Catalytic co-pyrolysis of ironbark and waste cooking oil using X-strontium /Y-zeolite (X= Ni, Cu, Zn, Ag, and Fe)

Catalytic co-pyrolysis (CCP) of ironbark (IB) and waste cooking oil (WCO) over bimetallic (Ni, Cu, Zn, Ag, and Fe) strontium oxide (SrO)-loaded hierarchical Y-zeolite was performed using Py-GC/MS. The effect of bimetallic catalyst on kinetics, reaction mechanisms and product distribution of CCP was examined. The bimetallic catalysts were prepared via wet impregnation and characterized using N2 adsorption-desorption, SEM, XPS and FTIR. CCP using Ag–SrO/Y-zeolite showed the lowest activation energy of 163.1 kJ/mol compared to non-catalytic co-pyrolysis (193.21 kJ/mol). The results indicated that Cu–SrO/Y-zeolite produced the highest aromatic yield of 65.43% at a temperature of 750 °C with a catalyst to feedstock ratio of 1:1. The present work indicates that Cu–SrO/Y-zeolite active sites increased the aromatic yield.
