Abstract
Pyrolysis is used to produce bio-char, bio-oil and syngas from industrial residues
through thermochemical processing route. Pyrolysis decomposes biomass at an
elevated temperature in an inert atmosphere. The aim of this study is to develop a
model and evaluate activation energy for pyrolysis of teak sawdust. Teak sawdust
was pyrolysed at four different temperatures from 300 to 600
C. The mathematical model was developed for pyrolysis of teak sawdust. Kinetic constants were
calculated by fitting the data from pyrolysis experiments to the model. Activation
energy was determined from Arrhenius equation which related kinetic constant
and temperature. The results reveal that pyrolysis of waste biomass, teak sawdust,
could be the effective thermochemical route for bioenergy.

12.1 Introduction
Thermochemical biomass conversion processes involve the production of high
energy products from biomass by the application of heat and chemicals. They do
not produce direct useful energy products. They produce energy carriers, such as
producer gas, oils or methanol, under controlled temperature and oxygen conditions.
