HIGH ALUMINUM CONTENT ALUMINOSILICATE MOLECULAR SIEVES AND THEIR MANUFACTURE |
摘要 |
A process for manufacturing a synthetic porous crystalline molecular sieve requires an aqueous reaction mixture comprising a source of X2O3 (X is a trivalent element), a source of YO2 (Y is a tetravalent element) and a source of MOH (M is an alkali metal). The H2O/MOH molar ratio is within the range of 70 to 126 and the source of X2O3 and YO2 is an amorphous material containing both X2O3 and YO2 and having YO2/X2O3 molar ratio of 15 or less. The molecular sieve products are useful as catalysts and/or absorbents. Such molecular sieves having MFI structure type, TON structure type or the structure type of zeolite beta and a composition involving the molar relationship (n) YO2:X2O3 wherein n is from 2 to less than 15 are novel compositions of matter. |
