Passivation of metals contaminating a cracking catalyst with trihydrocarbylantimony oxide and process for converting hydrocarbons

摘要

A cracking catalyst is treated with a trihydrocarbylantimony oxide to passivate contaminating metals whenever these metals have been deposited on the catalyst. Unused or used catalyst can be treated. A process for cracking a hydrocarbon, e.g. hydrocarbon oil, is disclosed.
