Abstract: Exhaust gas is conducted via a selective catalytic reduction (SCR) catalytic converter (3) for the reduction of nitrogen oxides to form nitrogen, via an oxidation catalytic converter (4) for the oxidation of carbon monoxide and hydrocarbons to form carbon dioxide, and through a diesel particle filter (5) for the removal of particles. Urea solution, or a solution of some other water-soluble compound which releases ammonia, is used as a reducing agent. The reducing agent is dosed into the exhaust section upstream of the charging turbine (1). Exhaust gas generated by a diesel engine with a charging turbine and which, in addition to carbon monoxide, hydrocarbons, and particles, contain nitrogen oxides with a nitrogen-dioxide/nitrogen oxide ratio of 0.3-0.7, is conducted via a selective catalytic reduction (SCR) catalytic converter for the reduction of nitrogen oxides to form nitrogen, via an oxidation catalytic converter for the oxidation of carbon monoxide and hydrocarbons to form carbon dioxide, and through a diesel particle filter for the removal of particles. Urea solution, or a solution of some other water-soluble compound which releases ammonia, is used as a reducing agent for the SCR reaction. The reducing agent is dosed into the exhaust section upstream of the charging turbine. An independent claim is included for exhaust-gas purification device.

Abstract: The method comprises the following steps: conduction of the gas containing N2O and NOx over a series of two catalyst beds consisting of one or more zeolites charged with iron; addition of a reduction agent for NOx between the catalyst beds; setting of a temperature of less than 500 °C in the first and second catalyst bed; setting of a gas pressure of at least 2 bar in the two catalyst beds; and the selection of a space velocity in the first and second catalyst bed that achieves a degradation of the N2O content of the gas in the first catalyst bed by a maximum of up to 90 %, in relation to the N2O content at the entrance to the catalyst bed and an additional degradation of the N2O content of the gas in the second catalyst bed by at least 30 % in relation to the N2O content at the entrance to the second catalyst bed. The first reaction zone is used to degrade the N2O and the second reaction zone reduces the NOx and breaks down at least part of the remaining N2O. The inventive device comprises at least one radially traversed catalyst bed.
