Abstract

Provided is a process for producing aromatics including the steps of preparing a C8 hydrocarbon stream, feeding a naphtha stream and the C8 hydrocarbon stream to a reforming unit, and reforming the naphtha stream and the C8 hydrocarbon stream to yield aromatics. The process combines a co-feed containing C8 hydrocarbons, an alkali/alkaline earth metal-containing reforming catalyst, and a high temperature operating regime to achieve significant improvements in a reforming process for the production of xylenes and other aromatics.
