Abstract: The aim of the present study is to explore the physicochemical characteristics and pyrolysis kinetics of Parthenium Hysterophorus (PH). The physicochemical characteristics such as proximate and ultimate composition, lignocellulosic composition, heating value, and Fourier transform infrared spectroscopy (FTIR) of PH were carried out. Pyrolysis experiments were performed by thermogravimetric analysis under dynamic/non-isothermal conditions at three heating rates of 10°C, 20°C, and 30°C/min. Thermal analysis of PH confirms that the major mass loss occurs in the temperature range of 200°C to 500°C. Model free Flynn-Wall-Ozawa (FWO), Kissinger-Akahira-Sunose (KAS), and Kissinger methods were employed to compute the activation energy using thermogravimetric analysis data. The pre-exponential factors were also determined by Coats-Redfern method. The value of activation energy evaluated by Kissinger method was 135.85 kJ/mol, while the mean activation energy by KAS and FWO methods was 155.75 and 163.17 kJ/mol, respectively. Result showed that the activation energy varies with the degree of conversion. The results of this study suggest that PH has potential to use as a pyrolysis feedstock.
