摘要：This study investigated the pyrolysis behavior and kinetics of lotus leaf biomass using a multi-analytical approach. The physicochemical properties and thermal degradation process were characterized by X-ray diffraction (XRD), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and TG-FTIR spectroscopy. Kinetic analysis via model-free methods, namely Flynn-Wall-Ozawa and Kissinger-Akahira-Sunose, yielded highly consistent apparent activation energies of 145.09 and 146.02 kJ mol-1, respectively. The thermal decomposition occurred in two distinct stages: low-temperature dehydration and depolymerization of hemicellulose/pectin, followed by high-temperature pyrolysis of cellulose. TG-FTIR analysis identified water vapor, methane, carbon dioxide, and ammonia as the primary volatile products. The fundamental thermal data and kinetic parameters obtained in this work provide important insights for evaluating the potential of lotus leaf as a feedstock in bioenergy conversion.
