摘　　要：采用草酸盐胶态共沉淀-机械混合法制备了Cu-Mn-La/γ-Al2O3催化剂,将该催化剂用于二甲醚重整制氢反应,考察了反应温度、装填方式、水醚比等工艺条件的影响。测试结果表明,较好的工艺条件是:反应温度350℃,水醚比3,较好的装填方式是将两种活性组分机械混合后装填。在优化的工艺条件下,Cu-Mn-La/γ-Al2O3催化剂具有较好的催化活性和稳定性。Cu-Mn-La/γ-Al2O3 catalysts were prepared by gel oxalate precipitation-mechanical mixing method.The effects of process conditions,including reaction temperature,catalyst loading types and steam/DME ratio,on hydrogen production by steam reforming of dimethyl ether over Cu-Mn-La/γ-Al2O3 catalysts were investigated.The results showed that the suitable process conditions were reaction temperature of 350℃,catalyst loading in a type of thorough mixture and steam/DME mole ratio of 3.0.Under the suitable process conditions,Cu-Mn-La/γ-Al2O3 catalyst showed better catalytic activity and stability.
