Modelling and Simulation of Pyrolysis of Teak (Tectona Grandis) Sawdust

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.
