摘　　要：实验研究了以浸渍法制备的负载型Ru/γ-Al2O3催化剂体系上甲烷与氘化氢之间的氢氘交换性能,考察了各反应工艺条件包括反应温度、反应原料气流量、反应原料气中HD/CH4的比等因素对Ru/γ-Al2O3催化剂上甲烷与氘化氢之间的氢氘交换性能的影响,采用程序升温还原(H2-TPR)和X射线粉末衍射(XRD)手段对催化剂进行了检测。实验结果表明,Ru和载体γ-Al2O3发生了强相互作用;在对甲烷与氘化氢间的氢氘交换反应中,Ru/γ-Al2O3催化剂显示出较好的催化活性和稳定性。The Ru/γ-Al2O3 catalyst was prepared via incipient impregnation method, and the catalytic properties in the hydrogen-deuterium exchange of methane have been examined over γ-Al2O3 supported Ru catalyst. The effects of various parameters, such as the temperature of reaction, the flow of reactant, the ratio of HD/CH4, on structure and performance were investigated and catalysts were measured through the H2-TPR, XRD. The results indicate that the Ru atoms are in the support interior of the Ru/γ-Al2O3 catalyst and the stronger interaction between Ru and support on the Ru/γ-Al2O3 catalyst. The Ru/γ-Al2O3 catalyst possesses higher catalytic activity and stability in the hydrogen-deuterium exchange of methane.
