Patent ID: 7816573

Claim:
A process for converting hydrocarbons comprising the step of contacting a hydrocarbon feedstock under conversion conditions with a catalyst, said catalyst comprising a crystalline molecular sieve composition obtainable by a) crystallizing a pre-formed extrudate mixture in a reactor, the pre-formed extrudate 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 mole composition: Y:X 2 =10 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; and b) during crystallization, removing excess alkali metal hydroxide from the pre-formed extrudate.
