Abstract

Decentralized energy systems in the Amazon face challenges such as diesel dependence, high transport costs, and limited sustainability. Woody residues from sustainable forest management offer a viable bioenergy alternative, yet combustion kinetics, thermodynamics, and emissions data remain scarce. This study provides a comprehensive thermokinetic assessment of four blends comprising six Amazonian wood residues (Peltogyne lecointei, Erisma uncinatum, Martiodendron elatum, Handroanthus incanus, Dipteryx odorata, and Allantoma decandra) for decentralized energy solutions. Combustion kinetics were assessed through thermogravimetric analysis, isoconversional methods (Friedman, Flynn-Wall-Ozawa, Kissinger-Akahira-Sunose, and Starink), and DAEM approaches (Miura-Maki, Scott, and Three-Parallel). Additionally, combustion indexes, thermodynamic parameters, emissions, and carbon uptake were analyzed. Results highlighted differences in ignition and burnout performance, with some blends proving more efficient for energy recovery, while others exhibited prolonged combustion, affecting char formation and thermal stability. Experimental and predicted mass loss profiles strongly agreed (MAPE<6 %), confirming the kinetic approach's reliability. Enthalpy changes ranged from 112.89 to 441.90 kJ mol⁻¹, while Gibbs free energy values of 163.25–248.55 kJ mol⁻¹ confirmed a non-spontaneous process. Entropy variations from −116.31–431.54 J mol⁻¹ K⁻¹ indicated molecular disorder and energy efficiency during biomass decomposition. Emission factors for CO₂ (67.109–69.773 tons MJ⁻¹), SO₂ (0.043–0.056 tons MJ⁻¹), and NOx (0.008–0.011 tons MJ⁻¹) were lower than fossil fuels. CO₂ uptake (1.677–1.776 tons per ton of biomass) further supports carbon mitigation. Findings align with SDG7 (Affordable and Clean Energy) and SDG13 (Climate Action), promoting bioenergy integration into diesel-dependent systems in remote regions.

期刊介绍： Biomass & Bioenergy is an international journal publishing original research papers and short communications, review articles and case studies on biological resources, chemical and biological processes, and biomass products for new renewable sources of energy and materials. The scope of the journal extends to the environmental, management and economic aspects of biomass and bioenergy. Key areas covered by the journal: • Biomass: sources, energy crop production processes, genetic improvements, composition. Please note that research on these biomass subjects must be linked directly to bioenergy generation. • Biological Residues: residues/rests from agricultural production, forestry and plantations (palm, sugar etc), processing industries, and municipal sources (MSW). Papers on the use of biomass residues through innovative processes/technological novelty and/or consideration of feedstock/system sustainability (or unsustainability) are welcomed. However waste treatment processes and pollution control or mitigation which are only tangentially related to bioenergy are not in the scope of the journal, as they are more suited to publications in the environmental arena. Papers that describe conventional waste streams (ie well described in existing literature) that do not empirically address ''new'' added value from the process are not suitable for submission to the journal. • Bioenergy Processes: fermentations, thermochemical conversions, liquid and gaseous fuels, and petrochemical substitutes • Bioenergy Utilization: direct combustion, gasification, electricity production, chemical processes, and by-product remediation • Biomass and the Environment: carbon cycle, the net energy efficiency of bioenergy systems, assessment of sustainability, and biodiversity issues.
