Waste feed material, such as Automotive Shredder Residue (ASR) feed material, that includes hydrocarbon materials and inorganic materials is processed using photolysis. A reactor includes a chamber that receives waste feed material including a majority of hydrocarbon material after the substantial removal of inorganic material including metals and minerals. A photonic illumination or photolysis module irradiates the feed material within the chamber of the reactor to decompose the hydrocarbon or hydrocarbon materials within the waste feed material into gases and/or carbonaceous solids. A mechanical movement unit moves the waste feed material within the chamber of the reactor to facilitate exposure of different portions of the feed material to irradiation within the chamber during system operation. A pre-treatment module substantially removes the contained metals and minerals in the waste material from the hydrocarbon material fed to the reactor.

A multiple stage synthesis gas generation system is disclosed including a high radiant heat flux reactor, a gasifier reactor control system, and a Steam Methane Reformer (SMR) reactor. The SMR reactor is in parallel and cooperates with the high radiant heat flux reactor to produce a high quality syngas mixture for MeOH synthesis. The resultant products from the two reactors may be used for the MeOH synthesis. The SMR provides hydrogen rich syngas to be mixed with the potentially carbon monoxide rich syngas from the high radiant heat flux reactor. The combination of syngas component streams from the two reactors can provide the required hydrogen to carbon monoxide ratio for methanol synthesis. The SMR reactor control system and a gasifier reactor control system interact to produce a high quality syngas mixture for the MeOH synthesis.

In various embodiments, the present invention provides a reaction chamber, including a catalyst, and a heating chamber configured to receive light. The heating chamber is positioned underneath at least a portion of the reaction chamber.
