METHOD OF REGENERATION OF ALUMINIUM-PLATINUM CATALYST OF REFORMING Russian patent published in 1995 - IPC

Abstract RU 2035220 C1

FIELD: processing of oil; regeneration of aluminium- platinum catalyst of reforming. SUBSTANCE: in the oxygen- containing gas medium coke is burned out at 200-500 C from the waste aluminium-platinum catalyst of reforming. Then the catalyst is treated by Freon in the circulating hydrogen- containing gas medium at 200-300 C, with consumption of Freon being 0.1-0.4 percent of fluorine mass. EFFECT: higher efficiency.
