摘要：用两步法水解糖化稻壳，研究了常压下的最佳工艺条件以及加压下的动力学行为。用ＨＣｌ２％和ＦｅＣｌ３３％的混合液作催化剂，当液固比为１：１５时，经２小时的常压反应，水解后的单糖产率最高可达３７．３％。加压水解动力学可以用一级不可逆连串反应方程式描述，计算值与实验数据拟合良好。从实验数据求出了稻壳水解及单糖分解的活化能，同时找出了水解速率常数与催化剂浓度的关系。
he optimal opration in atmospheric condition and kinetic behaviour under pressure on saccharification of rice husk in two-step hydrolysis reaction has been studied.The yield of monose is obtained as high as 37.3% after two hours' atmospheric hydrolysis with mixture of HCl 2% and FeCl33% as catalyst. under liquid-solid ratio of 15:1 (vol.). The model of first order irreversible series reaction has been employed to describe the hydrolysis kinetics. which can correlates the experimental data quite well. Activation energies for hydrolysis of rice husk and decomposition of monose have been calculated from experimental data. and relationship between rate constant and catalyst concentration has been established.
