OFF-SITE REGENERATION OF REFORMING CATALYSTS

摘要

Regenerating a spent hydrocarbon conversion catalyst comprising a noble metal (Group VIII metal, gold or silver), a halogen and a porous support is effected in a single fluidized bed reactor and comprises burning off coke with an oxygen-containing gas at 300-680 deg. C for 0.5-10 hours and oxyhalogenating the catalyst with a halogen compound in a controlled moist air atmosphere at 300-650 deg. C.
