Abstract
Hydrocarbons containing vanadium are converted to lower boiling fractions employing a zeolitic cracking catalyst containing a significant concentration of a calcium-containing additive as a vanadium passivating agent.
Claims8
A process for the conversion of a hydrocarbon oil feed having a significant concentration of vanadium to lighter oil products which comprises contacting said feed under conversion conditions with a cracking catalyst containing a calcium-containing additive selected from the group consisting of calcium-titanium, calcium-zirconium, calcium-titanium-zirconium oxides and mixtures thereof.
