METHOD FOR ISOLATING CELLULOSE FROM A BIOMASS AND PRODUCTS PROVIDED THEREFROM

摘要

A pretreated biomass is subjected to high frequency pulses and shear forces without denaturing and/or degrading the individual components of the biomass. The biomass is then subjected to compressive force to separate a first liquid fraction from a first fractionated biomass. The first fractionated biomass may again then be subjected to the same high frequency pulses and shear forces as previously, particularly if there are hemicellulose and/or sugars still present in the first fractionated biomass. Compressive forces are used to separate a second liquid fraction from a second fractionated biomass. The second fractionated biomass is subjected to oxidation. The second fractioned biomass is then subjected to compressive forces to separate out one or more water insoluble components of the biomass in water soluble form and to provide cellulose that has not been denatured and/or degraded and has a lignin contact of less than 7 percent.
