Abstract: A method for separating hydrolysis product of biomass is provided. The method includes providing a mixture solution containing a hydrolysis product of biomass and a divalent metal salt, adjusting the pH value of the mixture solution to between 1-4.6, and performing a filtering procedure on the mixture solution using a nanofiltration membrane to obtain a concentrated solution and a filtrate, wherein the concentrated solution mainly includes the hydrolysis product of biomass and the filtrate mainly includes the divalent metal salt.

Abstract: Disclosed is a method of separating carbohydrate, including: mixing formic acid with heteropoly acid, chloride or bromide of lithium, magnesium, calcium, zinc, or iron, or combinations thereof to form a mixing liquid. The method also includes dissolving a cellulose biomass by the mixing liquid to form a solution, mixing water and the solution to hydrolyze the cellulose biomass for forming a carbohydrate solution, and mixing an extractant and the carbohydrate solution to extract the formic acid out of the carbohydrate solution. The heteropoly acid, the chloride or bromide of lithium, magnesium, calcium, zinc, or iron, or combinations thereof in the carbohydrate solution is separated out of the carbohydrate solution by ion exclusion chromatography separation to obtain a carbohydrate.
