Synthesis of mesoporous aluminosilicate

摘要

There is provided a method for synthesizing a new synthetic composition of ultra-large pore crystalline material which can be used as a sorbent or catalyst component for conversion of organic and inorganic compounds. The crystalline material product of this method 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 DEG C. This material may have a hexagonal electron diffraction pattern that can be indexed with a d100 value greater than about 18 Angstrom Units and a hexagonal arrangement of uniformly sized pores with a maximum perpendicular cross section of a least about 13 Angstrom units. The reaction mixture for preparing this material contains silica-alumina hydrogel.
