Abstract
The current study links the heat transport phenomena and reaction kinetics when the pyrolysis was occurring of sugarcane bagasse (SCB) biomass. A thermogravimetric analyzer was used to conduct a kinetic research on the pyrolysis of biomass in a nitrogen atmosphere, covering a heating rate range of 10–40 °C/min. The thermogravimetric studies (TGA) allowed for the differentiation of three stages associated with the breakdown of hemicellulose, cellulose, and lignin. Using three first-order processes and the Arrhenius theory, the activation energy and pre-exponential factor were determined.Three important components of biomass—lignin, hemicellulose, and cellulose—were assumed to respond independently and in parallel in the kinetics model. Additionally, the transport characteristics of each component were assessed using their respective kinetic values and other thermo-physical characteristics. The regulating mechanism was then anticipated by the heat transfer map for three elements with different particle sizes. The transfer qualities were mainly influenced by particle size, at a crucial dimension dictating the shift in the system for several parts.
