Passivation of metals which contaminate cracking catalysts with antimony tris (hydrocarbyl sulfonate)

摘要

A hydrocarbon oil cracking process in which a cracking catalyst employed has been treated with a passivating amount of an antimony tris (hydrocarbyl sulfonate), e.g., antimony tris (p-toluene sulfonate). The catalyst can be a conventional cracking catalyst, e.g., silica/alumina, zeolite, etc. The application can be conducted before and/or after the catalyst has been used to crack a hydrocarbon.
