Patent ID: 8809608

Claim:
A process for producing aromatic hydrocarbons which comprises: (a) contacting one or more lower alkanes with a dehydroaromatization catalyst in a reactor for from about 0.1 seconds to about 1 minute, said catalyst comprising: (1) about 0.005 to about 0.1% 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 not more than about 0.2% wt of the catalyst, basis the metal, and wherein the amount of platinum is not more than about 0.02% wt more than the amount of the attenuating metal, based on the total weight of the catalyst, (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 C 2-5 hydrocarbons to (a).
