摘要
将甲烷氯化物副产品偶联转化成多碳氯化物有很大的工业价值和良好的环境效应。本实验通过氯仿脱氯化氢偶联生成四氯乙烯,寻找合适的催化剂是本实验的重点。分别以活性炭和13X分子筛为载体,金属氯化物为活性组分,通过浸渍法合成实验所需催化剂。在固定床反应装置上,考察了一系列催化剂对氯仿脱氯化氢生成四氯乙烯反应的催化活性,本实验通过考察原料的转化率及产物的选择性来评价催化剂的性能,筛选出了相对高活性的FeCl_3-AC催化剂。反应温度为400℃,空速为1h~(-1)时,催化剂FeCl_3-AC的催化效果最佳,氯仿的转化率达94.1%,四氯乙烯的选择性为30.9%。
There are great industrial value and good environmental effects in converting by-products from methane chloride to the chloride containing more carbons.In this study,tetrachlorethylene generates by dehydrochlorination of chloroform couple,and it is the key to finding an appropriate catalyst.The catalysts were synthesized by dipping,while activated carbon and 13 X zeolite were chosen as the carriers respectively,and metal chloride was chosen as the active component.Under the condition of reaction temperature 400 ℃,weight hourly space velocity1h~(-1),the catalyst FeCl3-AC had best catalytic activity.The conversion of chloroform is 94.1%,the selectivity of tetrachloroethylene is 30.9%.
