摘要
采用溶胶-凝胶法和浸渍法制备Cu/Zn/TiO2负载型催化剂,研究了不同Cu、Zn负载量对催化剂性能的影响,采用BET、XRD、TPR对催化剂进行了表征.考察了反应温度、压力和催化剂组成对CO2加H2催化合成甲醇的影响.
The supported catalyst Cu/Zn/TiO2 was prepared by sol-gel and impregnation method, and the effects of Cu and Zn loading on the catalytic activity were studied. The catalyst was characterized with BET, XRD, TPR. Effects of temperature, pressure and composition on the carbon dioxide hydrogenation to synthesise methanol were studied.
