PROSES UNTUK ISOMERISASI HIDROKARBON-HIDROKARBON ALKILAROMATIK

摘要

A process for isomerizating a feed containing alkylaromatic hydrocarbons, e.g., monocyclic alkylaromatic hydrocarbons and/or bicyclic alkylaromatic hydrocarbons. The process is carried out by contacting the feed under conversion conditions with a zeolite bound zeolite catalyst which comprises first crystals of an intermediate pore size first zeolite and a binder which comprises second crystals of a second zeolite. The process finds particular applications in isomerizing a feed containing ethylbenzene and less than equilibrium amounts of xylenes with ethylbenzene and can produce a product containing above equilibrium quantities of para-xylene and low aromatics ring loss and xylene loss.
