丙二酸二乙酯在Cu/SiO2催化剂上的加氢过程OA北大核心CSCDCSTPCD
The hydrogenation process of diethyl malonate over Cu/SiO2 catalyst
在连续流动固定床反应器上，研究了Cu/SiO2催化丙二酸二乙酯（DEM）加氢制备1，3-丙二醇（1，3-PDO）的反应。采用H2-TPR、XRD、SEM、N2吸附-脱附等方法对催化剂进行表征。进一步优化了原料液含量、氢酯摩尔比、液态空速、反应温度、反应压力等因素对反应结果的影响。表征结果显示，不同还原条件会影响Cu/SiO2还原后活性铜的量及其分散状态；于300℃下还原4 h时，Cu/SiO2催化剂的活性中心较多且分散均匀。实验结果表明，采用于3…查看全部>>
The gas-phase hydrogenation of diethyl malonate to 1,3-propanediol over Cu/SiO2 catalysts was investigated in a continuous fi xed-bed reactor. The catalysts were characterized by means of H2-TPR,XRD,SEM and N2adsorption-desorption,which indicated that the active sites and their dispersity were aff ected by reduction conditions. The catalyst reduced at 300℃ for 4 h,which possessed more active sites and better dispersion,showed the optimum catalytic performanc…查看全部>>
