| 제목 | Studies on Modified Peorvskite Catalysts over Steam CO2 Reforming of Methane |
| 초록 | Steam CO2 reforming of methane (SCR) is a remarkable way to produce synthesis gas which can be a feedstock for GTL-FPSO process. Modified LaNiO3 based perovskite type catalysts (La1-xMxNi1-yFeyO3, M = Pr, Ce, Sr, Ca) were prepared by modified EDTA-cellulose method. The prepared perovskite type catalysts were characterized by various techniques such as N2 physisorption, CO chemisorption, TPR, XRD, SEM, TEM-EDS and TG analysis. Commercial simulation package was used to estimate optimum experimental conditions for SCR of methane. The simulation results were compared with the experimental results under the tested conditions. It was found that La0.95Ca0.05Ni0.5Fe0.5O3 catalyst shows higher catalytic performance and stability than the other catalysts in the SCR of CH4 at the reaction conditions of 900℃, 21 bar and molar ratio of CH4:CO2:H2O = 1 : 0.7 : 1.63. It was identified that the coke formation was restricted by the addition of alkali metal in reforming catalyst enhance the basicity of the catalysts and it leads strong adsorption of CO2 during SCR reaction. |
