Kinetics of CO_2-catalyzed hydrolysis of cotton cellulose to saccharides in hot compressed water

Kinetics of CO_2-catalysted hydrolysis of cotton cellulose to saccharides was experimentally investigated in hot compressed water.The effects of temperature and CO_2 pressure on the reaction products were also discussed.High temperature and CO_2 pressure increased the formation of saccharides,while accelerated the decomposition of glucose simultaneously.An isothermal kinetic model and an isobaric kinetic model for the hydrolysis of cotton cellulose were respectively given by correlation of the dynamic data with the relative standard deviations both less than ±15%.The model analysis shows that rising the reaction temperature properly is benefit for improving the selectivity of cotton cellulose to saccharides.
