1 INTRODUCTIONBiomass continues to be an important candidate asa renewable resource for energy chemicals,and feed-stock.This makes cellulose,which is the major com-ponent of biomass,an important compound to study.Near-critical water (NCW) is usually referredto hot compressed water in the range of 250--350℃,which has changing properties as temperature goes upsubstantially. NCW has a strong tendency to ionizeand can act as an effective acid and base catalysts.
