摘要
采用真空冷冻干燥法制备了一系列CuO-ZnO-ZrO2甲醇合成催化剂,在微型固定床反应器上考察了其对CO2加氢合成甲醇的催化性能及影响,并用XRD、H2-TPR、CO2-TPD、TEM、EDAX、BET等手段进行了表征。研究结果表明,采用真空冷冻干燥法能够制备出高比表面积、高活性、高选择性的甲醇合成催化剂CuO-ZnO-ZrO2。
A series of catalysts for methanol synthesis were prepared by vacuum freeze drying. Catalytic properties of catalysts were investigated with XRD, H2-TPR, CO2-TPD, TEM, EDAX, and BET and evaluation of catalytic activity was conducted in a micro fixed-bed reactor. The results showed that the catalysts for methanol synthesis prepared by vacuum freeze drying had high specific surface area, high activity and high selectivity.
