Disclosed is a device for treating high-concentration organic wastewater by catalyst hydrothermal gasification, including a CHG reactor, a temporary wastewater storage tank and a condensing heat exchanger which are sequentially in loop connection. The CHG reactor includes a shell, a thermocouple, a water distribution device, and a packing support. The device of the present disclosure can quickly convert the high-concentration organic wastewater into clean energy or harmless gas at a low temperature under the action of a catalyst, so that the energy consumption of a treatment process is greatly reduced, and the treatment efficiency is improved. The device has potential application prospect.

A reactor system made up of a single canister or a plurality of separate canister sections for the advanced thermal chemical conversion processing of municipal solid waste (“MSW”), either sorted or unsorted, and autoclaves specially designed to process the waste at suitable temperature and pressure combinations is disclosed. The canister sections can be individually and separately filled with compressed bales of MSW or with selected loose MSW. The reactor system can produce syngas that has an enhanced BTU value, typically between about 300 to 700 BTU/ft.sup.3. The remainder solid waste material generally amounts to approximately 5% of the original MSW volume. This material can then be sorted for metals with the balance being sent to a landfill or other recycling processes depending on its composition.

The present invention discloses a system and method for supercritical water gasification (SCWG) of biomass materials wherein the system includes a SCWG reactor and a plurality of heat exchangers located within a shared pressurized vessel, which decouples the function of containing high pressure from the high temperature function. The present invention allows the heat transfer function to be conducted independently from the pressure transfer function such that the system equipment can be designed and fabricated in manner that would support commercial scaled-up SCWG operations. By using heat exchangers coupled to the reactor in a series configuration, significant efficiencies are achieved by the present invention SCWG system over prior known SCWG systems.

An ASG system for polygeneration with CC includes a devolatilizer that pyrolyzes solid fuel to produce char and gases. A burner adds exothermic heat by high-pressure sub-stoichiometric combustion, a mixing pot causes turbulent flow of the gases to heat received solid fuel, and a riser micronizes resulting friable char. A devolatilizer cyclone separates the micronized char by weight providing micronized char, steam and gases to a gasifier feed and oversized char to the mixing pot. An indirect fluid bed gasifier combustion loop includes a gasifier coupled to the gasifier feed, a steam input to provide oxygen for gasification and to facilitate sand-char separation, and an output for providing syngas. A burner provides POC to a mixing pot which provides hot sand with POC to a POC cyclone via a riser, where the POC cyclone separates sand and POC by weight and provides POC and sand for steam-carbon reaction.
