METHOD FOR CATALYTIC HYDROGENATION OF SILICON-CONTAINING HYDROCARBON SUPPLYING RAW MATERIAL

PROBLEM TO BE SOLVED: To provide a method for catalytic hydrogenation of a silicon-containing hydrocarbon supplying raw material. SOLUTION: The method for catalytic hydrogenation of a silicon compound-containing hydrocarbon supplying raw material comprises a process for bringing the supplying raw material into contact with a first hydrogenation catalyst in the presence of hydrogen at an outlet temperature of up to 410°C to reduce the content of the silicon compound in the supplying raw material, a process for cooling the thus treated supplying raw material to a temperature of 280-350°C, and a process for bringing the cooled supplying raw material into contact with a second hydrogenation catalyst under an effective condition to decrease the concentrations of sulfur compounds and nitrogen compounds, wherein the first hydrogenation catalyst is positioned in at least two serially connected reaction vessels.
