Abstract: In a method, a cellulose component is separated from plant materials consisting of cellulose, hemicellulose and lignin as principal components. The method includes the step of: rinsing the plant materials into a separating agent comprising ethylene glycols, heating the separating agent with the plant materials up to a high temperature less than the boiling point of the separating agent and reacting the separating agent with the plant materials, evaporating the hemicellulose from the separating agent reacted with the plant materials while dissolving the lignin of the plant materials into the separating agent, finally collecting the remaining cellulose component of the plant materials floating on the surface of the separating agent.

Abstract: A method for manufacturing a biofuel includes; a step of adding an alkaline agent to a culture fluid in which an algae is cultured and infusing medium quality oil thereto, thereby generating and floating an emulsion; a step of evaporating moisture from the floated emulsion in a vacuum, thereby obtaining a fat and oil component and a solids of the algae and medium quality oil and filtering, thereby separating the fat and oil component of the algae, the medium quality oil and the solids; a step of fractionally distilling the separated fat and oil component of the algae and the separated medium quality oil, thermally decomposing the fractionally-distilled components by adding an alkaline agent thereto, thereby obtaining a pyrolysis oil and a pyrolysis residue, and fractionally distilling the pyrolysis oil into thermally-decomposed gas, light crude oil, medium quality oil and heavy quality oil; and a step of removing an impurity from the fractionally-distilled medium quality oil by means of solvent extraction, th

Abstract: A method for separating cellulose from a wood-based raw material including hemicellulose, cellulose, and lignin as principal components, includes injecting the wood-based raw material into a dissolution reservoir in which ethylene glycol is stored as a separating agent, and heating the separating agent in the dissolution reservoir at atmospheric pressure to a temperature in a range of 260° C. to 280° C., and reacting the wood-based raw material with the separating agent, evaporating a hemicellulose component from the separating agent and condensing the hemicellulose component, and monitoring a pH value of the condensate of the hemicellulose component. A temperature of the condensate is held at the temperature at which a change in the pH value of the condensate decreases, lignin is dissolved in the separating agent, and crude cellulose that floats in the separating agent is separated and collected.

Abstract: A method for separating cellulose from a wood-based raw material including hemicellulose, cellulose, and lignin as principal components, in which the wood-based raw material is injected into a dissolution reservoir 1, 100, 300 in which ethylene glycol is stored as a separating agent, and the separating agent in the dissolution reservoir is heated at normal pressure to a temperature in a range of 260° C. to 280° C., and the wood-based raw material is reacted with the separating agent, a hemicellulose component that evaporates from the separating agent is condensed, a pH value of a condensate which changes from an acid value to a neutral value as a temperature of the separating agent increases is monitored, a temperature of the condensate is held at a temperature at which a change in the pH value of the condensate decreases, lignin is dissolved in the separating agent, and crude cellulose that floats in the separating agent is separated and collected.
