The depletion of non-renewable energy sources and the increasing environmental issues have heightened interest in biomass-based renewable energy sources. Biomass is an environmentally friendly and sustainable energy source that can be derived from animals, plants, and microbial waste. This study aims to investigate the pyrolysis processes of lentil stalk biomass and determine its kinetic and thermodynamic properties. The thermal degradation behavior of lentil stalk was evaluated using thermogravimetric analysis (TGA) experiments conducted at different heating rates (3 °C min-1, 5 °C min-1, 7 °C min-1, and 10 °C min-1). The pyrolysis stages of lentil stalk were identified using TG and DTG graphs, and decomposition mechanisms were analyzed. Kinetic calculations were performed using both model-free methods, including Flynn-Wall-Ozawa (FWO) and Kissinger-Akahira-Sunose (KAS), and the model-based Coats-Redfern method. The analysis determined the activation energies for lentil stalk and identified the reaction mechanisms. This study provides valuable scientific data for the development of renewable energy sources by contributing to the evaluation of agricultural waste, such as lentil stalk, for biofuel production.
