Title:
METHOD FOR PRODUCING COMPOSITION DERIVED FROM LIGNOCELLULOSE-BASED BIOMASS
Document Type and Number:
WIPO Patent Application WO/2017/057714
Kind Code:
A1
Abstract:
This method for producing a composition derived from lignocellulose-based biomass has: (A) a step for subjecting lignocellulose-based biomass to a hydrolysis treatment including mixing the lignocellulose-based biomass with an acid and steaming the mixture, to produce an acid-steamed product; (M) a step for subjecting the acid-steamed product to a drying treatment to volatize and remove fermentation-inhibiting substances; (N) a step for adding ammonia to the acid-steamed product subjected to the drying treatment to further reduce the amount of the fermentation inhibitory substances, and adjusting the pH of the steamed product subjected to the drying treatment; and (B) a saccharification step for producing, by using an enzyme, a saccharified liquid containing at least one of monosaccharides and oligosaccharides from the acid-steamed product after the addition of the ammonia, wherein a reduction target value of the contained amount of furfural in step (M) is set on the basis of a threshold below which furfural among fermentation-inhibiting substances does not inhibit fermentation, and a reduction in the amount of furfural at step (N), and a reduction target value of the water content of the acid-steamed product in step (M) is set on the basis of a correlation between the furfural content and the water content of the acid-steamed product.
