Method for producing water-insoluble liquefied fuel oil from biomass

A method for producing a water-insoluble liquefied fuel oil containing a hydrocarbon, comprising the steps of: subjecting a mixture that contains biomass containing lignocellulose, an organic solvent, and water to liquefaction; simultaneously with or after liquefaction, causing a mixture of the liquefied fuel oil that contains the organic solvent and an aqueous phase that contains a water-soluble organic substance to come into contact with a dehydration catalyst under pressure and then subjecting the resultant to dehydration, or causing the mixture of a liquefied fuel oil that contains the organic solvent and an aqueous phase that contains a water-soluble organic substance to come into contact with hydrogen in the presence of a hydrogenation catalyst under pressure, and then subjecting the resultant to hydrogenation; and separating a water-insoluble liquefied fuel oil from the mixture after dehydration or hydrogenation, wherein the dehydration catalyst or hydrogenation catalyst is a zeolite catalyst or a Pd/Al2O3 catalyst.

A method for producing a water-insoluble liquefied fuel oil, comprising the steps of: subjecting a mixture that contains biomass containing lignocellulose, an aromatic hydrocarbon solvent, and water to liquefaction; causing the liquefied fuel oil that contains the aromatic hydrocarbon solvent after liquefaction to come into contact with a dehydration catalyst under pressure and then subjecting the resultant to dehydration; and separating a water-insoluble liquefied fuel oil from the mixture after dehydration, wherein the dehydration catalyst is a zeolite catalyst or a Pd/Al2O3 catalyst.
