ABSTRACT:
Disclosed herein are supercritical fluid biomass conversion machines, systems, and methods for converting a wide range of biomass materials into a plurality of reaction products including fermentable sugars and various aromatic substances. In one embodiment, a method is disclosed that comprises the steps of: providing an extruder; conveying a mixture of the selected biomass material and water through the extruder and into a supercritical fluid biomass conversion zone; heating and further pressurizing the mixture within the supercritical fluid biomass conversion zone to yield at least supercritical water, wherein heat energy is supplied by means of an induction heating coil positioned circumferentially about the supercritical fluid biomass conversion zone; retaining the mixture within the supercritical fluid biomass conversion zone for a period of time sufficient to yield the plurality of reaction products; and separating the plurality of reaction products into at least a water soluble fraction and an organic solvent soluble fraction.
