Catalytic reformer process
A catalytic reformer process for the production of hydrogen and a product of enhanced aromatic content comprises the utilization of a plurality of reactor stages wherein the heat in the effluent from the terminal adiabatic stage of a conventional adiabatic reactor train is utilized in an ascending temperature pattern reactor, termed an alkylcyclohexane converter, by means of simultaneous heat exchange, to provide the endothermic heat of reaction required for the dehydrogenation to aromatics of the original alkylcyclohexanes in the feed. An ascending temperature pattern reactor, termed an alkylcyclopentane converter, may optionally be employed wherein heat supplied from stack gases generated by the conventional fired heaters in an adiabatic reactor train can, additionally, be employed to supply heat to such converter. With this reformer process, byproduct is improved as to hydrogen yields, at the expense of methane, ethane, and propane, the hydrogen having improved purity, and gasoline, and its characteristics, for a given research octane clear quality for a given feedstock, is produced in a thermally more efficient manner.
