Process for the conversion of ethane to aromatic hydrocarbons

摘要

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 an attenuating metal which is no more than about 0.02% wt less than the amount of 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.

1. 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 C6+ aromatic hydrocarbons, (c) optionally recovering methane and hydrogen; and (d) optionally recycling C2-5 hydrocarbons to (a).
