AbstractThe methanation of CO and CO2 present in coke oven gas was performed in a fixed-bed catalytic reactor at a reaction temperature between 200 and 400 C. Different support materials, including SiO2, Al2O3, ZrO2, and CeO2, were doped with a different percentage of active metals using a standard impregnation and coprecipitation method. The catalysts were characterized using Brunauer-Emmett-Teller analysis, scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and temperature-programmed desorption techniques. The activity of all samples was tested in terms of the percentage of CO and CO2 conversion and CH, selectivity. The results were analyzed on the basis of the difference in the catalytic performance at different active metal loadings and support materials. The effect of the catalytic support on the reducibility, morphology, and active metal dispersion was investigated. The ZrO2-CeO2-supported catalyst prepared under coprecipitation can attain 100% CO conversion at around 300 C and >= 95% CO2 conversion at 400 C and has a CH, selectivity of 99%.
