Pyrolysis characteristics and kinetics behavior analysis of bamboo powder using TG-FTIR

  • Received Date: 2020-06-05
  • The pyrolysis gas release behavior and pyrolysis kinetics characteristics of bamboo powder were investigated by using TG-FTIR instrument and distributed activation energy model (DAEM) under a wide range of heating rates (20 ℃/min,50 ℃/min,and 100 ℃/min).The results showed that the pyrolysis process of bamboo powder experienced three stages,that was,the preheating drying stage,fast degradation stage and carbonization stage.The pyrolysis weight loss curve and differential weight loss curve shifted to the high temperature side with the increase of heating rate.The maximum of mass loss rate also increased as the heating rate increased,which was conducive to the full release of volatile components.The prominent volatile components released during the pyrolysis process of bamboo were CO2,aldehydes,ketones,organic acids and aromatic hydrocarbon,alkanes,phenols,etc.The activation energies fluctuated obviously with the conversion degree.The activation energies increased gradually with conversion degree during 0.10 and 0.25.During 0.25 and 0.80,the decomposition of cellulose/lignin and secondary decomposition of coke occurred,and the activation energies ranged from 219.7 kJ/mol to 268.8 kJ/mol.
