Investigation of pyrolysis kinetics parameters and thermal behavior of thermochemically modified bagasse for bioenergy potential

Abstract Biomass is considering a source of organic carbon, which can replace fossil resources by using pyrolysis process, therefore an efficient biomass thermal modification technology has been target so much research. The objective this work to study the potential energy sugarcane bagasse and thermochemically modified for bioenergy use in heat generation energy. analysis was conducted powder-shaped exposure three samples (SB, AC-1, AC-2) at heating rates (5, 7.5 10 °C min −1 ), it possible identify stages degradation some thermochemical reactions, two iso-conversional models, Kissinger–Akahira–Sunose (KAS) Ozawa–Flynn–Wall (OFW) calculate kinetic parameters, such as activation (E ) pre-exponential factor (A). First step about devolatilization volatile matter, moisture, other substances. Degradation hemicellulose, cellulose lignin were shown second step. Characterization analyzes, SEM–EDX textural parameters samples, show presence carbon SB AC-1. Due SEM morphological differences between are showing AC-1 AC-2 present rougher shape with pores, on hand, sample fibrous shape. In conclusion, bagasse, very promising results, future studies, potential.
