The selective catalytic reduction (SCR) of NO(x) with C3H6 was studied in the presence of oxygen. The double wash-coat monolith catalysts for SCR comprised a lower layer of Au (or Pt)/Al2O3 and a upper layer of zeolites. The catalytic performance of the double wash-coated catalyst was remarkably improved to broaden the temperature window. The Au and Pt particles were dispersed uniformly on the monolith with particle sizes range of 3 approximately 5 nm and 5 approximately 10 nm, respectively. The catalyst binders used were colloidal silica, potassium silicate and tetraethyl orthosilicate, and the best catalyst activity was achieved with using colloidal silica as a binder. The zeolites used for the catalyst upper layer were MCM-41, FER, Y5.3-Zeolite and ZSM5, among which the NH4-ZSM5-coated catalyst showed the highest activity. The experimental results confirmed the promising potential of the double wash-coat, monolith catalyst for SCR of NO(x) with C3H6 due to the effective combination of noble metal monolith catalyst with zeolite for the removal of NO(x) by SCR with hydrocarbons.
