Patent ID: 8398955

Claim:
A method of preparing a molecular sieve composition having at least one crystalline molecular sieve comprising the steps of: a. providing a reaction mixture comprising at least one source of ions of tetravalent element Y, at least one source of alkali metal hydroxide, water, optionally at least one seed crystal, and optionally at least one source of ions of trivalent element X, said reaction mixture having the following molar composition: Y:X 2 =2 to infinity OH − :Y=0.001 to 2 M + :Y=0.001 to 2 wherein M is an alkali metal and the amount of water is at least sufficient to permit extrusion of said reaction mixture, wherein said reaction mixture is substantially free of a crystalline molecular sieve (not including the optional seed crystals); b. extruding said reaction mixture to form a pre-formed extrudate; and c. crystallizing said pre-formed extrudate in a liquid medium comprising water under liquid phase conditions to form said molecular sieve composition having said crystalline molecular sieve.
