Energy Sources , Part A : Recovery , Utilization , and Environmental Effects

In this research, combustion characteristics of lignocellulose biomass (hazelnut shell) and three main components (cellulose, hemicellulose, and lignin) were investigated using thermogravimetry (TGA-DTG) technique at different heating rates. The ignition, peak, burn-out temperatures, and the heat liberation of lignocellulose biomass and three main components were also measured. Two different model-free kinetic methods, known as Ozawa– Flynn–Wall (OFW) and Kissinger–Akahira–Sunose (KAS), were used in order to determine the activation energy values. Throughout the study, it is observed that the activation energy values of the biomass compounds varied between 83.8 and 191.7 kJ/mol for OFW and KAS methods, respectively.
