Abstract
A process for producing aromatic hydrocarbons which comprises (a) contacting ethane with a dehyroaromatization aromatic catalyst which is comprised of about 0.005 to about 0.1 wt % platinum, an amount of gallium which is equal to or greater than the amount of the platinum, from about 10 to about 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.
Claims19
A process for producing aromatic hydrocarbons which comprises:
- (a) contacting ethane with a dehydroaromatization catalyst which comprises:
- (1) 0.01 to 0.05 wt % platinum, based on the total weight of the catalyst calculated as metal,
- (2) an amount of gallium equal to or greater, by weight, than the amount of the platinum, basis the metal, and no more than about 1 wt %, based on the total weight of the catalyst calculated as metal;
- (3) about 10 to about 99.9 wt % of an aluminosilicate, and
- (4) a binder;
- (b) collecting the products from (a) and separating and recovering C6+ aromatic hydrocarbons,
- (c) optionally recovering methane and hydrogen;
- and
- (d) optionally recycling C2-5 hydrocarbons to (a).
