ABSTRACT:
A process for making an improved zeolite catalyst composition comprising acid-treating a zeolite to provide an acid-treated zeolite, ion-exchanging the ions of such acid-treated zeolite with ions of zinc and at least one other metal in the presence of an ion-exchange medium, and then treating such acid-treated, ion-exchanged zeolite in a steam atmosphere. An improved zeolite catalyst composition made by such process is also disclosed. Processes are also disclosed for using the improved zeolite catalyst composition, made by the novel process, in the conversion of hydrocarbons, preferably non-aromatic hydrocarbons, to lower olefins (such as ethylene and propylene) and aromatic hydrocarbons (such as benzene, toluene, and xylene).
