The Technological Advances of Toluene Disproportionation and Transalkylation Process 甲苯歧化与烷基转移技术进展
In view of the fact that selective disproportionation process, though high in p-xylene concentration in the product, is not able to convert C 9A, a new process is proposed combining toluene selective disproportionation process with traditional toluene disproportionation process in the aromatic complex unit. 针对甲苯选择性歧化工艺能生产含高浓度对二甲苯的混合二甲苯、但不能处理C9A的特点,提出在芳烃联合装置中将甲苯选择性歧化和传统歧化组合在一起的组合工艺。
