摘　　要：采用浸渍法制备以γ-Al2O3为载体、稀土元素为助剂的多金属Pt系催化剂PtLaCoFeNi/γ-Al2O3;基于固定床反应器研究了催化剂的还原条件、催化活性及抗析碳性;通过单因素实验和正交实验分别研究了温度、水碳比、液空速、氧碳比四因素对柴油部分氧化重整制氢工艺的影响,并确定了最适宜的工艺条件为:温度680℃、液空速0.12 h-1、氧碳比0.2、水碳比20,此时每摩尔柴油可产氢38.5摩尔。A multi-metal Pt containing catalyst supported on γ-alumina with rare-earth promoter, PtLaCoFeNi/γ-A12O3, was prepared by impregnation method, and its catalytic activity, reductive conditions and carbon deposition resistance in partial oxidation reforming of diesel to produce hydrogen were studied in a fixed bed reactor. The effects of H2O/C and O2/C ratios, temperature, and liquid space velocity on the reaction were investigated through single element and orthogonal tests. 38.5 moles hydrogen could be obtained from one mole diesel under the optimum reaction conditions： 680 ℃, H2O/C molar ratio of 20, O2/C molar ratio of 0.2, and liquid space velocity of 0.12 h^-1.
