A two-stage syngas production method to produce a final product gas from a carbonaceous material includes producing a first product gas in a first reactor, separating char from the first product gas to produce separated char and char-depleted product gas, and separately reacting the separated char and the char-depleted product gas with an oxygen-containing gas in a second reactor to produce a final product gas. The separated char is introduced into the second reactor above the char-depleted product gas. The solids separation device may include serially connected cyclones, and the separated char may be entrained in a motive fluid in an eductor to produce a char and motive fluid mixture prior to being transferred to the second reactor. A biorefinery method produces a purified product from the final product gas.

A process for the manufacture of one or more useful products comprises: gasifying a carbonaceous feedstock comprising waste materials and/or biomass in a gasification zone to generate a raw synthesis gas; supplying at least a portion of the raw synthesis gas to a clean-up zone to remove contaminants and provide a clean synthesis gas; supplying the clean synthesis gas to a first further reaction train to generate at least one first useful product and a tailgas; and diverting selectively on demand a portion of at least one of the carbonaceous feedstock, the clean synthesis gas, the tailgas and the light gas fraction to heat or power generation within the process, in response to external factors to control the carbon intensity of the overall process and enable GHG emission savings.

A gas generation plant for generating hydrogen-containing synthesis gas includes a gas generation reactor which is oriented in the vertical direction being greater in length vertically than width. A gas inlet is designed for the passage of superheated water vapor into the gas generation reactor. Through an upper outlet, a gas/water vapor mixture can exit the gas generation reactor and be reused in the second heating element after having been superheated. Synthesis gas can exit through a lower gas outlet. In the vertical direction, the gas inlet is arranged at a smaller distance from the lower end than the lower gas outlet. The upper gas outlet is arranged at a smaller vertical distance from the upper end than the lower gas outlet. The vertical distance between the upper gas outlet and the lower gas outlet is greater than the vertical distance between the lower gas outlet and the gas inlet.

The invention relates to a process and system for converting carbon material into power. Carbon material 12 is gasified into synthesis gas 18 in a gasifier 16, and steam 14 is supplied to the gasifier 16. The synthesis gas 18 is supplied to a gas turbine 30, 36, 38 to produce power. Air 24 is added to the synthesis gas 18 prior to the gas turbine 30, 36, 38. Exhaust gas 40 from the gas turbine 30, 36, 38 is cooled in a first cooling device 42 with water 46 to produce steam 52. The steam is used in at least one steam turbine to produce power 56 and the steam 58 from at least one steam turbine 56 is recycled to the gasifier 16.

Fuel and fuel additives can be produced by processes that provide Fischer-Tropsch liquids having high biogenic carbon concentrations of up to about 100% biogenic carbon. The fuels and fuel additive have essentially the same high biogenic concentration as the Fischer-Tropsch liquids which, in turn, contain the same concentration of biogenic carbon as the feedstock.
