Vanadium passivation in a hydrocarbon catalytic cracking process

Patent ·
OSTI ID:6687183
;
This patent describes a catalyst composition. It comprises: a crystalline aluminosilicate zeolite, a matrix material, and from 5 to 40 weight percent, based on the total catalyst composition, of a vanadium passivator having a passivation factor of at least 2.0, the anion of the vanadium passivator to be of a weak nonvolatile acid having a pKa {gt} 5 and the cation is a Group IIA metal having an atomic number greater than 20.
