A system for producing a syngas from a biomass material. The system compacts a loose biomass material to form a compacted biomass material at an entrance of a reactor tube, and then heats the compacted biomass material within the tube to form ash and a fuel gas mixture. The fuel gas mixture is withdrawn from the tube and the ash is removed from the tube through an exit thereof. Ingress of air into the tube is inhibited by forming a plug of the biomass material at the entrance of the tube and a plug of ash at the exit of the tube. A neutral atmospheric pressure is maintained in the reactor tube relative to pressure outside the reactor tube by monitoring and adjusting a volumetric rate of the fuel gas mixture withdrawn from the reactor tube based on pressures at the entrance and the exit of the reactor tube.

A method for purifying and cooling biomass syngas. The method includes: 1) cooling biomass syngas to 520-580 C., and recycling waste heat to yield a first steam; then subjecting the biomass syngas to cyclone dust removal treatment; and further cooling the biomass syngas to a temperature of 210 C., and recycling waste heat to yield a second steam; 2) removing a portion of heavy tar precipitating out of the biomass syngas during the second-stage indirect heat exchange; 3) carrying out dust removal and cooling using a scrub solution, to scrub off most of dust, tar droplets, and water soluble gases from the biomass syngas after the heat exchange and dust removing treatment; and 4) conducting deep removal of dust and tar with a wet gas stream, to sweep off remains of dust and tar fog in the scrubbed biomass syngas.

A system for conducting high-temperature thermolysis of waste tires and rubber products are proposed. By using the system, the waste tires and rubber products may be recycled jointly and efficiently to produce hard carbon, a synthesis gas, and a thermolysis liquid, which may be used profitably for various purposes.

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.
