Lignocellulosic composition based thermal kinetic study of Mangiferaindica Lam, Artocarpus Heterophyllus Lam and Syzygium Jambolana seeds

In the present study, pyrolysis of mangifera indica L., Artocarpus heterophyllus L. and jambolana seeds have been performed using thermogravimetric analysis. These biomasses have enriched lignocellulosic composition of hemicellulose (5-10%) and lignin (1-3%) which are unexplored. The TGA analysis was performed at various heating rates of 10, 15, 20, 25 and 30 degrees C/min from 25 to 600 degrees C. Kinetic investigation of the pyrolysis method using TGA statistics has been done using iso-conversional models of Flynn-Wall-Ozawa, Kissinger-AkahiraSunose, Vyazovkin and Vyazovkin AIC. The apparent activation energies value ranged from 179.86 to 226.31 kJ/ mol in the fractional conversion range of 0.1 to 0.7.

Automated summary

This study investigated the pyrolysis of mangifera indica L., Artocarpus heterophyllus L., and jambolana seeds, revealing their rich lignocellulosic composition and varying apparent activation energies during pyrolysis at different conversion rates.
