| 摘 要： | 以合成气(CO/CO2/H2)为原料,Cu-Zn基为催化剂,2-丁醇为溶剂,低温低压(443 K,3.0 MPa)下合成甲醇.醇溶剂参与反应,但并不被消耗,起到了助催化作用.考察了载体、稀土助剂对催化剂活性的影响,结果表明ZnO,MgO,Al2O3,La2O3,Y2O3作为载体制得的催化剂中,Cu/ZnO在反应中呈现了最高的反应活性;稀土元素作为助剂,能提高Cu-Zn基催化剂的活性,Y的质量分数为7.5%的Cu/ZnO/Y2O3和La的质量分数为10%的Cu/ZnO/La2O3催化剂在反应中均呈现出最高的反应活性,碳的总转化率比使用Cu/ZnO催化剂分别提高了10%和17.5%,两者甲醇的产率...

| Abstract: | Methanol was synthesized with syngas(CO/CO2/H2) as starting material and Cu-Zn based catalysts at low temperature/pressure(443 K/3.0 MPa),where the 2-butanol was used as solvent.In such a reaction process the alcohol solvent was not consumed but played a catalytic role.The effects of the carriers and rare-earth additives on the activity of catalyst were investigated,and the results showed that the Cu/ZnO catalyst exhibits the highest activity in all catalysts prepared using ZnO,MgO,Al2O3,La2O3,Y2O3 as carri... |
