摘要： A method for minimizing the loss of xylenes in an ethylbenzene conversion/isomerization process by adding toluene to the feedstock. The concentration of toluene in the feedstock is increased by co-feeding toluene or by recycling toluene separated from the ethylbenzene conversion reactor effluent. The increased toluene concentration reduces the loss of xylenes during the ethylbenzene conversion reaction and under preferred operating conditions increases the amount of xylenes in the product.

摘要： A method for increasing the efficiency of xylene isomerization by using a two stage isomerization process. In the first stage of the process, a C.sub.9.sup.+ aromatics feedstock is subjected to ethylbenzene conversion and xylene isomerization. Non-C.sub.8 aromatics are removed from the effluent, which is then processed in a second stage of the process to remove para-xylene and isomerize the para-xylene depleted effluent. The effluent from the second stage isomerization unit is then recycled into the inlet of the second stage of the process and a slip stream from the para-xylene separator is recycled to the feedstock and to the effluent of the ethylbenzene conversion unit. In this way, the production of para-xylene is maximized. In a preferred embodiment, toluene is co-fed into the feedstock to minimize the loss of xylenes during the ethylbenzene conversion reaction.
摘要翻译： 一种通过使用两级异构化方法提高二甲苯异构化效率的方法。 在该方法的第一阶段，C9 +芳烃原料进行乙苯转化和二甲苯异构化。 从流出物中除去非-C 8芳族化合物，然后在该方法的第二阶段中处理以除去对二甲苯并使对二甲苯贫乏的流出物异构化。 然后将来自第二级异构化单元的流出物再循环到该方法的第二阶段的入口中，并且来自对二甲苯分离器的滑流再循环至原料和乙苯转化单元的流出物。 以这种方式，对二甲苯的生产最大化。 在优选的实施方案中，将甲苯共同进料到原料中以使乙苯转化反应期间二甲苯的损失最小化。
