Process for the catalytic cracking of metals-containing feedstocks
Patent
·
OSTI ID:5648895
A process is described for the catalytic cracking of a metals-containing hydrocarbon feedstock which comprises contacting the hydrocarbon feedstock with a cracking catalyst under cracking conditions in the substantial absence of added molecular hydrogen in a cracking zone to convert components of the feedstock into lower molecular weight constituents, wherein the cracking catalyst comprises (1) a porous, inorganic refractory oxide component in combination with (2) a dealuminated Y zeolite having a silica-to-alumina mole ratio greater than about 6.0, the zeolite having been prepared by contacting a Y zeolite with an aqueous solution of a fluorosilicate salt.
