摘　　要：制备了活化炭化树脂载体,采用乙二胺为溶剂的Ni（NO3）2溶液等体积浸渍法制备了活化炭化树脂负载的Ni催化剂借助BET、SEM、XRD、TEM和微反应器等技术对活化炭化树脂及负载金属镍催化剂的表面结构和催化加氢脱氯性能进行了表征和评价实验结果表明：经过活化处理的炭化树脂的比表面积达611m2/g;用活化炭化树脂负载金属镍的平均粒径为30um,且分布均匀;在适宜的反应条件下,以质量分数为2％的Ni／活化炭化树脂作催化剂,1,2-二氯丙烷的转化率大于68％,生成丙烯的选择性为100％.The carbonized resin support has been prepared. The Ni catalysts have been prepared by isometric impregnation of Ni(NO3)2 solution with carbonized resin support using ethylenediamine as solvent. Their superficial structures have been characterized by BET, SEM, XRD and TEM techniques. The reaction behavior of Ni supported on the carbonized resin in hydrodechlorination of 1, 2-dichloropropane to propene have been evaluated in a microreactor. The results show that the carbonized resin after activation has a specific area of 611 m2/g, the nickel supported on the resin has an average crystal size of 30 um and distributes uniformly. Over the activated carbonized resin supported nickel catalyst for hydrodechlorination of 1, 2-dichloropropane the latter has conversion more than 68% with the selectivity to propene being 100% under proper reaction conditions.
