Abstract: A mixture of 1.0% FeCl_3 and 1.0% HCI is found to be the best catalyst for saccharification of bagasse by two-step hydrolysis reaction, in which even at low tempera-ture the yield of sugar is high. Reaction kinetics of bagasse hydrolysis is studied with in-organic salts as catalyst. Kinetic equation is obtained which is Suitable for describing the saccharification reaction of bagasse at both atmospheric and high pressure. Also this equa-tion correlates experimental data very well. Activation energies are calculated for saccha-rification of bagasse and decomposition of sugar.
