A Study of Mox Modified α-NiO/γ-Al2O3 Catalyst for Water-gas Shift Integrated with Methanation

摘要：

Water-gas shift integrated with methanation was carried out over metal oxide modified α-NiO/γ-Al2O3 catalyst in a continuous flow type fixed-bed reactor.The effects of preparation method,reaction condition,and promoter type were all investigated.The experimental results showed that Co3O4 modified α-NiO/γ-Al2O3 catalyst prepared by grind-mixing method exhibited better activity than NiO-CuO/γ-Al2O3 and NiO-Fe2O3/γ-Al2O3 under reaction condition of the molar ratio of CO/H2/H2O=3:1:1,593 K and atmospheric pressure.The CO conversion of NiO-Co3O4(10 w％)/γ-Al2O3 catalyst was 7.8％ and the CH4 selectivity reached 83.2％.The NiO-MOx/γ-Al2O3 catalysts were analyzed by X-ray diffraction,temperature programmed reduction and thermogravimetry
