摘要

甘蔗渣被用作能源。在 25 至 900 °C 的温度范围内，以 10、20、30 和 40 °C / 分钟的不同加热速率进行了热重分析。使用 Flynn-Wall-Ozawa (FWO)、Friedman、Kissinger-Akahira-Sunose (KAS) 和 Starink 等等转换模型对动力学和热力学进行了研究，并使用 Coats-Redfern (CR) 模型拟合技术确定了反应机制。应用 Coats-Refern 方法确定了前指数因子。根据 KAS、FOW、Starink 和 Friedman 技术，发现平均活化能（Ea）值分别为 323.46、168.89、162.52 和 174.70 kJ/mol。热力学特征表明，甘蔗渣是一种潜在的原料。热解反应是自发的，能产生足够的能量。这项研究可为甘蔗渣的热化学转化和应用提供理论基础。

Thermo-kinetic analysis of sugarcane bagasse as a sustainable energy resource evaluation

Sugarcane bagasse was used as energy resources. Thermogravimetric analysis was performed at varying heating rates of 10, 20, 30, and 40 °C/min, within the temperature range of 25 to 900 °C. Using the iso-conversional models like Flynn–Wall–Ozawa (FWO), Friedman, Kissinger–Akahira–Sunose (KAS), and Starink, kinetics and thermodynamics were examined, and the Coats–Redfern (CR) model-fitting technique was used to identify the reaction mechanism. The pre-exponential factors were ascertained by applying the Coats–Refern method. According to KAS, FOW, Starink, and Friedman techniques, the average activation energy (Ea) values were found to be 323.46, 168.89, 162.52, and 174.70 kJ/mol, respectively. Thermodynamic characteristics indicate, sugarcane bagasse is a potential feedstock. The pyrolysis reaction was spontaneous, generating sufficient quantity of energy. This research can offer a theoretical foundation for thermochemical conversion of sugarcane bagasse and applications.

期刊介绍： Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
