摘　　要：用湿混法制备用于甲醇组合重整制氢CuZnAlZr催化剂,与目前最常用的共沉淀法相比较,虽然湿混法催化剂的低温活性低于共沉淀法催化剂,但其在中高温段的催化活性与共沉淀法相当,且具有更高的CO_2选择性。XRD、TPR等表征结果显示,湿混法催化剂中有铜铝复合氧化物存在,铜组分的分散度很高。A CuZnAlZr-oxide catalyst for combined methanol reforming was prepared by a simple wet-mix method. Contrasted to the catalyst prepared by traditional co-precipitation method, the wet-mixed catalyst shows similar activity above 250℃ and lower activity below 250℃, also shows the higher selectivity to CO_2. The physicochemical properties of the catalysts were investigated by X-ray diffraction (XRD), temperature-programmed reduction (TPR), and surface area measurements. The catalyst characterization suggests th...
