Enhanced NH3 Selective Catalytic Reduction for NOx Abatement

Enhanced NO reduction efficiencies, close to those obtained under the conditions of fast selective catalytic reduction (SCR; see diagram), were achieved over commercial vanadium and iron‐exchanged zeolite SCR catalysts at low temperatures (200–300 °C) in the absence of NO2 by reaction of NO with amm...

Description
Summary:Enhanced NO reduction efficiencies, close to those obtained under the conditions of fast selective catalytic reduction (SCR; see diagram), were achieved over commercial vanadium and iron‐exchanged zeolite SCR catalysts at low temperatures (200–300 °C) in the absence of NO2 by reaction of NO with ammonia and an aqueous solution of ammonium nitrate.
