ABSTRACT:
A process is provided for converting feedstock comprising oxygenates to product comprising hydrocarbons over a catalyst comprising a high silica crystalline zeolite which has been treated by steps of calcining the crystalline material, contacting the calcined material with solid aluminum fluoride, and converting the aluminum fluoride contacted material to hydrogen form, such as, for example, by contact with a hydrogen ion precursor, e.g., an ammonium salt solution, and calcination.
