Synthesis of Ru-based catalysts for CO2 methanation and experimental assessment of intraporous transport limitations
Aiming at the optimization of the efficiency of the CO2 methanation process at industrially relevant conditions on Ru/Al2O3 catalysts, the effect of the size of the catalytic pellet on the catalyst performance has been investigated. For this purpose, γ-Al2O3 spheres of various diameters (100, 800 and 2300 μm) have been impregnated so to achieve a 0.5 wt. % Ru loading. Interestingly, the dry impregnation method has led to the preparation of eggshell catalysts on supports bigger than 100 μm. This indicates a strong interaction between the γ-Al2O3 support and the Ru precursor, which is thus depos... Mehr ...
