    Abstract: A zeolite fluid catalytic cracking catalyst is provided that passivates nickel and vanadium during catalytic cracking. The zeolite fluid catalytic cracking catalyst includes Y-faujasite crystallized in-situ from a metakaolin-containing calcined microsphere. The zeolite fluid catalytic cracking catalyst further includes an alumina-containing matrix obtained by calcination of a dispersible crystalline boehmite and a kaolin contained in the metakaolin-containing calcined microsphere, where the dispersible crystalline boehmite has a crystallite size of less than 500 Å. Also provided are a method of reducing contaminant coke and hydrogen yields and a method of catalytic cracking of heavy hydrocarbon feed stocks.
