Pyrolysis of Biomass Pineapple Residue and Banana Pseudo-Stem: Kinetics, Mechanism and Valorization of Bio-Char

Pineapple residue and banana pseudo-stem are waste from agricultural production in tropical zones, the characteristics of their pyrolysis should be explored for high-value utilization. Kinetics, thermodynamics, reaction mechanism valorization bio-char during these feedstock were conducted this study. In biomass mainly decomposed at 150–500 °C, there was a significant mass loss peak 650 °C. The activation energy range pineapple pseudo-stem, based on multi-heating rate method, 159–335 169–364 kJ/mol, respectively. Based Gaussian multi-peak fitting derivative thermogravimetric curves deconvoluted with three or four peaks, key components biomass. Interaction between intermediates increased complexity kinetic data. main carbon number organic volatiles C4 C5 residue, C2 C3 pseudo-stem. high content cellulose hemicellulose improved yield volatiles. Porous sourced pseudo-stems had specific capacitance 375 F/g 297 current density 0.5 A/g, This suggested as potential electrochemical materials.
