A low coke, high octane, high activity, high selectivity, metal tolerant, thermally stable, low slurry oil producing catalyst is described for the conversion of feed hydrocarbons containing normal paraffins and contaminated with carbon and metals to produce lower molecular weight products. The catalyst consists of: (a) from about 8 to about 25% by weight of a zeolite comprising HY zeolite, having a silica-alumina mole ratio of at least about 5, and having a cell dimension of about 24.30 to about 24.70 angstroms; (b) from about 20 to about 70 wt% of a clay comprising kaolin, having a crystallite size of from about 0.5 to about 2 microns; (c) from about 35 to about 70% of an acidic silica-alumina co-gel matrix comprising at least about 13 wt% alumina; (d) from about 0.1 to about 3 wt% of rare earths comprising lanthanum and cerium in a ratio of from about 1 to about 6; (e) from about 15 to about 60 wt% alumina; (f) wherein the zeolite is partially exchanged with the rare earths from a solution and wherein the zeolite is contained in the acidic matrix and wherein a portion of the rare earths has been precipitated into the matrix; and (g) a catalyst component incorporating a sufficient amount of ZSM-5 zeolite to crack at least a portion of normal paraffins present in the feed.
