| 摘 要： | 采用共沉淀法制备了一系列铜基催化剂,在N2中于高压釜中,考察了其催化甘油脱水制备羟基丙酮的反应性能.结果表明,Cu/SiO2催化剂具有较高的催化甘油脱水活性,但目的产物羟基丙酮易与反应产生的H2生成1,2-丙二醇,使得羟基丙酮选择性不高.因此,在固定床反应器上详细考察了在优选的Cu/SiO2催化剂上反应气氛、温度和空速...

| Abstract: | A series of Cu-based catalysts were prepared by the co-precipitation method,and their catalytic properties for the dehydration of glycerol to acetol were tested under N2 atmosphere in a stainless steel autoclave. The results showed that the Cu/SiO2 catalyst had higher catalytic activity than other catalysts. However,acetol can easily react with hydrogen that originated from the reaction process to 1,2-propanediol,leading to the low selectivity for acetol. Therefore,a fixed-bed reactor was selected to furthe... |
