## Abstract

A process for producing aromatic hydrocarbons which comprises (a) contacting ethane with a dehydroaromatization aromatic catalyst which is comprised of 0.005 to 0.1% wt platinum, an amount of iron which is equal to or greater than the amount of the platinum, from 10 to 99.9% wt of an aluminosilicate, and a binder, and (b) separating methane, hydrogen, and C2-5 hydrocarbons from the reaction products of step (a) to produce aromatic reaction products including benzene.

## Claims
