Biodesulfurization And Desulphurization Of Itakpe

Biodesulfurization draws attention because of its special inorganic and organic sulfur removal ability. 8, 9 There are some desulfurizing bacteria, both organosulfur and inorganosulfur, discovered to be used in coal biodegradation. Examples of inorganosulfur bacteria such as Acidithiobacillus caldus, Acidithiobacillus ferrooxidans, Acidithiobacillus thiooxidans 1012 and examples of ...

Introduction dered by substitutions in positions 4 and 6 are the most di⁄cult to remove by hydrodesulfurization (HDS) and Combustion of petroleum derived fuels leads to the at 4,6dimethyldibenzothiophene (4,6DMDBT) has been mospheric emission of sulfur oxides which are the .

Biodesulfurization. Biodesulfurization is an alternative to the current hydrotreater. While other alternatives to hydrotreaters are under development to desulfurize various refinery products, biodesulfurization would be a complete breakthrough in process development. It would offer mild processing conditions and reduce the need for hydrogen makeup. . Both would lead to high energy .

the desulphurization process. The integration of these two processes would outcome the economic and ecofriendly fuel supply. Role of Surfactants in Biodesulphurization Since the bacteria reside in the water phase and the organosulfur compounds dissolve in organic phase, the biodesulfurization reactions occur at the interface. Therefore,

Combined desulphurization technologies are being studied, including bioprocessing to upgrade fossil fuels. Using biodesulphurization (BDS), which is a biochemical process mediated by specific microorganisms, it is possible to desulphurize most of the hydrodesulphurization (HDS) recalcitrant sulphur compounds under mild operating conditions ...

Desulfurization or desulphurisation is a chemical process for the removal of sulfur from a material. This involves either the removal of sulfur from a molecule ( A=S → A:) or the removal of sulfur compounds from a mixture such as oil refinery processes are of great industrial and environmental importance as they provide the bulk of sulfur used in industry (Claus process and ...

Jan 26, 2005 · Aims: To study the desulphurization of dibenzothiophene (DBT), a recalcitrant thiophenic component of fossil fuels, by two bacteria namely Rhodococcus sp. and Arthrobacter sulfureus isolated from oilcontaminated soil/sludge in order to use them for reducing the sulphur content of diesel oil in compliance with environmental regulations. Methods and Results: The desulphurization pathway of .

 · Biodesulfurization of diesel has been studied in airlift bioreactors (Nandi, 2010, Irani et al., 2011). Amin (2011) used an integrated twostage process for biodesulfurization of a model oil using a vertical rotating immobilized cell reactor with the bacterium R. erythropolis.

This paper studies the appliion of desulfurization additives in the desulfurization system for 600MW units, Results show that desulfurization additives have a positive effect on the desulphurization efficiency, and it can gain notable economic benefits when it guarantees the effective concentration of the desulfurization additives and the ...

Jan 01, 2005 · In order to study desulphurization of diesel oils obtained from an oil refinery, resting cell studies were carried out which showed a decrease of about 50% in sulphur content of the oil obtained from the hydrodesulphurization (HDS) unit of the refinery. Conclusions Rhodococcus sp. and A. sulfureus selectively remove sulphur from DBT to form 2HBP.

May 01, 2006 · Biodesulfurization of gasoline. Biodesulfurization of gasoline was carried out under the volumetric phase ratio of aqueous to oil as nine (total volume was 100 mL) and shaken for 12 h at 30°C in a 4 L sealcapped bottle to supply enough oxygen. The bottle was cooled at 4°C for 1 h to prevent volatilization of gasoline before sampling.

 · For this reason, alternative technologies such as oxidative desulfurization, extractive desulfurization, biodesulfurization and adsorptive desulfurization are studied. Among these, adsorptive desulfurization (ADS) represents a promising alternative method of removing sulfur by adsorption under ambient conditions. The lifetime, selectivity and capacity of ADS highly depend on the type of ...

Oxidative Desulfurization, Biodesulfurization, Liquid Phase, Catalysis, Clean Fuels, Selective Oxidation 1 Introduction Liquid fuels contain a large variety of sulfur compounds (thiols, sulfides, disulfides and thiophenes), which generate SO 2 and airborne particulate emissions during combustion. Therefore, desulfurization of light oil is extremely important in the petroleumprocessing ...

Jun 24, 2010 · Most of the effective coal desulfurization techniques are based on chemical methods. Main desulfurization methods are chemical desulfurization, leaching, extraction, flotation, oxydesulfurization and biodesulfurization.
