Metal-tolerant FCC catalyst and process

摘要

A metals-tolerant FCC catalyst and a process using the catalyst are disclosed. The catalyst matrix comprises bastnaesite and a limited quantity of a large pore boehmite alumina having an average pore diameter greater than 90 Angstroms. The catalyst preferably also contains a molecular sieve component, a siliceous binder and a clay component. The catalyst formulation reduces the harmful effects of accumulated nickel and vanadium on catalyst activity and selectivity. Hydrogen and coke production are reduced.
