CS-PT/GE-ZSM-5 HYDROCARBON AROMATIZATION CATALYST COMPOSITION AND METHOD OF FORMATION

摘要

A method for forming a catalyst can comprise: heating a Ge-ZSM-5 zeolite powder at a temperature of 400 to 600C; ion-exchanging the heat-treated zeolite powder with an alkali metal and impregnating the heat-treated zeolite powder with noble metal; heating the ion-exchanged, impregnated zeolite powder to a temperature of 250 to 350C; mixing the second heat-treated zeolite powder with a solid silica binder and a colloidal silica binder to form a mixture, wherein if the solid silica has a purity of less than or equal to 66 wt% of silica oxide based on the total weight of the solid silica, then the mixture is free of an extrusion aide and the colloidal silica has a particle size of less than 20 nm as measured along a major axis; forming the mixture into a shaped body; and heating the shaped body to result in the catalyst.
