Simulated moving bed alkylation process

摘要

A continuous catalytic alkylation reaction and catalyst reactivation process is carried out using a simulated moving catalyst bed to effect simultaneously in different zones of a multi-zone, fixed catalyst bed, an alkylation reaction and a reactivation of catalyst. The catalyst of the present invention is a crystalline aluminosilicate zeolite composited with a Group VIII metal hydrogenation agent, and the reactivation medium utilized includes alkylatable hydrocarbon and hydrogen.
