XYLENE PRODUCTION PROCESSES AND APPARATUS WITH INTEGRATED FEEDSTOCK TREATMENT

摘要

A process and apparatus for aromatic transalkylation and olefin reduction of a feed stream is disclosed. Transalkylation conditions provide a product having increased xylene concentration and reduced olefin concentration relative to the feed. The process and apparatus may be used in a xylene production facility to minimize or avoid the necessity of feedstock pretreatment such as hydrotreating, hydrogenation, or treating with clay and/or molecular sieves.
