摘要

采用共浸渍法对不同锆用量的Ni/Zr-HMS/HZSM-5催化剂进行了苯加氢反应。采用X射线衍射、X射线荧光、傅里叶变换红外光谱、紫外-可见漫反射光谱、程序升温解吸氨、H2化学吸附、N2吸附-解吸、热重分析等方法对制备的镍催化剂的理化性质进行了表征。在固定床反应器(反应温度130 ~ 190℃)上评价了催化性能。结果表明，Si/Zr = 35的镍催化剂表现出较好的催化性能和稳定性，在长期性能上具有较好的选择性。

Nickel Hydrogenation Composite Catalysts Modified by Zirconium in Competitive Benzene Hydrogenation: Effect of Modifiers

A co-impregnation method was applied to the Ni/Zr-HMS/HZSM-5 catalyst (with various amounts of zirconium) during the hydrogenation of benzene. The physicochemical properties of the prepared nickel catalyst were characterized using X - ray diffraction, X - ray fluorescence, Fourier transform infrared spectroscopy, ultraviolet-visible diffuse reflectance spectroscopy, temperature-programmed desorption of ammonia, H2 chemisorption, N2 adsorption - desorption, and thermogravimetric analysis. The catalytic performance was assessed on a fixed-bed reactor (reaction temperature between 130 °C and 190 °C). The results indicated that the nickel catalyst with Si/Zr = 35 exhibited better catalytic performance and stability than others, so providing a better selectivity in long-term performance.
