CO-CURRENT CATALYST FLOW WITH FEED FOR FRACTIONATED FEED RECOMBINED AND SENT TO HIGH TEMPERATURE REFORMING REACTORS

摘要

A process is presented for the increasing the yields of aromatics from reforming a hydrocarbon feedstream. The process includes splitting a naphtha feedstream into a light hydrocarbon stream, and a heavier stream having a relatively rich concentration of naphthenes. The heavy stream is reformed to convert the naphthenes to aromatics and the resulting product stream is further reformed with the light hydrocarbon stream to increase the aromatics yields. The catalyst is passed through the reactors in a sequential manner.
