PROCESS FOR REGENERATING A SOLID REACTANT

摘要

PROCESS FOR REGENERATING A SOLID REACTANT A process is disclosed for regenerating a solid reactant comprising a metal or metal compound disposed on a porous support which has been expended by reaction with hydrogen sulfide comprising the steps: (1) contacting the expended solid reactant with dilute oxygen in an inert diluent gas at a temperature in the range of from 200 to 425.degree.F., (2) contacting the solid material from step (1) with a reducing gas at a temperature in the range of 300 to 500.degree.F., and (3) heating the solid material resulting from (2) to a temperature in the range of from 450 to 600.degree.F. in an inert atmosphere.
