Abstract:
In the present invention, a sugar alcohol can be efficiently produced from a cellulose-containing biomass by carrying out a step (1) of filtering an aqueous sugar solution, which is obtained by hydrolysis of a cellulose-containing biomass, by passing the solution through a separation membrane having a molecular cut-off of 300-800 so as to remove catalyst poisons to the non-permeate side and collecting a sugar solution from the permeate side, and a step (2) of subjecting the sugar solution obtained in step (1) to a hydrogenation reaction in the presence of a metal catalyst.

Claim (Index 1):
A method for producing a sugar alcohol from a cellulose-containing biomass as a raw material, comprising:\n step (1): a step of filtering a sugar aqueous solution obtained by hydrolysis of the cellulose-containing biomass, through a separation membrane having a molecular weight cut-off of 300 to 800 to remove a catalyst poison to a non-permeation side and collecting a sugar solution from a permeation side; and step (2): a step of subjecting the sugar solution obtained in the step (1) to a hydrogenation reaction in the presence of a metal catalyst.
