چکیده انگلیسی
A series of promoted Pd catalysts supported on a mixed γ-Al2O3–TiO2 support was prepared for use in selective catalytic reduction (SCR) of nitrogen oxides (NOx) using hydrogen rich syngas as a reductant. The catalysts, containing Pd, Fe, Co and K incorporated through incipient wetness, were characterized in terms of surface area, elemental composition and crystalline chemical phase. The NOx reduction (DeNOx) activity of the catalyst series was measured as a function of temperature in a flow reactor system fed with a simulated diesel engine exhaust. The catalyst series shows high NOx conversion and favorable selectivity to N2 over a wide range of temperature compared to results on similar catalyst systems reported to date.
