Hydrodesulfurization of hydrocarbon oil with a catalyst including titanium oxide

摘要

Hydrocarbon oil containing sulfur compounds, for example, lighter petroleum fraction having a boiling point of not higher than 250 DEG C. is hydrodesulfurized to less than 1 ppm with a hydrogenating gas containing 1 to 40% by volume of oxides of carbon (CO2 and CO) in the presence of a catalyst comprising 3 to 40% by weight of at least one of molybdenum and tungsten, and 2 to 15% by weight of at least one of nickel and cobalt, the balance being titanium oxide. Product gas from steam reforming can be used as the hydrogenating gas.
