Estimating the term…
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.
A zeolite fluid catalytic cracking catalyst that passivates nickel and vanadium during catalytic cracking, the zeolite fluid catalytic cracking catalyst comprising:
A method of reducing contaminant coke and hydrogen yields, the method comprising passivating, during catalytic cracking, nickel and vanadium with a zeolite fluid catalytic cracking catalyst comprising dispersible crystalline boehmite, wherein the dispersible crystalline boehmite has a crystallite size of less than 500 Å.
A method of catalytic cracking of heavy hydrocarbon feed stocks, the method comprising passivating, during the catalytic cracking, nickel and vanadium with a zeolite fluid catalytic cracking catalyst comprising dispersible crystalline boehmite, wherein the dispersible crystalline boehmite has a crystallite size of less than 500 Å.
