Abstract
The invention relates to a process for producing xylose and cellulose from a biomass comprising: (a) mixing a biomass with a reactive fluid comprising water and a supercritical C1-C5 alcohol to form a mixture at a first temperature and a first pressure; (b) maintaining the mixture at the first temperature and first pressure for a first time period, wherein a reaction occurs; and (c) quenching the reaction to form at least one reaction product mixture; wherein xylose and cellulose are produced by the process. Lignin may also be produced by the processes of the invention.
