ABSTRACT:
A zeolite catalyst with improved hydrocarbon conversion comprising a crystalline aluminosilicate having a SiO.sub.2 /Al.sub.2 O.sub.3 ratio greater than 5 and preferably a MFI or MEL zeolite. The zeolite contains a Group VIIIA metal, preferably nickel, and it has been subjected to severe thermal or hydrothermal treatments under controlled conditions of temperature, time or steam partial pressure so as to effect an increase in the relative surface concentrations of Group VIIIA metal and aluminum. The catalyst can be used in a process for the conversion of paraffinic feedstocks to improve paraffin cracking activity, to increase the aromatic fraction in the C5 to C12 gasoline range products, to improve the calculated octane numbers of the C5 to C12 gasoline range product, and/or to improve the yield of the C5 to C12 gasoline range products.
