Microbial Biodesulfurization Of Dibenzo-Thiophene In Egyptian Petroleum Crude Oil
MEOR - Microbial Enhanced Oil Recovery - is a hot topic in desulfurization. We ran across the following article in a recent search ...
Microbial Biodesulfurization Of Dibenzo-Thiophene In Egyptian Petroleum Crude Oil (2009)
Biodesulfurization has been studied as an alternative to HDS for removal of organic sulfur from fuels. The use of hydrocarbon degradation pathways that attacked DBT was unsuccessful because these systems relied on the oxidation and mineralization of the carbon skeleton instead of sulfur removal. Therefore, it significantly reduced the fuel value of the desulfurized end product. More recently, bacteria that desulfurize DBT and a variety of other organic sulfur compounds typically found in petroleum oils via a sulfur selective oxidative pathway that does not remove carbon have been isolated. This pathway involves the sequentional oxidation of the sulfur moiety followed by cleavage of the carbon sulfur bonds (Monticello et al., 1985; Grossman, 1996).
This study aims to isolate, purify and identify some microorganisms that have the ability to degrade DBT and fossil fuelbiodesulfurization (sulfur removal) without concomitant metabolism of hydrocarbon value of the fuel. In this study we describe of the microbial desulfurization of DBT by two yeast isolates under the best culture conditions and its application. The possibility of using these isolates for application was discussed.

A kinetic study on biodesulfurization of di-benzothiophene in a downflow jet loop
Iran gets a lot of bad press in the U.S., but some interesting research is coming out of that country. Example …
A kinetic study on biodesulfurization of di-benzothiophene in a downflow jet loop (Iran)(2008)
19th World Petroleum Conference, Spain 2008
Forum 09: Latest advances and novel processes for deep desulfurization
From the Introduction
"Some organic sulfur compounds can only be eliminated by biological methods. Microbial desulfurization may be carried out both aerobically and anaerobically. In this study, anaerobic bacteria have been applied. In the presence of either hydrogen or nitrogen gases the sulfur organic compounds are reduced by the anaerobic bacteria. The products of reactions are H2S gas and organic compounds free from sulfur. One of the advantages of anerobic desulfurization is that no loss in the amount of oil is encountered by application of such processes. In addition, these reactions are more compatible with conventional hydrodesulfurization process applied in industry.
"In this study desulfurization of DBT (di-benzothiophene) by D. desulfuricans in an anaerobic jar without injection of hydrogen has been investigated. In addition, such a process has been conducted in a DJR (down flow jet loop bioreactor) system, with the injection of hydrogen.
"The results obtained from this study have been compared with those determined under different reaction methods."

Wikipedia Revisited
Skepticism abounds regarding the reliability of the information available on Wikipedia. Still, we have found it to be a useful resource. Take, for example, the case of MEOR - Microbial Enhanced Oil Recovery.
If you are an expert in the field, the table listing the major ventures working MEOR can be useful.
If you are new to the field, the survey of areas of application, problems to be addressed, advantages and disadvantages, etc., can be helpful.
Here are some excerpts from the Wikipedia article on MEOR …
Ventures working in MEOR (Private sector)
Rawwater Engineering Company Ltd
Oppenheimer Biotechnology, Inc.
Titan Oil Recovery, Inc.
Yara International ASA
Circle T Sales and Service Inc.
GloriOil Ltd.
StatoilHydro ASA
Environmental BioTechnologies, Inc.
ONGC-IRS
Rogaland Research
COREC
CIPR
"Several decades of research and successful applications support the claims of MEOR as a mature technology. Despite those facts, disagreement still exists. Successful stories are specific for each MEOR field application, and published information regarding supportive economical advantages is however inexistent. Despite this, there is consensus considering MEOR one of the cheapest existing EOR methods.
“MEOR advantages
“• Injected microbes and nutrients are cheap; easy to handle in the field and independent of oil prices. • Economically attractive for mature oil fields before abandonment. • Increases oil production. • Existing facilities require slight modifications. • Easy application. • Less expensive set up. • Low energy input requirement for microbes to produce MEOR agents. • More efficient than other EOR methods when applied to carbonate oil reservoirs. • Microbial activity increases with microbial growth. This is opposite to the case of other EOR additives in time and distance. • Cellular products are biodegradable and therefore can be considered environmentally friendly.
“MEOR disadvantages
“• The oxygen deployed in aerobic MEOR can act as corrosive agent on non-resistant topside equipment and down-hole piping
“• Anaerobic MEOR requires large amounts of sugar limiting its applicability in offshore platforms due to logistical problems
“• Exogenous microbes require facilities for their cultivation.
“• Indigenous microbes need a standardized framework for evaluating microbial activity, e.g. specialized coring and sampling techniques.
"• Microbial growth is favoured when: layer permeability is greater than 50 md; reservoir temperature is inferior to 80 0C, salinity is below 150 g/L and reservoir depth is less than 2400m.”

Energy & Environmental Science
We have run across desulfurization items authored or co-authored by Chunshan Song in the past, so when the following article turned up in our search results, we took a closer look. Here is the cite, with brief description extracted from the article.
Energy Environ. Sci., 2009, 2, 878-882
Nanoporous molecular basket sorbent for NO2 and SO2 capture based on a polyethylene glycol-loaded mesoporous molecular sieve
Xiaoxing Wang, Xiaoliang Ma, Shuqi Zhao, Bei Wang and Chunshan Song *
Clean Fuels and Catalysis Program, EMS Energy Institute, Department of Energy & Mineral Engineering, The Pennsylvania State University, 209 Academic Projects Building, University Park, PA 16802, USA. E-mail: csong@psu.edu ; Fax: +1 814 865 3573; Tel: +1 814 863 4466
“Removal of environmentally harmful NO2 and SO2 from various gas streams is important for the protection of human health and the environment, for CO2 capture and sequestration (CCS) and for energy-efficient fuel cell applications. Although there are commercial technologies such as flue gas desulphurization (FGD) for SO2 removal and selective catalytic reduction (SCR) for NO2 removal, alternative and more environmentally benign methods based on solid sorbents with better energy efficiency and easier handling are highly desirable. The present work aims at a new approach based on a polymer-based solid sorbent for removing toxic NO2 and SO2 at room temperature under atmospheric pressure without using catalyst and without involving chemical reactions. We have developed a novel type of nano-porous molecular basket sorbent (MBS) based on polyethylene glycol (PEG)-loaded mesoporous molecular sieve SBA-15 for removing more than 99% of NO2 and SO2 from gas streams at room temperature and atmospheric pressure. The spent sorbent can be regenerated easily and completely by heating to 100 °C. With this new approach, the present study may open a new window for developing environmentally-friendly high-performance solid sorbents for SO2 and NO2 removal from various gas streams.
