Processing thermogravimetric analysis data for isoconversional kinetic analysis of lignocellulosic biomass pyrolysis: Case study of corn stalk
TL;DR: In this paper, a detailed isoconversional kinetic analysis of TGA data obtained from the pyrolysis of corn stalks at five heating rates was presented, and the results have shown that the effective activation energies of corn stalk pyrotechnics vary from 148 to 473 kJ mol−1 when the conversion ranges from 0.05 to 0.85.
