Methanol conversion using reactivated zeolite
A process is described for converting a feedstock comprising organic compounds selected form the group consisting of alcohol, carbonyl, ether and mixtures thereof to conversion product comprising hydrocarbon compounds. The process comprises contacting the feedstock at conversion conditions with a catalyst composition comprising a crystalline zeolite material having a silicon/aluminum atomic ratio of at least about 2. The catalyst composition is deactivated by contact with steam and reactivated by the steps of contacting the steam-deactivated catalyst composition with an aluminum compound vapor at a temperature of from about 100/sup 0/C. to about 850/sup 0/C. and thereafter contacting the aluminum compound contacted catalyst composition with an aqueous acid solution of from about 0.001 molar to about 10 molar at a temperature of from about 20/sup 0/C. to about 100/sup 0/C.
