Abstract

A process for aromatic transalkylation and olefin reduction of a feed stream is disclosed. Transalkylation conditions produce xylenes and reduced olefins in the feed. The process 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.
