Abstract: 

In this work, the Me/CeO2 (Me = Rh, Ni) catalytic phase was in-situ deposited by the Solution Combustion Synthesis (SCS) on commercial cordierite monolith (500 cpsi) and alumina open-cell foams (20,30,40 ppi). All the coated structures were characterized by SEM/EDX to analyze the morphological characteristics of the coated films; the mechanical stability was analyzed by ultrasound tests; pressure drops at different superficial velocities were derived. The catalytic activity and stability were investigated towards Steam Reforming (SR) and Oxy-Steam Reforming (OSR) of different fuels (CH4, biogas, n-dodecane) and CO2 methanation reaction. High catalytic activity was observed for both reforming and methanation processes, following the order 500 cpsi-monolith < 20 ppi-foam < 30 ppi-foam ≈ 40 ppi-foam. Excellent long-term stability was observed over 200 h of time-on-stream (TOS)
