Method of thermocatalytic oxidation and desulfurization of organic compounds containing sulfur

Abstract

The subject of the application is a method for thermocatalytic oxidation and desulfurization of organic compounds containing sulfur, consisting in subjecting them in the gaseous state to complete oxidation with air in a flow reactor, in the presence of a contact catalyst for the oxidation reaction, with the ratio of the volumetric flow rate of the air used in the process to the volumetric flow rate of the air theoretically necessary for complete oxidation of the substrate equal to at least 1.1, with the ratio of the volumetric flow rate of the reaction mixture to the volume of the catalyst equal to 360 - 360000 h -1and a contact time with the catalyst of 0.01 - 10 s, and after the oxidation process, the removal of sulfur adsorbed on the catalyst in the form of its oxides and the removal of the product of complete oxidation of the organic compound into the environment, after neutralizing its acidic components, characterized in that a catalyst containing a noble metal is used, deposited on a support containing a transition metal, containing at least 0.1% by weight of the noble metal. The oxidation process is carried out at a temperature of 300°C - 550°C.
