Abstract

A catalyst nominally containing zeolite, clay and silica-alumina gel. The zeolite is preferably partially exchanged with high La/Ce ratio solution in a wetting step. The catayst and processes for its manufacture and use are disclosed. The catalyst is excellent for processing heavy oils, generally produces higher LCO/slurry oil ratio and has high metals tolerance.
