Ru/TiO2催化剂上甘油氢解制1,2-丙二醇
DOI: 10.3724/SP.J.1088.2011.10534, PP. 1545-1549
Keywords: 钌,二氧化钛,甘油,氢解,1,2-丙二醇
Abstract:
？采用浸渍法制备了负载型Ru/TiO2催化剂,利用X射线衍射、X射线光电子能谱、高分辨透射电镜、N2吸附和电感耦合等离子体原子发射光谱等方法对催化剂进行了表征,并考察了反应温度、H2压力、甘油溶液浓度、催化剂用量和碱性添加物等因素对Ru/TiO2上甘油氢解反应性能的影响.结果表明,在170oC和3MPa的温和反应条件下,以LiOH为添加物,甘油转化率和1,2-丙二醇选择性分别高达89.6%和86.8%.
