process for preparing an mfi type metalloaluminosilicate without the use of organic templates or sowing procedures, and mfi type metalloaluminosilicate composition.
process for preparing an mfi type metalloaluminosilicate without the use of organic templates or sowing procedures, and mfi type metalloaluminosilicate composition.
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.
