Hydrogen Production through the Water-Gas Shift Reaction: Thermodynamic Equilibrium versus Experimental Results over Supported Ni Catalysts uri icon

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 H 2 production over nickel-supported catalysts are also evaluated at both low and high temperatures. Ceria-promoted nickel catalyst supported on powder alumina (Ni/CeO 2-A1 2O 3) 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 g cat -1, the activity of Ni/CeO 2-AI 2O 3 was 95% with a H 2 yield of 52% and a H 2 selectivity of 73%. 2009 American Chemical Society.
