This research work investigated kinetics, reaction mechanisms and thermodynamic analysis of catalytic co-pyrolysis of ironbark (IB) and waste cooking oil (WCO) mixture using bimetallic catalysts. Catalytic co-pyrolysis (CCP) of IB and WCO over Cu-SrO/Y-zeolite catalyst was performed using Py-GCMS. The bimetallic catalyst was prepared via wet impregnation and characterized by N<sub>2</sub> adsorption-desorption, scanning electron microscope, X-ray diffraction, X-ray photoelectron spectroscopy, and Fourier-transform infrared spectroscopy. The Py-GCMS results indicated that Cu-SrO/Y-zeolite produced the highest aromatic yield of 31.45% at a temperature of 550°C with a catalyst to feedstock ratio of 1:1. A further increase of the CCP temperature to 750°C initiated the formation of alkyl radicals and a hydrocarbon pool to promote the conversion of phenols into poly-aromatics, which increased aromatic yield to 42.4%. Overall, Cu-SrO/Y-zeolite showed the best selectivity toward higher aromatic yield.
