Determination of Kinetic Parameters of Biomass Samples Using Thermogravimetric Analysis

摘要

In this work, thermogravimetric analysis is carried out on four different biomass samples such as bagasse, coir-pith, groundnut shell and casuarina leaves to study their thermal behaviour. Analysis is put through in an inert nitrogen atmosphere from ambient temperature to 800℃ at a heating rate of 10℃/min. Three reaction zones corresponding to dehydration, hemicellulose-cellulose degradation and lignin degradation are observed for all four biomass samples. The kinetic parameters such as activation energy, pre-exponential factor and order of the reaction for all the components of samples are determined using the simple Arrhenius equation.
