CRYSTALLINE POROUS SILICATE COMPOSITE AND ITS USE IN CATALYTIC CRACKING

摘要

Catalyst compositions of inorganic oxide-bound shape-selective porous crystalline silicates are prepared by adding binder precursors to a porous crystalline silicate reaction mixture which contains unincorporated silica, in situ formed porous crystalline silicate and water. The resulting compositions exhibit improved hydrothermal stability and octane enhancement as additives in catalytic cracking.
