An integrated plant to generate chemical grade syngas from a steam biomass reforming in a multiple stage bio reforming reactor for use with either a high temperature or low temperature Fischer-Tropsch synthesis process to produce fuel from biomass is discussed. The first stage has a reactor to cause a chemical devolatilization of a biomass feedstock from the biomass feedstock supply lines into its constituent gases of CO, H2, CO2, CH4, tars, chars, and other components into a raw syngas mixture. A second stage performs further reforming of the raw syngas from the first stage into the chemical grade syngas by further applying heat and pressure to chemically crack at least the tars, reform the CH4, or a combination of both, into their corresponding syngas molecules. The second stage feeds the chemical grade syngas derived from the biomass feedstock to the downstream Fischer-Tropsch train to produce the fuel from the biomass. One or more recycle loops supply tail gas or FT product back into the plant. 1.

Supercritical Water Gasification Process

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 COcondenses to a liquid. At this density and pressure, the COcan 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 COtrends if implemented on a global scale. 1.

Aspects provide for volatilizing a biomass-based fuel stream, removing undesirable components from the resulting volatiles stream, and combusting the resulting stream (e.g., in a kiln). Removal of particles, ash, and/or H2O from the volatiles stream improves its economic value and enhances the substitution of legacy (e.g., fossil) fuels with biomass-based fuels. Aspects may be particularly advantageous for upgrading otherwise low-quality biomass to a fuel specification sufficient for industrial implementation. A volatilization reactor may include a fluidized bed reactor, which may comprise multiple stages and/or a splashgenerator. A splashgenerator may impart directed momentum to a portion of the bed to increase bed transport via directed flow.

An integrated plant that includes a steam explosion process unit and biomass gasifier to generate syngas from biomass is discussed. A steam explosion process unit applies a combination of heat, pressure, and moisture to the biomass to make the biomass into a moist fine particle form. The steam explosion process unit applies steam with a high pressure to heat and pressurize any gases and fluids present inside the biomass to internally blow apart the bulk structure of the biomass via a rapid depressurization of the biomass with the increased moisture content. Those produced moist fine particles of biomass are subsequently fed to a feed section of the biomass gasifier, which reacts the biomass particles in a rapid biomass gasification reaction to produce syngas components.
