| Abstract: | Solid State Reactions in Catalysts and Components of Catalysts. XV. On the Reduction Behaviour of Sulfate Ions in γ-Al2O3 Different sulphuric acid modified alumina samples were used as model systems for sulfided and regenerated Al2O3 carrier catalysts. From investigations of temperature programmed reduction can be concluded that sulphur is reduced by hydrogen to sulfide state at temperatures between 500 and 750°C. The greater part will desorbed as H2S but a smaller one remains adsorbed on the alumina surface. |
