摘　　要：采用沉积沉淀法制备了Cu-Ni/γ-Al2O3催化剂,在连续流动的固定床反应器内,进行了二甲醚水蒸气重整制氢反应的研究,考察了还原温度、反应温度、系统压力、气体空速以及催化剂的粒径大小等工艺条件对Cu-Ni/γ-Al2O3催化剂上二甲醚水蒸气重整制氢反应性能的影响。实验结果表明,较优的工艺条件为:催化剂还原温度为400℃,粒径为0.45～0.90mm,反应温度为350℃,常压,气体进料空速为3240mL.(gcat.h)-1。Cu·Ni/γ-Al2O3 catalysts were prepared by deposition-precipitation method. Hydrogen production from dimethyl ether steam reforming was investigated in a fixed-bed continuous-flow stainless steel reactor. Process conditions of reduction temperature, reaction temperature, system pressure, space speed, and particle diameter were investigated on hydrogen production from dimethyl ether steam reforming over Cu·Ni/γ-Al2O3 catalysts. The results showed that the suitable process conditions are reduction temperature of 400℃, particle diameter of 0. 45-0. 90mm, reaction temperature of 350℃, under atmospheric pressure, and a space speed of 3240mL·（gcm·h）^-1.
