US 2002/0001564 A1 · Aluminosilicate compositions, preparation and use

Abstract

A method for preparing a metalloaluminosilicate, includes the steps of: providing a solution containing a silica source; providing a solution containing an alumina source; providing an aqueous acid solution containing a metal other than silicon or aluminum; mixing the silica source solution with the aqueous acid solution so as to form a silica source-metal containing mixture; mixing the silica source-metal containing mixture with the alumina source solution so as to provide a gel mixture; and hydrothermally crystallizing the gel mixture so as to provide a metalloaluminosilicate material having an aluminosilicate framework and having the metal incorporated into the aluminosilicate framework. A method for preparing aluminosilicate, and specific compositions, are also provided.
