Oxidation Of Sulfur Compounds

The paper studies the process of oxidative desulphurization of catalytic cracking and coking gasoline types and their close cut fractions. Direct oxidation studies of these gasoline fractions using hydrogen peroxide in the presence of heterogenic catalysts containing Mo and Co ions have been carried out for the oxidation of sulfur compounds and their further extraction via ion fluids enabling extraction of sulfur-organic compounds in the form of concentrates of oily sulfoxides and sulfanoles. Thus, desulfurization degree of gasoline fractions comprises 70-80 % - ultimately without change in gasoline octane number.

Current work is devoted to covalent immobilization of sulfonated derivatives of cobalt phthalocyanines “Merox catalysts” on the surfaces of polypropylene and polyethylene terephthalate. Their catalytic activity in reaction of mild oxidation of sulfur compounds to disulfides with oxygen of the air was studied. Anchoring of the catalyst on this polymer prevents its leaching and promotes its efficient recovering and recycling without significant loss of catalytic activity.
