FCC processing using catalyst compositions containing metal ion-exchanged zeolites |
(57) A zeolite composition comprising a zeolite incorporated within a matrix, which zeolite
contains ions of a metal selected from zinc, titanium, copper, chromium, manganese,
cobalt, gallium, germanium, indium, tin, antimony and iron, and especially zinc, when
used as a catalyst in hydrocarbon cracking, especially FCC, exhibits simultaneously
activity enhancement, enhanced aromatic and branched chain paraffins in the gasoline
fraction and passivation of both nickel and vanadium.
The catalyst composition can be prepared by incorporating a zeolite, especially zeolite
Y, in a matrix material to provide a zeolite composition and thereafter subjecting
the composition to metal ion-exchange.
