阅读说明：本技术 对二甲苯生产的集成方法 (Integrated process for para-xylene production ) 是由 丁忠义 萨钦·乔什 W·金 于 2019-07-19 设计创作，主要内容包括：公开了对二甲苯生产方法,其中此类方法与提取蒸馏或其它分离集成以有效分离,例如去除和回收,乙苯和其它与二甲苯异构体共沸的组分。这使得能够在对二甲苯与其其它异构体分离的下游在更温和的条件(例如液相,不存在外加氢气)下进行二甲苯异构化,而不需要乙苯转化。相关的降低的副产物(如轻质气体和非芳族烃)的收率以及对苯乙烯单体生产有价值的提纯乙苯的生成可以显著改善整体方法经济性。(Disclosed are para-xylene production processes wherein such processes are integrated with extractive distillation or other separations to effectively separate, e.g., remove and recover, ethylbenzene and other components that are azeotropic with xylene isomers. This enables xylene isomerization to be carried out under milder conditions (e.g., liquid phase, in the absence of added hydrogen) downstream of the separation of paraxylene from its other isomers, without the need for ethylbenzene conversion. The associated reduced yields of by-products (e.g., light gases and non-aromatic hydrocarbons) and the production of valuable purified ethylbenzene from styrene monomer can significantly improve overall process economics.)
