The aim of this work was to study the thermal degradation of grass (Cymbopogon schoenanthus) under an inert environment at three heating rates, including 10, 30, and 50 degrees C min (1) in order to evaluate its bioenergy potential. Pyrolysis experiments were performed in a simultaneous Thermogravimetry-Differential Scanning Calorimetry analyzer. Thermal data were used to analyze kinetic parameters through isoconversional models of Flynn-Wall-Ozawa (FWO) and Kissenger-Akahira-Sunose (KSA) methods. The preexponential factors values have shown the reaction to follow first order kinetics. Activation energy values were shown to be 84-193 and 96-192 kJ mol (1) as calculated by KSA and FWO methods, respectively. Differences between activation energy and enthalpy of reaction values (similar to 5 to 6 kJ mol (1)) showed product formation is favorable. The Gibb's free energy (173-177 kJ mol (1)) and High Heating Value (15.00 MJ kg (1)) have shown the considerable bioenergy potential of this low-cost biomass. (C) 2016 Elsevier Ltd.
