Preparation of Highly Dispersed Co/SiO<sub>2</sub> Catalyst Using Ethylene Glycol and Its Application in Vapor-Phase Hydrogenolysis of Ethyl Lactate to 1,2-Propanediol

Abstract: MPa、160°C 和 10% (w,质量分数) Co/SiO2)乳酸乙酯的转化率从 69.5%提高到 98.6%,1,2-丙二醇的选择 性达到 98.0%。利用 X 射线衍射(XRD)、透射电子显微镜(TEM)、X 射线光电子能谱(XPS)、N2吸脱附实验、 H2程序升温还原(H2-TPR)等表征手段对共浸渍制备的 Co/SiO2催化剂结构和形貌进行了表征分析。 关键词:Co/SiO2;共浸渍;乳酸乙酯加氢;1,2-丙二醇;乙二醇 中图分类号:O643
