【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。
[Abstract]:LaNiO _ 3 perovskite-type composite oxide catalyst was prepared by co-precipitation method, and the crystal phase structure, micro-morphology and reducing property of the perovskite composite oxide were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and program temperature-raising reduction (TPR). The catalytic activity and distribution of the liquefied product of the LaNiO _ 3 composite oxide were investigated by the high-pressure liquefaction of bagasse as the probe, and the process conditions such as the liquefaction reaction time, the liquefaction temperature, the catalyst dosage, the solvent and the bagasse mass ratio were discussed. The results show that the optimum liquefaction condition is that the liquid mass ratio is 15:1, the reaction temperature is 350 鈩，
