Abstract
Abstract Desulfurization of a sulfurous hydrocarbon distillate containing mono-olefinic hydrocarbons and aromatics is carried out by reacting the distillate with hydrogen in contact with a catalyst composite of a carrier, a platinum or palladium component, a rhodium component and a tin component. The carrier may be alumina, alumina-boria, silica-alumina, chromia-alumina, alumina-silica-boron phosphate or crystalline aluminosilicate.
