摘要: For the purpose of hydrolysing hemicelluloses to oligomers and monomers, Sesbania grandiflora samples were subjected isothermal autohydrolysis in temperatures ranging from 145 °C 190 °C, using a solid liquid ratio 8 reaction times up 7.5 h. Kinetic models based on sequential pseudo-homogeneous first order Kinetics with Arrhenius type temperature dependence employed for describing time course main compounds their degradation products. The hydrothermal treatment results show that can be as an alternative raw material production XOS leading high concentrations (14.1 g/L experiment carried out at 0.1 h) xylan conversion (62.6% 6 min). model proposed provides satisfactory interpretation experimental data obtained treatments this study.
