Abstract

Self-heating characteristics of a spontaneously combustible catalyst are reduced by treating the catalyst with an oxygen-containing hydrocarbon having at least 12 carbon atoms. The treatment is particularly suitable for reducing the self-heating characteristics of sulfidable metal oxide(s)-containing catalysts, presulfurized catalysts, presulfided catalysts or induced catalysts. When applied to sulfur-containing catalysts, the treatment gives a catalyst that has suppressed self-heating properties without substantially compromising sulfur retention or activity. Further hydrocracking catalysts treated by the oxygen-containing hydrocarbons give improved product yield. Further, a method of safety unloading a catalyst from a reactor is provided where the catalyst in the reactor is treated with a liquid mixture containing the oxygen-containing hydrocarbon to wet the catalyst.
