Developed countries are increasing their demand for natural gas as it is an industrial requirement for fuel transportation. Most of modern society relies heavily on vehicles. However, the presence of CO₂ gas has led to the categorization of sour natural gas which reduces the quality and price of natural gas. Therefore, the catalytic methanation technique was applied to convert carbon dioxide (CO₂) to methane (CH₄) gas and reduce the emissions of CO₂ within the environment. In this study, samarium oxide supported on alumina doped with ruthenium and manganese was synthesized via wet impregnation. X-ray diffraction (XRD) analysis revealed samarium oxide, Sm₂O₃ and manganese oxide, MnO₂ as an active species. The reduction temperature for active species was at a low reaction temperature, 268.2℃ with medium basicity site as in Temperature Programme Reduction (TPR) and Temperature Programme Desorption (TPD) analyses. Field Emission Scanning Electron Microscopy (FESEM) analysis showed an agglomeration of particle size. The characterised potential catalyst of Ru/Mn/Sm (5:35:60)/Al₂O₃ (RMS 5:35:60) calcined at 1,000℃ revealed 100% conversion of CO₂ with 68.87% CH₄ formation at the reaction temperature of 400℃. These results were verified by artificial neural network (ANN) with validation R² of 0.99 indicating all modelling data are acceptable.
