Modeling and experimental analysis of CO₂ methanation reaction using Ni/CeO₂ monolithic catalyst.

ABSTRACT: In this study, the effect of the cell density of monolithic catalysts was investigated and further mathematically modeled on cordierite supports used in CO₂ methanation. Commercial cordierite monoliths with 200, 400, and 500 cpsi cell densities were coated by immersion into an ethanolic suspension of Ni/CeO₂ active phase. SEM-EDS analysis confirmed that, owing to the low porosity of cordierite (surface area < 1 m² g^-1), the Ni/CeO₂ diffusion into the walls was limited, especially in the case of low and intermediate cell density monoliths; thus, active phase was predominantly loaded onto the channels' external surface. Nevertheless, despite the larger exposed surface area in the monolith with high cell density, which would allow for bet
