摘要:
A process is provided for the production of xylenes from reformate by reactive distillation. The process is carried out by methylating the benzene/toluene present in the reformate in a reactive distillation zone and under reactive distillation conditions to produce a resulting product having a higher xylenes content than the reformate. Greater than equilibrium amounts of para-xylene can be produced by the process.
摘要(中):
提供了一种通过反应蒸馏从重整产生二甲苯的方法。 该方法通过在反应蒸馏区和反应蒸馏条件下甲苯化存在于重整产物中的苯/甲苯来生产具有比重整产物更高的二甲苯含量的所得产物。 通过该方法可以产生大于平衡量的对二甲苯。
