PROCESO PARA REGENERACION DE CATALIZADORES

A process for regenerating, and reactivating, coked noble metal catalysts, especially platinum-containing polymetallic catalysts. A gas is employed for burning coke from the coked catalyst comprising an admixture of from about 0.1 percent to about 10 percent oxygen, and at least about 20 percent car...

More Information
Summary:A process for regenerating, and reactivating, coked noble metal catalysts, especially platinum-containing polymetallic catalysts. A gas is employed for burning coke from the coked catalyst comprising an admixture of from about 0.1 percent to about 10 percent oxygen, and at least about 20 percent carbon dioxide. The higher heat capacity of the carbon dioxide permits the use of a higher oxygen content regeneration gas, particularly during the primary coke bum, as contrasted with the regeneration gas used in conventional catalyst regeneration processes which contain large amounts of nitrogen and flue gas as inert gas.
