摘要
Abstract
The ionic liquid [BMIM]HSO4 was synthesized by two steps and the Al2O3-supported [BMIM]HSO4 catalyst [BMIM] HSO4/Al2O3 was prepared by impregnation method. The catalyst was characterized by IR, TG-DTG and NMR, and its performances of catalytic dehydration of glycerol to acrolein were investigated in a fixed-bed flow reactor with the emphasis on the effects of reaction conditions including ionic liquid loading amount of catalyst, temperature and space velocity on the reaction and the stability of catalyst. The results showed that the optimum reaction conditions were as follows: ionic liquid mass, fraction in catalyst of 40%, temperature of 300℃ and liquid hourly space velocity of 6 h-1. Under the optimum conditions, the acrolein molar selectivity and glycerol conversion were 90.22% and 100%, respectively, and after 100 hours on stream, the yield of acrolein still reached 75%.关键词
