Kinetics of Xylan Hydrolysis Under Electron Beam-Hydrothermal Coupled Treatment
Listed in ScienceDB
This study investigates the effects of electron beam (EB) irradiation on xylan's molecular weight and pyrolysis characteristics, along with its hydrolysis kinetics under the combined influence of irradiation and hydrothermal treatment.
Description
Xylan was irradiated with EB, and the hydrolysis kinetics of xylan pretreated at 160 ℃ to 180 ℃ using hydrothermal methods were systematically analyzed. A biphasic hydrolysis kinetic model was utilized for the fitting analysis.
Results indicate that irradiation induces depolymerization of xylan, resulting in decreased molecular weight and thermal stability. During the coupled EB-hydrothermal treatment, higher hydrothermal temperatures increased both the fraction of fast-hydrolyzing xylan (α) and its rate constant (ki). After irradiation, both α and ki significantly increased, while the activation energy (Ea) decreased.

The activation energy for fast-reacting xylan decreased from 44.57 kJ/mol to 39.19 kJ/mol, while for slow-reacting xylan, it fell from 141.74 kJ/mol to 121.26 kJ/mol. The model fits the experimental data well, offering theoretical insights for designing EB-hydrothermal treatment systems for xylan.
