Abstract
A thermochemical labyrinth reactor is disclosed. The reactor has a reoxidation zone and a reduction zone with electric heaters. A recuperation zone connects the reduction and reoxidation zones with first and second channels, the first channel adjoining the second channel, being separated by windows allowing an exchange of thermal radiation between channels while preventing gas exchange. The reactor also includes reactor plates composed of a reactive material, and a transit system running through the three zones, with the transit system configured to shuttle the plates between the reduction zone and the reoxidation zone, moving the plates along a circuit. The reactor also has a feedstock gas emitter to introduce a feedstock gas flowing opposite the movement of the plates. A gas extractor is configured to extract a product gas resulting from the feedstock gas being split by the oxidizing reactive material. All three zones are surrounded by an insulating housing.
