Kinetic and thermodynamic parameters of catalytic co-pyrolysis of palm kernel shell (PKS) and high-density polyethylene (HDPE) with three different catalysts (zeolite HZSM-5, limestone (LS) and bifunctional HZSM-5/LS) using thermogravimetric analyser via nitrogen environment were studied. The experiments were carried out at different heating rates ranging from 10 to 100 K/min within temperature range of 50�900 °C. Flynn-Wall-Ozawa (FWO), Kissinger-Akahira-Sunose (KAS) and modified Distributed Activation Energy Model (DAEM) methods were employed in this current study. The average Ea for PKS, HDPE, PKS/HDPE (2:8) � HZSM-5, PKS/HDPE (2:8) � LS, PKS/HDPE (2:8) � HZSM-5/LS, PKS/HDPE (5:5) � HZSM-5/LS, PKS/HDPE (8:2) � HZSM-5/LS are 137.26�145.49, 247.73�250.45, 168.97�172.50, 149.74�152.79, 115.30�120.39, 124.36�129.41, 151.03�154.47 and 152.67�157.31 kJ mol�1, respectively. Among the different catalysts used, LS demonstrated the lowest average Ea (151.30�120.39 kJ mol�1) and �H (109.65�114.74 kJ mol�1). Positive values for �H and �G were found for the catalytic co-pyrolysis of PKS/HDPE mixtures which indicates the process is in endothermic reaction and possess non-spontaneous nature. The kinetic and thermodynamic analyses revealed the potential of PKS and HDPE as a potential feedstock for clean bioenergy production. © 2023 Energy Institute
