Title:
PROCESS FOR PRODUCTION OF AQUEOUS REFINED SUGAR SOLUTION
Document Type and Number:
WIPO Patent Application WO/2011/162009
Kind Code:
A1
Abstract:
Disclosed is a method for producing an aqueous refined sugar solution, in which a biomass residue produced in a step of producing a sugar from a cellulose-containing biomass is removed in a step of producing an aqueous sugar solution, thereby preventing the clogging of a microfiltration membrane and/or an ultrafiltration membrane and producing the aqueous refined sugar solution steadily for a long period. Specifically disclosed is a process for producing an aqueous refined sugar solution using a cellulose-containing biomass as a raw material, which comprises the steps of: (1) decomposing the cellulose-containing biomass to produce an aqueous sugar solution; (2) causing the aggregation in the aqueous sugar solution produced in step (1) with an aggregating agent to produce an aqueous sugar solution having an average particle diameter of 2 μm or more as measured by a particle size distribution method; and (3) allowing the aqueous sugar solution produced in step (2) to pass through a microfiltration membrane and/or an ultrafiltration membrane to filtrate the aqueous sugar solution and collecting an aqueous sugar solution from the permeated side of the microfiltration membrane and/or an ultrafiltration membrane.
