摘　　要：逆水煤气变换反应可以使CO2生成更有价值的CO,被认为是目前最有应用前景的CO2转化反应之一。本文采用浸渍法制备不同镍含量的Ni/HAp催化剂,通过XRD、TPR对催化剂进行了表征,并测试了其逆水煤气变换反应性能。结果表明,1%Ni/HAp催化剂中NiO颗粒较小,NiO与载体具有较强的相互作用,具有较高的逆水煤气变换反应活性和选择性;高含量的Ni/HAp中含有大颗粒NiO,NiO与载体相互作用较弱,反应中容易生成甲烷,降低了逆水煤气变换反应的选择性。Reverse water-gas shift reaction can convert CO2 to more valuable CO, which is considered to be one of the most promising reactions at present. In this paper, Ni/HAp catalysts with different Ni contents were prepared by impregnation method, and characterized by XRD and TPR. The catalytic performances of Ni/ HAp catalysts were tested in reverse water-gas shift reaction. The results showed that 1%Ni/ HAp catalyst has small NiO particle strong interacted with HAp, and exhibited good activity and selectivity for reverse water-gas shift reaction. The Ni/ HAp catalysts with higher Ni contents resulted in large NiO particles weakly interacted with HAp, and produced more CH 4 which decreased the selectivity of water-gas shift reaction.
