Thermogravimetric spectra of binderless briquettes and its raw material, soybean crop residues, were critically
analyzed to ascertain the changes occurring in the intrinsic biopolymeric components such as hemicellulose, cellulose
and lignin due to briquetting stresses. Transitions of thermogravimetric signals and activation energy
levels were analyzed and discussed. The distinct and sharp signals related to the secondary charring process at
the high temperature regime in thermogravimetry were noticed in briquettes as compared to these signals in
raw residue. Integral isoconversional Friedman kinetics treatment was used to compute the conversion fraction
dependent activation energies. Deconvolution analysis of differential thermograms was done to diagnose the internal
thermogravimetric transformations. It established the lesser reactivity and better consolidation in case of
briquetted biofuel.
