摘要:

采用浸渍法制备了Ni/AC催化剂，考察了后处理条件和反应条件对Ni/AC催化剂催化甘油氢解制备二元醇性能的影响，以及添加剂NaOH对反应的影响，采用H2TPR、XRD对催化剂进行了表征.研究结果表明:以Ni/AC为催化剂催化甘油氢解，若反应体系中不加NaOH时甘油的转化率很低，而加入NaOH可以大幅度提高甘油的转化率.Ni/AC催化剂在350℃氢气直接还原3 h后催化剂活性最好.

Abstract:

The Ni/AC catalyst was prepared by impregnation method. The catalyst was characterized by XRD,H2TPR and tested in the reaction of glycerol hydrogenolysis to diols. The effect of heat treatment conditions of Ni/AC catalyst, reaction conditions and the addition of NaOH on the performance of the catalyst in the reaction were investigated. The results show that Ni/AC reveals very low the conversion of glycerol in the absence of NaOH; whereas, the glycerin conversion was improved obviously with the addition of NaOH. The Ni/AC catalyst reduced directly by hydrogen at 350℃ show the best catalytic performance.
