英文摘要Pt@CeO2 and Pt@Ce0.67Zr0.33O2 prepared by microemulsion method were studied for water-gas shift reaction in pure syngas and sour syngas from 573 K to 773 K. Both showed high catalytic activities in pure syngas with CO conversion (X-CO) nearly to equilibrium status at temperature above 723 K. and the side reaction of methanation was inhibited throughout the temperature range. Pt@Ce0.67Zr0.33O2 showed lower X-CO in pure syngas, but higher in sour syngas than Pt@CeO2, indicating that the former is more resistant to H2S than the latter. Although a decrease in X-CO was observed in sour syngas relative to pure syngas, stability experiments carried out over Pt@Ce0.67Zr0.33O2 indicated that the catalytic activity could be recovered after the removal of H2S.
