybe it will be useful to you, as well.

Highly technical, but worth the effort because of its explanation of already commercialized desulfurization approaches. One technology described is …
Selective Ring Opening (SRO)
“The objective of SRO is to provide three things: an upgraded diesel product quality (density, aromatics, cetane), a distillate selective reaction pathway and a minimum hydrogen consumption alternative. By delivering on all three of these benefits, SRO provides a very economically attractive upgrading route. Similar to aromatic saturation discussed previously, the SRO chemistry is enhanced by the clean nature of the ULSD product. Catalyst acidity is carefully controlled to avoid full hydrocracking that would result in yield shift to naphtha. Like EAS, the SRO catalysis can occur in a single stage reactor system since base metal reaction promoters are typically used. The multi-functional catalysts used in the SRO system permit some naphthenic molecules to “exit” the reversible aromatic saturation loop (Figure 2), increasing the overall conversion, particularly in operating regimes that can be limited by thermodynamic equilibrium. Thus, the SRO catalyst systems can deliver comparable cetane at reduced hydrogen consumption (Figure 5), and are less sensitive to EOR conditions where hydrogenation conditions deteriorate.”
Here is the abstract of the paper …
ABSTRACT
“With the initial wave of ULSD production well established in many areas of the world, attention has turned toward maximizing the use of these new assets as well as looking forward to anticipate future requirements. The ULSD platform is ideal for providing the opportunity to further upgrade diesel quality, since the chemistry/catalysis for cetane improvement, aromatics reduction, cold flow improvement, density reduction, biodiesel processing and conversion can be achieved by applying the right catalyst and process system. Criterion and Shell Global Solutions will discuss a range of commercially proven options for customers to achieve one or more of these additional diesel-upgrading objectives via simple catalyst changes all the way to new unit designs. These solutions can significantly improve overall refinery economics by leveraging this critical ULSD asset, providing flexibility to upgrade heavier feeds to make more diesel, maximize Light Cycle Oil (LCO) into the on-road diesel pool, provide capability to process more difficult crude, and make products to export into higher values markets.”

Abstract
“New regulations aim to achieve a drastic sulfur emission reduction in fuels and impose very low sulfur concentration caps (30 ppm in gasoline and 15 ppm in diesel) that will be in full force in 2009. FCC gasoline represents almost 40% of the total gasoline pool and it is the major sulfur contributor, with up to 85–95%. To deal with this situation, most refiners have adopted post-treating FCC gasoline processes given they are more viable and less costly for meeting sulfur environmental regulation limits. In this respect, one should notice that conventional hydro-treating of FCC gasoline removes sulfur decreasing gasoline quality with octane number losses. The use of hydrogen also adds important costs to the desulfurization. As a result, new promising catalytic desulfurization processes are being proposed using zeolites as adsorbents/catalysts. These new approaches may lead to novel technologies, for example, with the case of gasoline de-hydrosulfidation with no hydrogen addition and alternatively to adsorption processes with co-feeding of an H-donor being pioneered at CREC University of Western Ontario. In both approaches sulfur is efficiently removed leaving the gasoline octane number index intact. The zeolite structure, the framework composition and the properties of the charge compensating cations are all parameters with major impact on catalytic desulfurization. In particular, shape selectivity is expected to play an important role in determining product selectivity when condensation reactions are significant. In this respect, the H-ZSM5 zeolite appears to have the adequate balance of Brönsted acidity and Lewis basicity to efficiently convert thiophene to H2S, with minimal transformation of benzothiophene and oligomers into coke. From a chemical reactor engineering point of view, novel gasoline desulfurization can be implemented using both fixed and fluidized bed reactors. Fluidized circulating bed reactors display high sulfur removal ability allowing frequent catalyst removal from the catalytic bed and coke combustion in a twin fluidized regeneration unit. Fixed bed units with adsorption/desorption cycles, used in conjunction with and without H donor co-reactants, lead to selective adsorption and efficient removal of sulfur species.”
We refine petroleum to extract useful products for a wide range of end uses. Likewise, we can extract useful information from the refining literature for a number of purposes beyond the obvious.

News you can use: The Catalyst Review Newsletter
“You Don't Have To Be a Rocket Scientist ... To Think Like One” -- George (Pinky) Nelson, research astronomer and director of project 2061, a nationwide science, mathematics and technology initiative of the American Association for the Advancement of Science. He flew three space shuttle missions from 1978 to 1989 while a NASA astronaut
The Catalyst Review Newsletter (http://www.catalystgrp.com/catalystreview.html) contains both news about companies producing catalysts and full length articles on catalyst applications. Although desulfurization is not its focus, since catalysis lies at the heart of desulfurization technology, it is worth browsing for useful nuggets.
And occasionally it contains information targeting desulfurization specifically. For example, the May 2008 issue featured an article titled "Catalysts for Heavy Oil Conversion.”
Here are a couple of excerpts from the article …
“The choice of a catalyst-based process and the properties of the catalyst are determined to a great extent by the product distribution required. A particular feature of the hydroprocessing heavy oil, as compared with its alternatives, is its flexibility with respect to product production and the relatively high quality of the products. On the whole, hydroprocessing can handle a wider range of feedstock than catalytic cracking, although the latter process has seen some recent catalyst developments that narrowed the gap.
“However, proper selection of the types of catalysts to be employed in hydroprocessing heavy oil is essential if the process is to function efficiently. In this respect, mild hydrotreating (which is essentially hydrogen addition prior to conversion and which might be the first stage of the two-stage hydrocracking process, Figure 1) rather than immediate conversion of the heavy feedstock is often selected as a preliminary step prior to fluid catalytic cracking as a means of ultimately increasing conversion of heavy oil into lower boiling higher value products (Figure 2) (Speight, 2000, 2004)."
…
“It appears necessary to develop better analytical methods for the characterization of heavy feeds to be able to better predict the behavior of catalysts and catalytic reactors when processing such feeds.”
