    摘要： A method of separating a saccharide from an aqueous product solution of the cellulose hydrolysis process is provided. The aqueous product solution comprises a saccharide and a cellulose swelling agent. The cellulose swelling agent is zinc chloride, magnesium chloride or a combination thereof. The method comprises the following steps in the given order: (a) adding a first tertiary amine and an optional first organic solvent to the aqueous product solution to provide a mixture; (b) performing a solid-liquid separation to obtain a solution from the mixture; and (c) performing a liquid-liquid extraction by adding a second tertiary amine and a second organic solvent to the solution, and then removing the organic phase and collecting the aqueous phase, wherein the first tertiary amine and the second tertiary amine are the same or different, and the first organic solvent and the second organic solvent are the same or different.

    摘要： A saccharified solution production method includes: a saccharifying step of saccharifying hemicellulose or cellulose contained in cellulosic biomass to C5 or C6 saccharides by subjecting a slurry of cellulosic biomass to a hot water treatment in a supercritical state or subcritical state; a washing step of successively washing a solid in the slurry with washing water after the saccharifying step, by using multiple stages of thickeners for washing arranged in series so that the direction of movement of the solid in the slurry and the direction of movement of overflow water are opposite to each other; and a concentration step of removing a solid residue from the washing water recovered in the washing step by using a thickener for still standing that is different from the thickeners for washing, and then concentrating a supernatant of the thickener for still standing by using a concentration device to give a saccharified solution.
