Abstract

NiO, Fe2O3, and bimetallic oxide NiFe2O4 catalysts supported on graphene oxide and promoted with ZrO2 were synthesized via wet-impregnation approach. A systematic characterization of the catalysts physicochemical properties was evaluated using X-ray diffraction (XRD), Thermogravimetric analysis (TGA), Fourier Transform Infrared (FTIR), Temperature -programmed desorption CO2 (TPD-CO2), Brunaur-Emmett-Teller (BET) surface area, Field emission Scanning electron microscopy (FESEM), and Transmission electron microscopy (TEM) analysis. Their catalytic performance was employed as a heterogeneous catalyst in the deoxygenation reaction (DO) of palm oil for green diesel production under varying conditions. The Fe2O3/ZrO2-GO catalyst (calcined at 400 oC, for 4 hours, and 5wt% catalyst loading) demonstrated superior activity, achieving a maximum hydrocarbon yield HC% of 98.0 %, bio-jet fuel BJF selectivity of 40 %, and Kerosene yield of 86 %. Furthermore, the catalyst exhibited significant stability and reusability over four consecutive reaction cycles, retaining (92 %) hydrocarbon yield, (80.9 %) kerosene yield, with an increased BJF selectivity to 84%. The decrease in HC yield resulted from carbon deposition, pore blockage, and degradation of the mesoporous network.
