MoO3/SiO2催化甘油脱水氢转移还原制备烯丙醇
Glycerol Dehydration and Consecutive Hydrogen Transfer to Allyl Alcohol over MoO3/SiO2 Catalyst
摘要
Abstract
A series of MoO3/SiO2 catalysts was prepared by impregnation and was employed to produce allyl alcohol from glycerol. The catalysts were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), N2 Brunauer-Emmett-Teller(N2-BET), NH3 temperature programmed desorption( NH3-TPD) and Fourier transform infrared spectroscopy(FTIR) of pyridine adsorption. From glycerol to allyl alcohol, the effects of catalyst loading, reaction temperature, glycerol concentration, and gas hourly space velocity (GHSV) on the catalytic performance of Mo03/SiO2 were investigated in a fix-bed reactor. Under the optimal reaction conditions of 1 % ( mass fraction) loading, reaction temperature of 330℃ , atmospheric pressure, 40% (mass fraction) of glycerol concentration and GHSV of 200 h-1, glycerol conversion, selectivity for allyl alcohol and the space time yield of allyl alcohol can be as high as 92. 1% , 34. 8% and 6. 0 mmol·g-1·h-1, respectively.关键词
