ABSTRACT:
A method is described for producing a surface modified catalytically active zeolite which method comprises chemically modifying a zeolite by reaction, under dry, anhydrous conditions, with an organosilane wherein the starting zeolite has some sites available for reacting with the organosilane and some protected sites which are prevented from reacting with said organosilane which remain to be the catalytically active sites. The organosilane chosen should be capable of entering into the channels of the zeolite and chemically reacting with the available sites present therein, as well as reacting with the available hydroxyl groups present on the external surface of said zeolite.
