Abstract

Solid reaction components contg. a metal cpd. on a porous carrier, and exhausted by reaction with H2S, are regenerated by (1) heating the spent solid material with dilute oxygen in an inert gas stream at 90-220 degrees C, (2) contacting the material from stage (1) with a reducing gas at 150-260 degrees C and (3) heating the product from stage (3) in an inert atmosphere at 200-320 degrees C. Method is esp. for regenerating solid reaction agents caused for removing H2S from recycle H2 streams used in reforming processes. Typical solid reaction materials have a carrier e.g. of active carbon, silica or clay and the metal cpd. is a mixture of Cu- and Cr oxides or a mixt. of Ni- and Mo oxides.
