Abstract
The present invention relates to a method of improving catalytic activity of a zeolite by first steam treating the zeolite and then loading the zeolite so treated with a Group IIIb metal, especially gallium. It has been found that steam treatment prior to gallium loading gives a catalyst which has a higher conversion and selectivity of hydrocarbon feeds to aromatics than otherwise.
