Hoej, J. and Beier, M., "Vanadium-Based SCR Systems: Release of Vanadium and Tungsten during Operation and Possibilities for Reducing Vanadium Emissions," SAE Int. J. Engines 7(3):1397-1400, 2014, doi:10.4271/2014-01-1626.
Data on the release of vanadium and tungsten during operation from a vanadium-based Selective Catalytic Reduction catalyst and a newly developed product with advanced thermal stability are presented. The effect of the ammonia slip catalyst as a vanadium trap is highlighted and the implications of the vanadium and tungsten release are briefly discussed.
