摘要
对从190#混合C9芳烃溶剂油中提纯连三甲苯的新工艺:烷基化—减压精馏—脱烷基—减压精馏的方法进行了研究。即首先通过分步实验法对新工艺的可行性进行了论证,得出可行的依据及较佳的工艺参数,其次对脱烷基的催化剂进行了制备,并通过连续实验对催化剂的寿命及活性进行了实验验证,从而得出性能较好的催化剂。
A new purification process of hemellitene（1,2,3-trimethylbenzene） from 190# C9 mixed aromatics solvent oil,alkylation-vacuum distillation-dealkylation-vacuum distillation process was studied.Firstly,feasibility of the new process was discussed through step-experiments,and better process parameters were obtained.Secondly,dealkylation catalysts were prepared,and catalyst life and activity were tested through continuous experiment.Futhermore,the better catalyst was selected.
