Abstract

ChemInform Abstract From TPR studies it can be concluded that sulfur in sulfuric acid modified alumina samples, used as model systems for sulfided and regenerated Al2O3 supported catalysts, is reduced by H2 to the sulfide state at 500-750 rc C. Most of the sulfide is desorbed as H2S but a smaller part remains adsorbed on the alumina surface.
