A process for converting a feedstock comprising hydrocarbon compounds to conversion products comprising hydrocarbon compounds of lower molecular weight than feedstock hydrocarbon compounds which comprises contacting said feedstock at conversion conditions with a catalyst comprising a zeolite material prepared by a method comprising calcining a crystalline zeolite material having an initial silica:alumina mole ratio of at least about 100:1, said crystalline material having been synthesized from a reaction mixture containing quaternary onium ions, contacting said calcined crystalline material with aluminum chloride vapor at a temperature of from about 100.degree. C. to about 600.degree. C., hydrolyzing said aluminum chloride contacted crystalline material and calcining said hydrolyzed crystalline material.
A process for converting a feedstock comprising hydrocarbon compounds to conversion products comprising hydrocarbon compounds of lower molecular weight than feedstock hydrocarbon compounds which comprises contacting said feedstock at conversion conditions with a catalyst comprising a zeolite material prepared by a method comprising calcining a crystalline zeolite material having an initial silica:alumina mole ratio of at least about 100:1 and the structure of zeolite ZSM-5, said crystalline material having been synthesized from a reaction mixture containing quaternary onium ions, contacting said calcined crystalline material with aluminum chloride vapor at a temperature of from about 100.degree. C. to about 600.degree. C., hydrolyzing said aluminum chloride contacted crystalline material and calcining said hydrolyzed crystalline material.
