The Complexity of Lignin Thermal Degradation in the Isothermal Context

Thermal degradation of lignin in nitrogen atmosphere is evaluated by linear heating and isothermal tests. While suggests that thermal decomposition the 200–400 °C range mainly consists a single step, careful analysis tests points to different fractions having stabilities. This an important point for practical predictions, since kinetics obtained as if degradations at temperatures were same would lack utility. Instead, stairway type are proposed evaluate rates sample quantities involved interest.
