Decomposition Characteristics of Wood Using Supercritical Methanol for Biodiesel Production

Abstract:

In this work, the decomposition characteristics of wood using supercritical methanol have been studied. The kinetic analysis was carried out for three heating rates of 5.2, 11.6 and 16.3 oC/min. And the liquid products analysis has been performed for reaction temperatures of 300-320 oC and reaction times of 0-120 min, respectively. The activation energies of wood decomposition in supercritical methanol were 45.2-48.8 kJ/mol, depending on the heating rates. And the reaction orders were 0.25 for all heating rates. And the liquid product has been analyzed by GC-MS. From this work, the yields of liquid product increased as increasing of reaction temperature and reaction time. And it was also found that the components of liquid products were mainly acetic acid, latic acid, pentanol and phenol.
