Two different ratios of catalyst Ru/Fe/M’ (5:30:65)/Al2O3 and Ru/Fe/M’ (5:10:85)/Al2O3 calcined at 1000°C had been prepared at the screening stage. The best catalyst from this stage was further investigated in optimization process at different calcination temperatures of (900ºC - 1100ºC) and based loadings (80 wt% - 90 wt%). In-house-built micro reactor with Fourier Transform Infra Red (FTIR) and TQ analysis software were used to study the percentage of CO2 conversion and also the percentage of CH4 formation. From the catalytic study, Ru/Fe/Sr (5:10:85)/Al2O3 catalyst calcined at 1000ºC was categorized as potential catalyst which gave 90.1% CO2 conversion and 100% selectivity of CH4 at reaction temperature of 300ºC. This catalyst showed polycrystalline structure with the mixture of SrO, Al2O3, Fe2O3 and RuO2 species which was obtained by X-Ray Diffraction (XRD) analysis. The characterization of surface morphology illustrated that the catalyst surface was covered with agglomerated and aggregated particles with staghorn coral shape. Energy Dispersive X-Ray (EDX) analysis confirmed the Sr, Fe, Ru and Al on the catalyst surface. The analysis from Thermogravimetry Analysis (TGA) revealed that 1000°C of calcination temperature was good enough to produce pure metal oxide for the catalyst zulaihi UTM 57 p.
