英文摘要: Metal-foam-coated 0.09 wt% [Pd(7)-Rh(1)]/(CeZrO2-Al2O3) catalyst was compared with commercially available alumina-supported 8.0 wt% Ru and 13.0 wt% Ni catalysts for steam reforming of a model biogas. The experiments were conducted in a tubular reactor using a feedstock with the steam-to-methane ratio of 1.50 at 1 atm pressure and 20,000 h-1 GHSV. CH4 reforming reactions by steam alone and by CO2 alone were also studied over these catalysts in order to explain the catalyst activity. The Pd-Rh catalyst is superior in a number of ways, including better activity for CH4 and CO2 conversion in spite of much less ingredient loading per unit volume. The Pd-Rh catalyst also exhibited higher syngas production index [(H2 LHV + CO LHV)/(Feed CH4 LHV)], lower syngas H2/CO ratio and coke formation. The results were supported by BET measurement, CO chemisorption and electron microscopy. The experimental results demonstrate that the metal-foam-coated Pd-Rh/(CeZrO2-Al2O3) catalyst performs better for syngas production through steam-biogas reforming compared to the Ru and Ni catalysts. © 2015 Elsevier Ltd.
