Abstract:
A process for the manufacture of large crystal size synthetic porous crystalline molecular sieve requires an aqueous reaction mixture that is organic structure directing agent-free, has a H2O/MOH molar ratio (M is an alkali metal) of 75 or less, a source of X2O3 (X is a trivalent element) and a source of YO2 (Y is a tetravalent element). The source of X2O3 and YO2 is an amorphous material containing both X2O3 and YO2 and having a YO2/X2O3 molar ratio of 15 to 40. The resultant highly crystalline novel materials have crystals with at least one dimension greater than 1 μm, such as greater than 3 μm.
