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:

Method of separating saccharides from aqueous product solution of cellulose hydrolysis process

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.

Method of separating carbohydrate

In an embodiment of the present disclosure, a sugar product and method for fabricating the same is provided. The method includes mixing an acid compound and lithium chloride, magnesium chloride, calcium chloride, zinc chloride or iron chloride or lithium bromide, magnesium bromide, calcium bromide, zinc bromide or iron bromide or heteropoly acid to form a mixing solution, adding a cellulosic biomass to the mixing solution for a dissolution reaction, and adding water to the mixing solution for a hydrolysis reaction to obtain a sugar product. The present disclosure also provides a sugar product fabricated from the method.

Sugar products and fabrication method thereof

In an embodiment of the present disclosure, a method for preparing a sugar is provided. The method includes mixing an organic acid and a solid acid catalyst to form a mixing solution, adding a cellulosic biomass to the mixing solution to proceed to a dissolution reaction, and adding water to the mixing solution to proceed to a hydrolysis reaction to obtain a sugar.

Method for preparing sugars

The disclosure provides a method for liquefying biomass, including: (a) mixing a solid organic ammonium salt containing single nitrogen with at least one organic compound which is capable of forming a hydrogen bond with the solid organic ammonium salt to form a first mixture; (b) heating the first mixture until the first mixture becomes a solution; (c) mixing a biomass and an acid catalyst with the solution to form a second mixture; and (d) heating the second mixture to make the biomass therein convert into a liquefied product.

Method for liquefying biomass

A method of preparing furfural compounds and a mixture for preparing the same are disclosed. First, a solution is prepared by mixing an organic ammonium salt and a hydroxyl organic solvent. Then, a carbohydrate is mixed with the solution to form a mixture. The mixture is heated to a reaction temperature for conversion of the carbohydrate to produce the furfural compounds.

The apparatus includes a reaction area including a first organic layer including sugar and a solvent and a second organic layer including a solvent mixture with azeotropy and extractability, a boiling area including a mixing solution formed by the hydroxymethylfurfural and the solvent mixture, connected with the reaction area, and a distilling area including water and a liquid layer including the solvent mixture, connected to the reaction area. In another embodiment of the invention, a method for preparing hydroxymethylfurfural (HMF) is provided.

Method and apparatus for preparing hydroxymethylfurfural

The present invention discloses a process for preparing a hydrophobic fluid containing metal oxide nanoparticles dispersed therein such as heat transfer fluids or lubricant fluids, including introducing an alkaline aqueous solution (aqueous phase) and an organic solution of an organic acid metal salt (hydrophobic phase) into a rotating packed bed, the two solutions flowing radially through the rotating packed bed under a great centrifugal force, so that the aqueous phase and the hydrophobic phase contact with each other, reactants in the two phases undergo reactions at the interface of the two phases rapidly, and thus metal oxide nanoparticles are formed. The metal oxide nanoparticles stably dispersed in the hydrophobic phase, which is nanofluid.
