Abstract
This paper discusses the experimental results of the water-gas shift reaction over supported nickel catalysts in comparison to thermodynamic equilibrium composition at the same reaction conditions. The effects of different supports on the performance of H2 production over nickel-supported catalysts are also evaluated at both low and high temperatures. Ceria-promoted nickel catalyst supported on powder alumina (Ni/CeO2-Al2O3) demonstrated excellent performance. The catalyst was not stable at low temperature (250 °C) but showed good stability at high temperature (450 °C). At 450 °C, with a catalyst loading of 0.05 g, CO/S (S = steam)ratio of 1:3, and gas hourly space velocity (GHSV) ≈ 200 L h-1 gcat-1, the activity of Ni/CeO2-Al2O3 was 95% with a H2 yield of 52% and a H2 selectivity of 73%.
