摘要
通过正交试验初步确定催化剂的制备工艺,结合单因素实验对催化剂的组成进行了深入考察。在H2O/CH3OH摩尔比为1.3、液空速为1.5 h-1、反应温度为220℃和250℃的条件下,考察了铬助剂对催化剂性能的影响。结果表明,Cu/Cr质量比为1∶1时催化效果最佳,出口气体中CO的含量降低了50%,甲醇的转化率提高了20%。
Catalyst composing was investigated by orthogonal test in combination with single factor experiment. The effects of Cr-promoter and different mass ratios on the catalyst performance were investigated at 220℃and 250℃. The mole ratio of steam to methanol was 1.3, and the liquid space velocity was 1. 5 h^-1. The result is：the best Cu/Cr mass ratio was 1 ： 1 ,and the CO content decreased 50% while the methanol conversion increased 20% by using this catalyst.
