“…In this work, biomass samples such as bagasse, coir pith, groundnut shell and casuarinas leaves are taken for study. Earlier, researchers have tried with biomass such as rice husk, rice‐straw, coir pith, corn‐stover, wheat straw, rapeseed, saw dust, larch bark, palm oil fibers for TGA studies . The chosen biomass samples are first analyzed for its moisture content.…”

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°C at a heating rate of 10°C/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. © 2013 American Institute of Chemical Engineers Environ Prog, 33: 256–266, 2014

“…Kumar et al [17] and Sheeba et al [19] have reported three distinct stages/zones of mass loss in the TG of corn stover and Coir pith respectively. The kinetic parameters for these stages/zones were determined by these authors and it was found the first zone to be close to a zero-order reaction while the second stage/zone was very close to a first-order reaction, similar to the above observations.…”

“…This thermal decomposition behaviour of any biomass can be analyzed by a Thermogravimetric apparatus with high accuracy and precision. Use of TG for analysis of such thermal behaviour and determination of kinetics is well established in literature [17][18][19]. TG records can quantitatively resolve complex mixtures because of the characteristic thermal decomposition temperature of each component [20].…”

Lignin, cellulose and hemicellulose are the major components of biomass. The chemical reactivities of the biomass are affected by the difference in chemical structures making the knowledge of their composition, essential to predict the efficiency of the biomass conversion process for utilizing bio-energy, which is of immense importance for successful commercialization of these processes and thus to gain energy security. Despite the presence of accurate and robust Wet Chemical methods, it is very difficult to implement these techniques commercially. Therefore, in this study the chemical composition of biomass has been determined by a simpler physical technique-Thermogravimetric Analysis (TG). The values obtained were correlated with chemical methods and it was found that TG predicted the holocellulose content with a relatively high accuracy while it underestimated the lignin content by a huge margin. The kinetic parameters of degradation of five biomass samples have also been reported in this study. This study also compared the mass loss profiles of the biomass in TG with their mass loss profiles in a furnace.
