【 摘 要 】

References(24)The present study determines the kinetics for decomposition of mannose, its corresponding uronic acid (mannuronic acid (MA)), and sugar alcohol (mannitol) under hydrothermal condition. The experimental work was conducted using a continuous-flow-reactor at temperatures ranging from 170 to 250°C, and with residence time between 3 and 15 s. The operating pressure was fixed at 25 MPa throughout the experiment. The remaining amount of all compounds decreased as the temperature increased. The decomposition reaction followed first order kinetics at shorter residence times. The decomposition rate increased in the order of MA
