制备条件对非负载Ni-Mo复合氧化物催化剂加氢脱氧性能的影响OA北大核心CSCDCSTPCD
Effects of Preparation Conditions on the Properties of Unsupported Ni-Mo Composite Oxide Catalysts for Hydrodeoxygenation
以柠檬酸为络合剂,采用溶胶-凝胶法制备了非负载Ni-Mo复合氧化物催化剂,用N2吸附-脱附、XRD、SEM等手段对催化剂进行了表征.在连续流动固定床反应器上,以乙酸为探针分子考察了不同溶液pH值和溶剂量制备催化剂对催化加氢脱氧性能的影响.结果表明:溶胶-凝胶法制备的催化剂具有较高的比表面积和双介孔结构:主要以复合氧化物NiMoO4的形式存在;改变溶液的pH值和溶剂量,对催化剂的比表面积有一定影响.在初始溶液pH=1、溶剂量855 mL-(mol(…查看全部>>
Unsupported Ni-Mo composite oxide catalysts were successfully prepared by the sol-gel method with citric acid as the complex agent, and the prepared catalysts were characterized by using N2 adsorption-desorption, X-ray diffraction (XRD), and SEM In a continuous flow fixed-bed reactor, the effects of pH value and solvent volume used during preparation on the hydrodeoxygenation activity of the prepared catalysts were investigated emphatically by using acetic a…查看全部>>
