| Popis: | Ni(7.5 wt.%)/CeO2 and Ni(7.5 wt.%)-Rh(0.5 wt.%)/CeO2 powders (previously prepared by solution combustion synthesis) were washcoated on cordierite monolith and alumina open-cell foam by means of support dip-coating into acid-free catalyst dispersion. Catalytic performances toward the steam reforming (SR) and the oxy-steam reforming (OSR) of biogas were investigated and compared at different temperatures (700–800 ◦C) and weight space velocities (WSV = 70,000–350,000 Nml gcat −1 h−1). Coating load was controlled by multiple depositions; homogeneous and well adherent layers were found. Catalytic tests demonstrated superior performances of the bimetallic samples (Ni–Rh/CeO2) compared to the monometallic one (Ni/CeO2), especially at high space velocity. At the same time, foam showed better performances with respect to the monolithic support toward the SR and OSR processes. |
