Abstract

Biogas conversion to syngas by steam reforming was studied over metal-foam-coated Pd–Rh catalysts with variable CeZrO₂–Al₂O₃ support compositions. Catalysts with a higher CeZrO₂/Al₂O₃ ratio exhibited greater CH₄ and CO₂ conversions and higher H₂/CH₄ yields, while displaying lower H₂/CO ratios and reduced coke formation. Catalytic stability tests over 200 h showed CH₄ and CO₂ conversion rates of 93–97% and 0–5%, respectively. CeZrO₂-modification of the catalyst leads to reduction in the BET area and metal dispersion. Sintering was observed in used catalysts; however there was no clear correlation between the extent of morphological deterioration and the CeZrO₂/Al₂O₃ ratio of the catalyst support.
