The Pyrolysis Kinetics of a Single Wood Particle

• Experimental results from birchwood and pinewood pyrolysis in a new single particle reactor are presented. Apparent lunetic parameters for the mass-loss of wood particles (5-800 mg) at temperatures from 300 to 860°C are determined. Kinetic parameters for the evolution of CO, CO2, H2O, H2 and CH4, are also established. The drylng process was examined and it was found that drying and pyrolysis increasingly overlap in time as temperature rises and that the overlap is substantial above 450 °C.
