Abstract: A system and process to produce an aromatic hydrocarbon via catalyzed nonoxidative dehydroaromatization (DHA). The system includes a reaction zone containing a dehydroaromatization catalyst. A reactant feed stream inlet supplies a reactant composition, such as natural gas, to the reaction zone. A heater maintains the reaction zone at a suitable dehydroaromatization temperature. A product stream exit removes the aromatic hydrocarbon produced by the nonoxidative dehydroaromatization of the reactant composition from the reaction zone. A hydrogen separation membrane is disposed between the reaction zone and a hydrogen stream exit to enable continuous and selective removal of hydrogen produced in the reaction zone. A hydrogen recycle stream diverts a portion of hydrogen from the hydrogen stream exit and adds the portion of hydrogen to the reactant composition supplied to the reaction zone. The hydrogen may also be used to regenerate the dehydroaromatization catalyst.
