Abstract
The catalytic hydrodesulfurization of organic compounds containing sulfur is carried out in the presence of a catalyst composition comprising zinc titanate and at least one promoter selected from the group consisting of vanadium, chromium, cobalt, nickel, molybdenum, tungsten, rhenium, platinum, palladium, rhodium, ruthenium, and compounds thereof.
Claims25
A process for the catalytic hydrodesulfurization of an organic sulfur compound comprising the step of contacting said organic sulfur compound under suitable hydrodesulfurization conditions with a catalyst composition comprising zinc, titanium, and at least one promoter selected from the group consisting of vanadium, chromium, cobalt, nickel, molybdenum, tungsten, rhenium, platinum, palladium, rhodium, ruthenium, and compounds thereof, wherein the concentration by weight of said at least one promoter in said catalyst composition is less than the total concentration by weight of said zinc and said titanium in said catalyst composition and wherein said catalyst composition is prepared by calcining a mixture of zinc oxide and titanium dioxide in the presence of molecular oxygen at a temperature in the range of about 650.degree. C. to about 1050.degree. C. to form zinc titanate, adding said at least one promoter to said zinc titanate to form a promoted zinc titanate and completely sulfiding said promoted zinc titanate to form said catalyst composition.
A process for the catalytic hydrodesulfurization of an organic sulfur compound which is contained in a fluid stream which does not contain hydrocarbons which are subject to dehydrogenation, reforming or hydrocracking comprising the step of contacting said fluid stream containing said organic sulfur compound under suitable hydrodesulfurization conditions with a catalyst composition comprising zinc and titanium, wherein said catalyst composition is prepared by calcining a mixture of zinc oxide and titanium dioxide in the presence of molecular oxygen at a temperature in the range of about 650.degree. C. to about 1050.degree. C. to form zinc titanate and completely sulfiding said zinc titanate to form said catalyst composition.
