Pyrolytic degradation of peanut shell: Activation energy dependence on the conversion.

•This study provides a thermo-kinetic approach on peanut shell pyrolysis.•Pyrolytic breakdown of solid peanut shell is independent of the heating rate.•This study helps to predict the extent of conversion at certain temperature.•Pyrolysis primarily involve breaking intra-molecular and intra-particle bonds.•Pyrolytic breaking of pseudo-components in peanut shell follow first-order law.
