    Abstract

    This thesis reports some insight into fundamental chemistry of cellobiose decomposition in hot-compressed water (HCW). This includes the effect of mild temperature, initial cellobiose concentration, weakly acidic condition and AAEM chlorides on decomposition behaviour of cellobiose. The new knowledge provides fundamental understanding on decomposition mechanisms of sugar oligomers into monomers and other products. Such knowledge is also essential to understanding the decomposition behaviour of more complex cellulose and biomass conversion in HCW.
