    OSTI.GOV Technical Report: Enzymatic desulfurization of coal

    Toward that end, a series of specific objectives were defined: 1 establish the feasibility of bio oxidative pretreatment followed by biochemical sulfate cleavage for representative sulfur-containing model compounds and coals using commercially-available enzymes; 2 investigate the potential for the isolation and selective use of enzyme preparations from coal-utilizing microbial systems for desulfurization of sulfur-containing model compounds and coals; and 3 develop a conceptual design ...

    Enzymatic coal desulfurization Patent OSTI.GOV

    Abstract. This patent describes a method for reducing the total sulfur content of a fossil fuel containing organic sulfur. It comprises contacting the fossil fuel with a solution containing sulfatase to release organic sulfur as water-soluble free sulfate; recovering from the solution a fossil fuel having a reduced sulfur content.

    Microbial removal of organic sulfur from coal bacterial ...

    Almost all of the inorganic sulfur can be removed from coal by the bacteria Thiobacillus or Sulfolobus, which convert sulfide to sulfate but leave the organic sulfur untouched. Certain coals, including those in the Illinois Basin, contain high levels of organic sulfur, especially thiophenes; hence, removal of organic sulfur is also necessary.

    SELECTIVE REMOVAL OF ORGANIC SULFUR FROM COAL BY ...

    ABSTRACT. ABSTRACT. Desulfurization of coal involves the removal of both the inorganic and organic forms of sulfur. Several physical methods are available for the removal of inorganic sulfur which is normally represented by pyritic and sulfatic sulfur. Removal of organic sulfur requires the use of chemical cleaning methods.

    Experimental Study on Organic Sulfur Removal in Bituminous ...

    , to remove sulfur in coal at 70−80 C temperature, and obtained 50.20% removal of the total sulfur and 48% of the organic sulfur. Wang et al.25 used 1-butyl-3-methylimidazolium hydrogen sulfate Bmim HSO 4 in combination with 30% H 2 O 2 solution to remove sulfur at ambient temperatures and pressures and significantly reduced
