ABSTRACT:
This invention relates to a method for synthesizing an ultra-large pore crystalline material and the use of such crystalline material as a sorbent and in catalytic conversion of organic and inorganic compounds. The synthesis method includes hydrothermally treating the as-synthesized crystalline material in the presence or absence of a binder. In a preferred embodiment, the crystalline material contains organic directing agent and is composited in an alumina binder. The crystalline material exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams at 50 torr and 25.degree. C., a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 Angstrom Units and a hexagonal arrangement of uniformly sized pores with a maximum perpendicular cross section of at least about 13 Angstrom units.
