Claims18
A reducing agent composition to be added to the catalytic reduction process of nitrogen oxides from the exhaust gases, characterised in that the reducing agent composition comprises 20-40% of urea calculated on the weight of the composition, 20-40% of ammonium formate calculated on the weight of the composition, and water.
A method for the selective catalytic reduction of nitrogen oxides in an exhaust gas, comprising supplying to an selective catalytic reduction catalyst in an exhaust gas line a reducing agent composition comprising 20-40% of urea calculated on the weight of the composition, 20-40% of ammonium formate calculated on the weight of the composition, and water.
