| 摘 要： | 以有机改性蛭石为载体,RuCl3·x H2O为活性组分前驱体,采用吸附-沉淀法制备催化剂Ru/有机改性蛭石(Ru/OV),将其用于乙酰丙酸甲酯(ML)催化加氢反应中。采用X射线衍射(XRD)、N2物理吸附-脱附、透射电镜(TEM)、X射线光电子能谱(XPS)对催化剂进行表征。结合单因素和正交实验考察了反应温度、反应压力、反应时间对乙酰丙酸甲酯加氢效果的影响,在最佳工艺条件下乙酰丙酸甲酯的转化率达84%,γ-戊内酯(GVL)选择性达100%。经重复使用20次后,ML的转化率仍然保持在80%以上,GVL的选择性为100%。

| Abstract: | Organic-pillared vermiculite supported Ru (Ru/OV) was prepared via adsorption-precipitation method, using RuCl3·xH2O as precursor and applied to catalytic hydrogenation of methyl levulinate (ML). The physicochemical properties of the catalysts were investigated by XRD, N2-adsorption-desorption, TEM and XPS. Effects of reaction temperature, pressure, reaction time on the catalytic performance were studied by orthogonal and single factor experiments. Under the optimum conditions, the conversion of ML and the selectivity of γ-valerolactone (GVL) were 84% and 100%, separately. After being recycled for 20 times, the conversion of ML was above 80% and the 100% selectivity of GVL could be obtained. |
