| 摘 要： | 羟基新戊醛（HPA）的加氢多采用贵金属和铜系催化剂，为了更好地降低催化剂生产成本和操作成本，分别对比了共沉淀法和浸渍法制备的镍/氧化铝催化剂，并以HPA为原料，在固定床装置上考察了系列催化剂加氢合成新戊二醇（NPG）的催化性能。采用X射线衍射（XRD）、氮气物理吸附（BET）、一氧化碳脉冲吸附等方法进行表征，结果表明，浸渍法制备的20%镍/氧化铝催化剂，比表面积较大，金属分散性好，且催化剂中的镍物种易被还原，其反应性能良好。在相对较温和的反应条件下，即反应温度为103 ℃、反应压力为3 MPa、液时空速为1 h-1、氢醛物质的量比为10时，HPA转化率为100%，NPG选择性为99.3%。在1 000 h的长周期评价过程中，该催化剂保持了较好的活性，具有更好的工业化前景。

| Abstract: | Noble metals and copper-based catalysts had been often used for the hydrogenation of hydroxypivaldehyde（HPA）.In order to better reduce the production cost and operation cost of catalysts，Ni/Al2O3 prepared by co-precipitation method and impregnation method were compared respectively，and the catalytic performance of a series of catalysts for the hydrogenation of HPA as raw materials to neopentyl glycol（NPG） was investigated in a fixed bed reactor.X-ray diffraction（XRD），N2 physical adsorption（BET） and CO pulse adsorption were used for characterization.The results showed that 20%Ni/Al2O3 catalyst prepared by impregnation method had a good catalytic performance，which had a large specific surface area，good metal dispersion and the nickel species in the catalyst could be easily reduced，which had good reaction performance.Under relatively mild reaction conditions that reaction temperature of 103 ℃，reaction pressure of 3 MPa，liquid hourly space velocity of 1 h-1 and the ratio of hydrogen to aldehyde of 10，the conversion of HPA was 100% and the selectivity of NPG was 99.3%.In the long-term evaluation process of 1 000 h，the catalyst maintained good activity and had better industrial prospect. |
