摘要

本研究旨在评估油橄榄种子（OS）的生物能源潜力，并确定有效设计和优化生物能源生产热化学过程所需的热解特性和动力学。为此，采用热重分析（TGA）方法对OS的热解过程进行了广泛的分析。热重分析在氮气（N2）气氛中进行，升温速率为5、10、15和20 K min−1，从室温到1173 K。通过这些分析，评价了OS的分解行为和生物能源潜力。动力学分析采用Flynn-Wall-Ozawa （FWO）、Kissinger-Akahira-Sunose （KAS）、Starink和Tang等转化模型计算活化能、指前因子等动力学参数以及焓（ΔH）、熵（ΔS）、吉布斯自由能（ΔG）等热力学参数。采用Coats-Redfern （CR）法和主样地法确定反应机理。最适合描述热解分解过程的模型是化学动力学模型（F3）。

Pyrolysis of oleaster seed under non-isothermal conditions to assess as bioenergy potential: Kinetic, thermodynamic and master plot analyses

This study aims to evaluate the bioenergy potential of oleaster seed (OS) and to determine the pyrolysis characteristics and kinetics required for the efficient design and optimization of thermochemical processes for bioenergy production. To achieve this, the pyrolysis processes of OS were extensively analyzed using the thermogravimetric analysis (TGA) method. Thermogravimetric analyses were conducted in a nitrogen (N₂) atmosphere at heating rates of 5, 10, 15, and 20 K min⁻¹, from room temperature up to 1173 K. Through these analyses, the decomposition behavior and bioenergy potential of OS were evaluated. For kinetic analysis, various iso-conversion models, including Flynn-Wall-Ozawa (FWO), Kissinger-Akahira-Sunose (KAS), Starink, and Tang, were employed to calculate kinetic parameters such as activation energy and pre-exponential factor, as well as thermodynamic parameters like enthalpy (ΔH), entropy (ΔS), and Gibbs free energy (ΔG). To determine the reaction mechanism, the Coats-Redfern (CR) method and the master plot approach were utilized. The most suitable model to describe the pyrolytic decomposition process is the chemical kinetics model (F₃).

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.
