Novel Three-component Zeolite Capsule Catalyst for Direct Synthesis of Isoparaffin

Abstract

One zeolite capsule catalyst with core(Co/Al₂O₃)/shell(H-beta membrane) structure was prepared and used for isoparaffin direct synthesis via FTS reaction. Based on this core/shell zeolite capsule catalyst, a novel palladium painted zeolite capsule catalyst with three-component core (Co/Al₂O₃)/shell (H-beta membrane)/paint (Pd) structure was designed. In the isoparaffin synthesis on this three-component zeolite capsule catalyst, the olefins effused from the zeolite capsule catalyst were in-situ hydrogenated effectively, mostly converted to isoparaffin.
