NOVELTY - Converting a selected biomass material into reaction products includes providing (501) an elongated biomass conveying zone; conveying (502) a mixture of the selected biomass material and water through the elongated biomass conveying zone and into the supercritical fluid biomass conversion zone; heating and pressurizing (503) the mixture; retaining (504) the mixture within the supercritical fluid biomass conversion zone for 0.4-10 seconds; expelling (505) the reaction products; and separating (506) the reaction products into a water soluble fraction and an organic solvent soluble fraction.    USE - Method for converting a selected biomass material into reaction products (claimed) including fermentable sugars and aromatic compounds which can be converted into cellu-ethanol and ligno-diesel.    ADVANTAGE - The method enhances the rapid cleavage and depolymerization of various giant biomass molecules into their more fundamental simple sugars and aromatic compound chemical building blocks.    DETAILED DESCRIPTION - Converting a selected biomass material into reaction products comprises:    (A) providing (501) an elongated biomass conveying zone that contains at least two elongated rotatable shafts having righted screws positioned lengthwise within an elongated conveying section housing, where the flighted screws are positioned on each respective shaft, and the shafts continuously convey the selected biomass material together with water from an upstream biomass inlet to a supercritical fluid biomass conversion zone while increasing the pressure of the selected biomass material and water from atmospheric at the biomass inlet to greater than 22.1 MPa at the supercritical fluid biomass conversion zone;    (B) conveying (502) a mixture of the selected biomass material and water through the elongated biomass conveying zone and into the supercritical fluid biomass conversion zone;    (C) heating and pressurizing (503) the mixture within the supercritical fluid biomass conversion zone to yield supercritical water, where heat energy is supplied by use of an induction heating coil positioned circumferentially on the supercritical fluid biomass conversion zone;    (D) retaining (504) the mixture within the supercritical fluid biomass conversion zone for 0.4-10 seconds to yield the reaction products;    (E) expelling (505) the reaction products out of the supercritical fluid reaction zone and into a quenching/separation zone; and    (F) separating (506) the reaction products into a water soluble fraction and an organic solvent soluble fraction.
