Process for the catalytic cracking of vandium- containing feedstocks

Patent ·
OSTI ID:7180652
This patent describes a process for the catalytic cracking of a vanadium-containing hydrocarbon feedstock. The process 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. The cracking catalyst comprises: a crystalline aluminosilicate zeolite dispersed in a matrix; and a vanadium passivating agent selected from the group consisting of cerium and neodymium and compounds thereof.
