PROCESS FOR TREATING LIGNOCELLULOSIC BIOMASS

---

Abstract

---

A process for treating lignocellulosic biomass is described. The process includes treating particulate biomass with alkali to partially remove hemicellulose sheath on cellulose microfibrils of the biomass; and carrying out an oxidation reaction on the alkali treated biomass to form a treated biomass having a disrupted cellulose crystalline structure. The treated biomass may be further processed to form free sugars and lignin and the free sugars can be used to produce bio-ethanol or used as sugar source in fermentation processes.
