Catalytic reduction of N2O by various hydrocarbons over Fe-ZSM-5: nature and reactivity of carbonaceous deposits

The SCR of N2O by various hydrocarbons was studied over Fe-ZSM-5. Two types of carbonaceous deposits (Cα and Cβ) were formed on the catalyst. Hydrocarbon reductants were phenomenologically divided into three groups, namely CH4, C3H6, and others (C2H4, C2H6, C3H8), referred to as C2H4 groups.
