Abstract
A method for making a catalyst containing a vanadium passivating agent in the form of anatase crystalline TiO.sub.2 including a method for processing hydrocarbon feeds containing vanadium.
Claims5
A process for the cracking of hydrocarbon feeds to light oil products, said hydrocarbon feeds having a vanadium content of at least 1 ppm comprising contacting said hydrocarbon feed under conversion conditions with a cracking catalyst having a matrix selected from the group consisting of silica, silica-alumina, silica-anatase-phosphorus, silica-anatase-sulfate, kaolin, halloysite, montmorillonite and mixtures thereof and a vanadium passivating agent in the form of a stabilized anatase crystalline form of TiO.sub.2 as TiO.sub.2 /P.sub.2 O.sub.5, TiO.sub.2 /SO.sub.4.sup.=, TiO.sub.2 /Nb.sub.2 O.sub.5 and mixtures thereof in an amount of about greater than or equal to 3 wt.% in said final catalyst.
