ABSTRACT:
A catalytic cracking catalyst and process which tolerates high levels of vanadium and coke precursors in the feed is disclosed. A zeolite in an alumina free binder or coating, preferably silica, is used as the cracking catalyst. RE-USY in silica is especially preferred as it has a low affinity for vanadium, low coking characteristics and high stability. Preferably a vanadium getter additive is present as separate particles to act as a vanadium sink. The catalyst and process may be used in fluidized bed catalytic cracking (FCC) or in moving bed catalytic cracking units. A method of making a coated catalyst, by adding a layer of an alumina free material to a core of alumina containing cracking catalyst is also disclosed.
