| 제목 | Studies on Steam CO2 Reforming of Methane over High surface perovskite catalysts for GTL-FPSO application |
| 초록 | Steam CO2 reforming of methane (SCR) is a promising way to produce synthesis gas which can be a feedstock for GTL-FPSO process. Perovskite(LaFeO3) support with high surface area were prepared by modified hard template EDTA method and Ni was impregnated on the perovskite. 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 the optimum experimental conditions for SCR of methane. The simulation results were compared with the experimental results under the tested conditions. It was found that the perovskite was prepared by modified hard template EDTA method showed higher catalytic stability and less sintering then that of prepared by pechini method in the SCR of CH4 at the reaction conditions of 850C, 21 bar and molar ratio of CH4:C2O:H2O = 1 : 0.7 : 1.55. It was found that higher surface area led to well dispersion of Ni particles and it enhanced the catalytic performance. |
