Abstract
This invention relates to a new synthetic composition of ultra-large pore crystalline material, a method for its preparation and use thereof as sorbent and in catalytic conversion of organic compounds. The new crystalline material exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams anhydrous crystal at 50 torr and 25.degree. C.
