FEEDSTOCK GAS REACTOR WITH REGENERATIVE HEAT EXCHANGER

A feedstock gas reactor includes a reaction chamber and a first regenerative heat exchanger. A feedstock gas is flowed into the reaction chamber via the first regenerative heat exchanger. The feedstock gas is decomposed in the reaction chamber so as to produce reaction products. The reaction products are flowed out of the reaction chamber. The feedstock gas reactor may also include a second regenerative heat exchanger, and the reaction products may be flowed out of the reaction chamber via the second regenerative heat exchanger. Heat from the reaction products may stored in the second regenerative heat exchanger as the reaction products flow through the second regenerative heat exchanger, for later transfer to a feedstock gas flowing into the reaction chamber via the second regenerative heat exchanger.
