NOVELTY - Making biofuels from plant matter, comprises: e.g. adding first solvent set comprising ethanol, to plant biomass to generate first solid biomass fraction and first liquid fraction; separating first solid biomass fraction from first liquid fraction; combining first solid biomass fraction with second solvent set, to generate second solid biomass fraction and second liquid fraction; separating second solid biomass fraction from second liquid fraction; and combining second solid biomass fraction with third solvent set to generate third solid biomass fraction and third liquid fraction.    USE - The method is useful for making biofuels including jet fuel blend stock and diesel blend stock (claimed).    ADVANTAGE - The method: enables recycling of the solvent, and recycling of first liquid fraction, second liquid fraction and third solid biomass fraction respectively comprising proteins, polar lipids and carbohydrates into animal feed, human food and nutraceutical product, and provides the biofuels with high yield and purity, thus it is highly efficient; and eliminates the use of an energy intensive drying step, hence reduces both capital and operating costs.    DETAILED DESCRIPTION - Making biofuels from plant matter, comprises: adding an first solvent set comprising ethanol (1 part by weight) to a plant biomass (1 part by weight), to generate a first solid biomass fraction and a first liquid fraction comprising proteins; separating the first solid biomass fraction from the first liquid fraction; combining the first solid biomass fraction (1 part by weight) with a second solvent set comprising ethanol (1 part by weight), to generate a second solid biomass fraction and a second liquid fraction comprising polar lipids; separating the second solid biomass fraction from the second liquid fraction; combining the second solid biomass fraction (1 part by weight) with a third solvent set comprising ethanol (1 part by weight) to generate a third solid biomass fraction and a third liquid fraction comprising neutral lipids; separating the third solid biomass fraction from the third liquid fraction, where the third solid biomass fraction comprises carbohydrates and the plant cells of the third solid biomass fraction are substantially intact; esterifying the neutral lipids with a catalyst in the presence of an alcohol; separating a water soluble fraction comprising glycerin from a water insoluble fraction comprising fuel esters; distilling the fuel esters under vacuum to obtain 16C or shorter fuel esters fraction, 16C or longer fuel ester fraction, and a residue comprising carotenoids and omega -3 fatty acids; and hydrogenating and deoxygenating at least one of the 16C or shorter fuel esters to obtain a jet fuel blend stock, or the 16C or longer fuel esters to obtain a diesel blend stock.
