Title:
PROCESS FOR PRODUCTION OF MONOSACCHARIDE AND PROCESS FOR PRODUCTION OF ETHANOL BOTH UTILIZING CELLULOSE-BASED SUBSTANCE
Document Type and Number:
WIPO Patent Application WO/2009/005168
Kind Code:
A1
Abstract:
Disclosed is a novel process which has low facility load, requires a reduced amount
of energy, is highly safe, and enables to produce a monosaccharide such as glucose
and xylose by decomposing a cellulose-based substance under conditions where
a substance used for decomposing the cellulose-based substance (e.g., a solvent,
a catalyst) can be separated, collected and re-used readily. Also disclosed
is a novel process for producing ethanol from the monosaccharide through ethanol
fermentation. Specifically disclosed is a process for producing a monosaccharide,
which comprises disaggregating/finely pulverizing a cellulose-based substance,
mixing the resulting material with a phosphate solution to disperse the resulting
material in the phosphate solution, and decomposing cellulose in the solution
at a temperature of 100˚C or lower while irradiating with ultraviolet
ray optionally in the presence of titanium dioxide.
