摘要
The stability and the activity of Fe2O3/Cr2O3 and ZnO/Cr2O3 catalysts were examined for a reverse-water-gas-shift reaction (RWReaction). The initial activities of those catalysts were quite high so that the conversion reached close to equilibrium. The activity of Fe2O3/Cr2O3 catalyst decreased from 33.5 to 29.8% during the RWReaction for 75 h at 873 K with GHSV (ml/g(cat) . h) of 100,000. Moreover, the coke formation on the Fe2O3/Cr2O3 catalyst caused clogging in the RWReactor of the CAMERE process. On the other hand, the ZnO/Cr2O3 catalyst showed no coke formation and no deactivation for the RWReaction at 873 K with GHSV (ml/g(cat) . h) of 150,000. The ZnO/Cr2O3 was a good catalyst for the RWReaction of the CAMERE process.
