Selective Catalytic Reduction on Filter (SCRoF)

SCR on Filter controls NOx (nitrogen oxides) and PM (particulate matter or soot) emissions from diesel engines, on a single substrate.

This technology combines two components into one:

  • SCR (Selective Catalytic Reduction) which reduces NOx to nitrogen and water in the presence of a reductant, such as AdBlue® by BASF, a high purity urea solution
  • DPF (Diesel Particulate Filter) which filters the PM

The advantages of BASF’s SCR on Filter technology include:

  • BASF’s advanced zeolite SCR technology has superior durability to better withstand active filter regeneration
  • SCRoFperformance similar to SCR and DPF performance on separate components
  • Elimination of a substrate can save space and weight
