Patent ID: 8871990

Claim:
A process for producing aromatic hydrocarbons which comprises: (a) contacting ethane with a dehydroaromatization catalyst in a reactor for from about 0.1 seconds to about 1 minute, said catalyst comprising: (1) 0.005 to 0.05% wt platinum, based on the total weight of the catalyst, calculated as metal, (2) an amount of an attenuating metal selected from the group consisting of tin, lead, and germanium, which is no more than about 0.02% wt less than the amount of platinum, 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 C 6+ aromatic hydrocarbons, (c) optionally recovering methane and hydrogen; and (d) optionally recycling C 2-5 hydrocarbons to (a).
