Palladium-based Reactor for Membrane-supported Water-gas Shift

Palladium-based Reactor for Membrane-supported Water-gas Shift 

A commercial Cu based catalyst supplied by Haldor-Topsoe was applied to the water-gas shift reaction. At 210 °C, a permeating flux of 4.5 Ndm3 nT2 s 1 was determined for pure hydrogen at a very low pressure drop of 0.2 bar. Then the membrane reactor was coupled with a conventional water-gas shift reactor. At 260-300 °C reaction temperature and a GHSV of 2 085 h 1, the maximum conversion achievable due to the thermodynamic equilibrium could be exceeded by this new technology by 5-10%.
