Abstract: A process for the production of benzene and ethylene from an alkane-containing gas stream. The alkane-containing gas stream may be contacted, in a reaction zone of a reactor under alkane aromatization conditions, with an aromatization catalyst including any combination of fresh, spent, and regenerated catalyst to produce an outlet stream including (i) spent catalyst and (ii) a product mixture including benzene and ethylene. The spent catalyst may be regenerated in a regeneration zone under regeneration conditions to produce the regenerated catalyst. A selected amount of fresh catalyst may be added to the regeneration zone to produce the mixture of fresh catalyst and regenerated catalyst, which may be recycled to the reaction zone. A ratio of benzene to ethylene in the product mixture may be controlled by modifying the alkane aromatization conditions, the regeneration conditions, and/or the selected amount of fresh catalyst added to the regeneration zone.
