METHANATION OF CARBON DIOXIDE AND CARBON MONOXIDE ON SUPPORTED Ni–La2O3–Ru CATALYST

Abstract

Abstract A novel type composite catalyst in which small amounts of La2O3 and Ru are incorporated with Ni substrate supported on a granulated silica having bimodal pore structure, was found to be a very efficient hydrogenation catalyst for selective methane formation from carbon oxides. Contrary to the case of Ni, the rate of CO2methanation on the presented catalyst was greater than that of CO methanation.
