Abstract
Hydrocarbon feeds are treated to remove sulfur, nitrogen, oxygen, metals and/or other impurities by contact with treating gas comprising carbon monoxide and water under reaction conditions in the presence of catalysts having shift and hydrogenating activity as well as improved steam stability. The catalysts comprise (1) a metallic component having shift and hydrogenating activity, (2) a support component comprising activated alumina and (3) a steam stabilizing phosphorus component.

A process for treating hydrocarbon feeds to remove contaminants comprising sulfur, nitrogen, oxygen, metals or combinations thereof comprising contacting the feed and a treating gas comprising water and carbon monoxide under reaction conditions in the presence of a catalyst comprising (1) a metallic component having shift and hydrogenating activity, (2) a support component comprising activated alumina and (3) a steam-stabilizing phosphorus component.
A process for desulfurization of hydrocarbon feeds containing at least about 1.5 wt% sulfur comprising contacting the feed with treating gas comprising hydrogen, steam and carbon monoxide wherein the molar ratio of steam to carbon monoxide is greater than about 1:1, such treating gas being present in an amount effective to provide a hydrogen addition rate of about 350 to about 8000 SCFB, of which at least 20 vol% is provided by reaction of said water and carbon monoxide, at a temperature of about 600.degree. to about 800.degree. F., pressure of about 200 to about 2500 psig and space velocity of about 0.2 to about 8 lb/lb/hr in the presence of a catalyst comprising (1) a metallic component comprising nickel having shift and hydrogenating activity, (2) a support component comprising activated alumina and (3) a steam-stabilizing phosphorus component.
