This study focuses on dynamic non-catalytic and catalytic pyrolysis of empty fruit bunch (EFB) with copper oxide doped aluminium oxide (CuO/Al 2 O 3 ) at linear ramp rates of 10, 15, 20, 25, 30 and 40 °Cmin −1 at pyrolysis temperature of 28-1000 °C in a thermogravimetric analyzer (TGA). The thermogravimetric profiles for the thermochemical breakdown of EFB under non-catalytic and catalytic pyrolysis with CuO/Al 2 O 3 comprise of three different levels. The kinetics analysis for the reactions were evaluated using the Kissinger and Ozawa methods. The values of activation energy (Ea) for non-catalytic EFB pyrolysis were 167.95 and 177.68 kJmol −1 based on Kissinger and Ozawa methods respectively. For catalytic pyrolysis with approximately 9.09 wt% CuO/Al 2 O 3 catalyst, the values of Ea reduced to 127.72 and 137.42 kJmol −1 by Kissinger and Ozawa methods respectively. These values indicate that the presence of 9.09 wt% CuO/Al 2 O 3 catalyst has successfully reduced Ea value for the EFB pyrolysis reaction.
