摘要

Abstract

The decomposition kinetics of glucose was studied in high-temperature liquid water(HTLW) from 180 to 220℃ under a pressure of 10 MPa.It was found the main products from glucose decomposition were 5-hydroxymethylfurfural(5-HMF)and levulinic acid(LA).The decomposition kinetics of 5-HMF and stability of LA in HTLW were further investigated.A kinetic model for glucose decomposition was proposed accordingly.In the model

a series of first-order reactions with the consideration of parallel by-reactions were used to illustrate the decomposition of glucose.The decomposition activation energies of glucose

5-HMF

and LA were evaluated as 118.85

95.40

and 31.29 kJ·mol

-1

respectively.
