摘　　要：采用共沉淀法制备了LaNiO_3钙钛矿型复合氧化物催化剂,并用X射线衍射(XRD)、扫描电子显微镜(SEM)、程序升温还原(TPR)等对钙钛矿复合氧化物的晶相结构、微观形貌、还原性能等进行了表征。以蔗渣高压液化为探针反应,考察了LaNiO_3复合氧化物的催化活性和液化产物的分布规律,同时对液化反应时间、液化温度、催化剂用量、溶剂与蔗渣质量比等工艺条件进行了探讨。结果表明,最佳液化条件为:液质比15∶1、反应温度350℃、催化剂用量1.0 g、反应时间30 min。LaNiO_3 perovskite-type oxide catalyst was synthesised by coprecipitation method,the crystalline structure,shape and reducing properties of derived perovskite-type composite oxides were characterized by XRD、SEM、TPR.The catalyst activity and liquefaction product distribution of LaNiO_3 perovskite composite oxide were studied in bagasse high-pressure liquefaction.At the same time,the liquefied reaction time,liquefied reaction temperature,amount of the catalyst,liquid mass ratio and other process conditions are discussed.The results show that the best conditions are as following：liquefaction and liquid mass ratio 15∶1;liquefied reaction temperature 350 ℃;the amount of catalyst 1.0 g;liquefied reaction time 30 min.
