A biorefining method of processing a lignocellulosic biomass to separate lignin and hemicellulose from cellulose includes the steps of (a) reacting the biomass in an aqueous slurry having a pH less than 7, comprising a transition metal catalyst, hydrogen peroxide; and (b)

separating a solid cellulose fraction from dissolved lignin and hemicellulose fractions. The method may also be used to treat cellulose and produce microcrystalline or nanocrystalline cellulose. The transition metal catalyst may be a nanoparticulate catalyst including multivalent iron, iron oxides and iron hydroxides. The nanoparticulate catalyst may be formed by oxidizing a highly reduced solution of iron, such as groundwater that has not been exposed to oxygen.

ABSTRACT A BIOREFINING METHOD OF PROCESSING A LIGNOCELLULOSIC BIOMASS TO SEPARATE LIGNIN AND HEMICELLULOSE FROM CELLULOSE INCLUDES THE STEPS OF (A) REACTING THE BIOMASS IN AN AQUEOUS SLURRY HAVING A PH LESS THAN 7, COMPRISING A TRANSITION METAL CATALYST, HYDROGEN PEROXIDE; AND (B) SEPARATING A SOLID CELLULOSE FRACTION FROM DISSOLVED LIGNIN AND HEMICELLULOSE FRACTIONS. THE METHOD MAY ALSO BE USED TO TREAT CELLULOSE AND PRODUCE MICROCRYSTALLINE OR NANOCRYSTALLINE CELLULOSE. THE TRANSITION METAL CATALYST MAY BE A NANOPARTICULATE CATALYST INCLUDING MULTIVALENT IRON, IRON OXIDES AND IRON HYDROXIDES. THE NANOPARTICULATE CATALYST MAY BE FORMED BY OXIDIZING A HIGHLY REDUCED SOLUTION OF IRON, SUCH AS GROUNDWATER THAT HAS NOT BEEN EXPOSED TO OXYGEN. (FIG. 26)
