pyrolysis, cylindrical wood pieces of 20 mm diameter and 50 mm length is pyrolysed in a tube
furnace at temperatures ranging from 300oC to 500oC. Solid, liquid and gas products are collected
and the yields are calculated. For slow pyrolysis, thermogravimetric analysis (TGA) is used using
sawdust from the same biomass. Using the experimental data from two different methods the
kinetic parameters are calculated such as activation energy and pre-exponential factor for the two
different pyrolysis methods. For fast pyrolysis the parameters are found to be E = 32.5 kJ/mol and A
= 35/min and for slow pyrolysis Es = 50.48 kJ/mol and As = 3179.86/min. The large difference
between the values show that kinetic studies and modelling work using thermogravimetric analysis
data is not suitable for commercial scale simulation. Also, the pre-exponential value for fast
pyrolysis shows that the kinetic equation used from flash pyrolysis is not exactly suitable for this
situation. Therefore, it is recommended that more studies on the kinetic parameters of fast pyrolysis
of thermally thick biomass need to be done.
