【摘要】 在固定床连续流动反应器装置上,考察不同氧化物改性 CuO/Zno/AL₂O₃催化剂对 CO₂加氢合成甲醇反应的催化性能。结果表明,Ag₂O、ZrO₂助剂的加入提高了 CuO/ZnO/Al₂O₃催化活性。Ag₂O、ZrO₂ 含量在2.3mol%时,反应的 CO₂转化率、甲醇选择性和产率最佳。更多还原

【Abstract】 The effects of various promoters on the modification of:CuO/ZnO/Al₂O₃ catalyst were studies for methanol synthesis from CO₂ hydrogenation in the assembling of a fixed-bed flow reactor. The results show that the addition of Ag₂O and ZrO₂ can increase the catalytic activity,the content of Ag₂O and ZrO₂ is 2-3mol%,the conversation of CO₂ and the selection and yield of methanol were optimal.更多还原
