Biomass pyrolysis is a promising technology for renewable energy production, offering a sustainable alternative to fossil fuels. This process involves the thermal decomposition of organic materials in the absence of oxygen, resulting in the generation of bio-oil, syngas, and biochar. Kinetic modeling of biomass pyrolysis is essential for optimizing the process and enhancing the yield and quality of the products. This abstract presents a comprehensive review of kinetic models used to describe the pyrolysis of various biomass types. It highlights the mechanisms and reaction pathways, including both primary and secondary reactions, that govern the pyrolysis process. The study discusses different modeling approaches, such as the single-step global model, multi-step mechanisms, and more sophisticated models like the distributed activation energy model (DAEM). The impact of key parameters, including temperature, heating rate, and biomass composition, on the pyrolysis kinetics is examined. Additionally, the integration of experimental data with kinetic models to improve the accuracy of predictions is addressed. This review aims to provide insights into the current state of kinetic modeling in biomass pyrolysis and identifies areas for future research to enhance the efficiency and scalability of this renewable energy technology. Biomass pyrolysis is a thermochemical process where organic material is decomposed at high temperatures in the absence of oxygen to produce bio-oil, syngas, and biochar. This process is gaining significant attention for renewable energy production due to its potential to convert a wide range of biomass feedstocks into valuable energy products. The study of kinetic modeling in biomass pyrolysis is crucial as it helps in understanding the reaction mechanisms, optimizing process conditions, and designing efficient reactors.
