| description | The invention relates to a method for preparing a reducing agent composition, which is used in the selective catalytic reduction of nitrogen oxides and which contains from 20 to 40% by weight of urea, from 20 to 40% by weight of ammonium formate, and water. The composition is prepared by adding urea to the aqueous solution of ammonium formate that is prepared in situ, and by preparing the aqueous solution of ammonium formate using, as starting materials, a source of ammonium, a source of formate, and water. |
