采用离子掺杂价态补偿原理，在Ｃｕ－Ｚｎ－Ａｌ甲醇合成催化剂中添加适量氧化锆助剂研制Ｃｕ－Ｚｎ－Ａｌ－Ｚｒ催化剂的特性。实验结果表明，最佳反应温度为２３０℃，比Ｃｕ－Ｚｎ－Ａｌ约低１０℃。采用ＸＲＤ、ＵＶＤＲ、ＦＴＩＲ、ＴＰＤ和ＴＰＲ等谱学方法对２种催化剂进行表征显示，铜基催化剂的活性位可能是“Ｃｕ０－Ｃｕ＋－Ｏ－Ｚｎ２／Ａ２Ｏ３－ＺｒＯ２”，工作态Ｃｕ－Ｚｎ－Ａｌ－Ｚｒ催化剂表面上Ｃｕ／Ｃｕ０的比值、价态稳定性和对ＣＯ的吸附量均大于Ｃｕ－Ｚｎ－Ａｌ，这与该催化剂具有较好的低温活性和较高的热稳定性密切相关。
The characteristics of Cu-Zn-Al-Zr catalysts for Cu-Zn-Al methanol synthesis by adding appropriate amount of zirconia additives were studied by using the principle of ion doping valence compensation. The experimental results show that the optimum reaction temperature is 230 ℃, about 10 ℃ lower than Cu-Zn-Al. Characterization of the two catalysts by XRD, UVDR, FTIR, TPD and TPR spectroscopy showed that the Cu-Cu-O-Zn2 / The Cu / Cu0 ratio, valence stability and CO adsorption on the Al-Zr catalyst surface are all greater than that of Cu-Zn-Al, which is closely related to the catalyst’s good low-temperature activity and high thermal stability.
