Abstract (en)
[origin: WO2011125050A1] A catalyst is provided, preferably for the use in selective catalytic reduction (SCR).Said catalyst comprises one or more zeolites of the MFI structure type, and one or more zeolites of the BEA structure type, wherein at least part of the one or more zeolites of the MFI structure type and at least part of the one or more zeolites of the BEA structure type respectively contain iron (Fe). Furthermore, provided are an exhaust gas treatment system comprising said catalyst as well as a process for the treatment of a gas stream comprising NOX using said catalyst as well.
