A select group of hydrocarbon conversion catalysts suitable for converting carbo-metallic oil containing hydrocarbons to lower boiling transportation fuels are characterized and their method of preparation described. The select catalysts of this invention contain at least one zeolite in high concentration and said zeolite possessing a high silica-alumina ratio and a high lanthanum exchange content dispersed in a matrix possessing high pore volume and large pore size. In addition, the matrix material of large pore size and high pore volume is prepared to provide some acidic cracking activity and contains select metals as the oxide for the immobilization of vanadium and/or select materials for the trapping of deposited metals (Ni, V, Fe, Na) to counteract the detrimental effects of these metals in the regenerator section.
