Water-Gas Shift Reaction over the Carbon-Based Magnetite Catalysts Doped with Ruthenium or Palladium

摘要

The catalytic reaction of carbon monoxide with steam-water-gas shift reaction(WGSR),is a source of hydrogen for the refinery and petrochemical industries,for the nitrogen fertilisers production and for the fuel-cell applications.Typically,the magnetite catalysts obtained by the precipitation method are used in the large-scale WGSR units [1,2].However,our studies have shown [3-5] that the magnetite crystallites deposited on thermally modified carbon are also very active in the water-gas shift reaction,particularly when promoted with chromium [4].
