Periodische Regenerierung von festen Alkylierungskatalysator mit Wasserstoff

摘要

Deactivated solid catalytic composites of the reaction product of a metal halide having Friedel-Crafts activity with the bound surface hydroxyl group of inorganic oxides and containing a zerovalent metal with hydrogenation activity, used as a catalyst in motor fuel until deactivated, is regenerated by treating the composite after alkylate feedstock has been removed with hydrogen at regeneration conditions including a temperature in the range of 10 to 300 DEG C. Multiple regenerations are possible without appreciable activity loss.
