ABSTRACT:
A method for enhancing the activity of high silica zeolites, i.e. having a silica-to-alumina ratio greater than 100 which have been synthesized from a reaction mixture containing tetraalkylammonium ions is disclosed which involves calcining the as synthesized zeolites, treatment of the same with aluminum chloride, followed by hydrolysis and calcination in order to obtain materials having an enhanced activity.
