Disclosed are methods for accommodating changes in the conditions of partial oxidation of hydrocarbonaceous feedstock by changing characteristics of the hot oxygen used in the partial oxidation.

Disclosed is a coupling system of biomass gasification and waste incineration. A carbon pipeline is communicated between a biomass carbon outlet of a circulating fluidized bed gasifier and an activated carbon injection port of a waste incineration assembly. The activated carbon generated by reaction in the circulating fluidized bed gasifier is sent to the activated carbon injection port through the carbon pipeline to capture harmful substances containing heavy metals and dioxins in flue gas generated by the waste incineration assembly. According to the present application, the activated carbon generated by the circulating fluidized bed gasifier is supplied to the waste incineration assembly, and a mutual coupling between the circulating fluidized bed gasifier and the waste incineration assembly is thereby realized, thus reducing the amount of the activated carbon additionally supplied to the wasted incineration assembly.

A system includes a gas turbine system having a compressor, a combustor, and a turbine, wherein the combustor is configured to combust fuel and oxidant in a substantially stoichiometric equivalence ratio, phi (), of between 0.95 to 1.05. The system further includes an exhaust gas recirculation (EGR) system configured to recirculate an exhaust gas from the turbine to an intake into the compressor. The system further includes a biochar pyrolysis reactor configured to heat a biomass feedstock to cause a pyrolysis reaction of the biomass feedstock using heat from the exhaust gas to generate a biochar and a syngas.

A synthesis gas production method from a biomass raw material includes: a synthesis gas production step of producing a synthesis gas that includes hydrogen, carbon monoxide, and carbon dioxide from a biomass raw material, water, and carbon dioxide that are supplied, wherein the carbon dioxide supplied to the synthesis gas production step includes the carbon dioxide in the synthesis gas.

The invention relates to the unique operation of a partial oxidation (POx) system by enabling simultaneous injection of feeds with widely varying properties, including simultaneous injection of gas, liquid and solid feedstocks to the hot oxygen burner.

The process described herein converts biomass directly into a combination of hydrogen, methane and carbon dioxide. A portion of the gases are collected at pressures above the thermodynamic critical pressure for water, which is 3200 psi (pounds per square inch). Typical operating pressure at the point where the first portion of gas collected can range from 3200 psi to 6000 psi. Upon cooling, most of the CO.sub.2 condenses to a liquid. At this density and pressure, the CO.sub.2 can be injected into a deep well aquifer to sequester the carbon dioxide. The overall process is superior to carbon neutral processes, can be carbon negative, and possesses the potential to reverse atmospheric CO.sub.2 trends if implemented on a global scale.

Methods and apparatuses for producing fuel and power from the reformation of organic waste include the use of steam to produce syngas in a Fischer-Tropsch reaction, followed by conversion of that syngas product to hydrogen. Some embodiments include the use of a heated auger both to heat the organic waste and further cool the syngas.
