Abstract

Disclosed is a catalyst, preferably for use in selective catalytic reduction (SCR), said catalyst comprising 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, an exhaust gas treatment system is described, comprising said catalyst as well as a process for the treatment of a gas stream comprising NOx using said catalyst as well.
