Estimating the term…
Hydrogen sulfide is removed from a fluid stream by contacting the fluid stream which contains hydrogen sulfide with an absorbing composition comprising zinc, titanium and at least one promoter selected from the group consisting of vanadium, chromium, manganese, iron, cobalt, nickel, molybdenum, rhenium, and compounds thereof. If organic sulfur compounds are present in the fluid stream, the absorbing composition acts as a hydrodesulfurization catalyst to convert the sulfur in the organic sulfur compounds to hydrogen sulfide which is subsequently removed from the fluid stream by the absorbing composition. If olefin contaminants are present in the fluid stream, the absorbing composition acts as hydrogenation catalyst to hydrogenate the olefin contaminants to paraffins.
A process for hydrodesulfurizing an organic sulfur compound contained in a fluid stream to convert the sulfur in the organic sulfur compound to hydrogen sulfide and for removing hydrogen sulfide from the fluid stream comprising the step of contacting said fluid stream under suitable hydrodesulfurization conditions with an incompletely sulfided catalyst/absorbing composition comprising zinc titanate, and at least one promoter selected from the group consisting of vanadium, chromium, manganese, iron, cobalt, nickel, molybdenum, rhenium, and compounds thereof, wherein the concentration by weight of said at least one promoter in said catalyst/absorbing composition is less than the total concentration by weight of said zinc titanate in said catalyst/absorbing composition.
A process for hydrodesulfurizing an organic sulfur compound contained in a fluid stream, which does not contain hydrocarbons which are subject to dehydrogenation, reforming or hydrocracking, to convert the sulfur in the organic sulfur compound to hydrogen sulfide and for removing hydrogen sulfide from the fluid stream comprising the step of contacting said fluid stream under suitable hydrodesulfurization conditions with an incompletely sulfided catalyst/absorbing composition comprising zinc titanate.
