Its use in the isomerization catalyst and the aromatic C8 cut of aluminosilicate type containing at least one noble metal

摘要

PURPOSE: To enhance isomerization activity of arom. C8 hydrocarbon by depositing Pt, Pd on zeolite of a specific compsn. having alumina, silica, magnesia and clay, thereby forming a catalyst. CONSTITUTION: Zeolite of 12 to 1000 in a molar ratio SiO2 /Al2 O3 is synthesized by incorporating fluorine of 0.02 to 1.5 wt.% into a fluoride medium. The catalyst of an alumino silicate type is formed by depositing 0.01 to 1.5 wt.% at least one metal among platinum and palladium and 0 to 99.49 wt.% alumina, silica, magnesia, clay and at least two matrices thereof on 0.5 to 99.99 wt.% this zeolite. The platinum content in the catalyst is adequately 0.03 to 0.4 wt.%, the matrix content 10 to 60 wt.% and the zeolite content 40 to 90 wt.%, respective.
