METHOD FOR PRODUCING PURE SUGAR SOLUTION, AND METHOD FOR PRODUCING CHEMICAL PRODUCT |
摘要 |
The invention provides a method that allows fermentation impeding substances that occur during production of a sugar from cellulose-containing biomass to be removed in an aqueous sugar solution production step, and also provides a method for long-term stable production of an aqueous refined sugar solution that is nearly free from fermentation impeding substances. The aqueous refined sugar solution production method using cellulose-containing biomass as feed material comprises: (1) a step of decomposing cellulose-containing biomass to produce an aqueous sugar solution, (2) a step of subjecting the aqueous sugar solution resulting from step (1) to coagulation treatment, (3) a step of subjecting the aqueous sugar solution resulting from step (2) to microfiltration and/or ultrafiltration to recover an aqueous sugar solution from the downstream side, (4) a step of subjecting the aqueous sugar solution resulting from step (3) to nanofiltration and/or reverse osmosis to recover an aqueous refined sugar solution from the upstream side while removing fermentation impeding substances from the downstream side,
