ABSTRACT:
A catalytic process for converting low molecular weight non-aromatic compounds into higher molecular weight aromatic compounds utilizes a unique zeolite catalyst with improved hydrocarbon conversion. The catalyst is 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 is subjected to thermal or hydrothermal treatments under controlled conditions of temperature, time or steam partial pressure so as to effect a decrease in the amount of carbon deposited as the zeolite catalyst. The catalyst can be used in a process for the conversion of light hydrocarbon feedstocks to improve aromatization activity.
