Abstract
Abstract Substitution of aluminum or gallium for boron or iron contained in the framework of a high silica content zeolite is effected by treating the zeolite in liquid water in the presence of a compound of aluminum or gallium. Catalyst comprising the treated zeolite is used for conducting acid-catalyzed reactions of organic compounds, e.g. conversion of oxygenates to hydrocarbons.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
104 words
A process for converting feedstock comprising organic compounds selected from the group consisting of alcohol, compound containing a carbonyl group, ether and mixtures thereof to conversion product comprising hydrocarbon compounds which comprises contacting said feedstock at conditions sufficient to convert said feedstick to said product hydrocarbons, with a catalyst composition prepared by a method for substituting aluminum or gallium for boron or iron contained in the robust framework of a high silica content crystalline zeolite, which method comprises hydrothermally treating said zeolite in the presence of a compound of said aluminum or gallium, said hydrothermal treatment being under conditions effective to induce said substitution.
