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 The fuel gas mixture is withdrawn from the tube and the ash is removed from the tube through an exit thereof.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relative to pressure outside the reactor tube by monitoring and adjusting a volumetric rate of the fuel gas mixture withdrawn from the reactor tube based on pressures at the entrance and the exit of the reactor tube.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 system for waste processing includes a feeder for receiving a waste stream of carbonaceous materials, multiple independently controllable augers, a reactor and an incinerator. The reactor receives a waste stream from the feeder and using a controllable heating element assembly converts the carbonaceous materials in the waste stream to syngas. The incinerator uses the syngas from the reactor to incinerate separately received black water waste from a storage tank.

A process for the gasification of a solid carbonaceous feed, the process comprising the steps of: introducing a batch of the solid carbonaceous feed into a sluice vessel, while an internal pressure in the sluice vessel is at a first pressure; introducing at least recycled CO2 into the sluice vessel via one or more gas inlets covered by the solid carbonaceous feed, to pressurize the sluice vessel from the first pressure to a second pressure exceeding the first pressure, during a predetermined time period; closing the one or more gas inlets; opening a feed outlet of the sluice vessel to supply the batch of the solid carbonaceous feed to a feed vessel for feeding the solid carbonaceous feed to a gasification reactor; closing the feed outlet; venting the sluice vessel to reduce the internal pressure to the first pressure; and repeating the process.

A solid and liquid waste gasifier has a reactor that includes a fixed chamber and an alumina (aluminium oxide) refractory coating, provided with an automatic energy cell feeder and having, inside the fixed chamber, a rotary steel tube which is coupled to one of the ends of the fixed chamber, said rotary tube having a surface containing holes, a screw on its inside surface and a second screw on its outside surface, which rotates juxtaposed to the inside tubular body wall, ensuring the ashes are moved to be released in an automatic device, said gasifier being provided with sensors, the data from which is sent to a programmable logic controller for activation of the mechanical elements.

A process for processing carbonaceous material, the process comprising delivering a carbonaceous material to a first reactor zone; delivering a catalyst to the first reactor zone; processing the carbonaceous material within the first reactor to decompose and/or devolatilise at least a portion of the carbonaceous material; delivering an output from the first reactor to a secondary reactor; the secondary reactor having a higher temperature than the first reactor.

A biomass gasification system. The system includes: a) a gasifier; b) a waste heat exchanger; c) a waste heat boiler; d) a cyclone separator; e) a gas scrubber; f) a shift reactor; g) a desulfurizing tower; h) a first decarburizing tower; i) a synthesizing tower; and j) a second decarburizing tower. In the system, the gasifier, the waste heat exchanger, the cyclone separator, the gas scrubber, the shift reactor, the desulfurizing tower, the first decarburizing tower, the synthesizing tower, and the second decarburizing tower are connected sequentially. In addition, CO.sub.2 outlets of the first decarburizing tower and the second decarburizing tower are both connected to a cold medium inlet of the waste heat exchanger; and a cold medium outlet of the waste heat exchanger is connected to a gasifying agent entrance of the gasifier.

A system for processing material for a gasifier. The system comprises an auger feeder adapted to receive material to be gasified. The auger feeder is adapted to feed the material. In an exemplary embodiment, a tube is connected to the auger feeder such that the tube is adapted to receive the material from the auger feeder. In such an embodiment, the tube is also connected to a gasifier, which is adapted to receive the material from the tube.

A thermochemical system & method may be configured to convert an organic feedstock to various products. A thermochemical system may include a solid material feed module, a reactor module, an afterburner module, and a solid product finishing module. The various operational parameters (temperature, pressure, etc.) of the various modules may vary depending on the desired products. The product streams may be gaseous, vaporous, liquid, and/or solid.

A pressurizing nozzle includes a nozzle body; a filter that is provided to be perpendicular to the central axis direction of the nozzle body so as to cover the internal cross section of the nozzle body at the leading end portion on one end of the nozzle body and that is made of sintered metal having a prescribed thickness in the central axis direction; a retainer having an annular shape that is mounted to the leading end portion of the nozzle body so as to be disassemble and that fixes the outer circumferential portion of the filter via a pair of sealing parts; and a sealing portion that is disposed along the outer circumferential end face of the filter and that seals a fluid from flowing from the outer circumferential face toward the outside in the radial direction through the filter.
