A method for the removal of volatile organic compounds, particulate matter and nitrogen oxides from exhaust gas of a compression ignition engine comprising the steps of (a)contacting the exhaust gas with an oxidation catalyst active in oxidation of volatile organic compounds and carbon monoxide to carbon dioxide and water and nitrogen oxide to nitrogen dioxide; (b)introducing a urea solution into the exhaust gas from step(a) and hydrolysing the urea solution to ammonia; (c)introducing the exhaust gas from step (b) into a plurality of inlet channels of a catalyzed wall flow particle filter and filtering off the particulate matter by passing the exhaust gas through gas permeable porous partition walls into a plurality of outlet channels of the wall flow particle filter and depositing the particulate matter on surface of the walls facing the inlet channels; (d) removing the deposited particulate matter by reaction with the nitrogen dioxide contained in the exhaust gas and decreasing remaining amounts of NOx in the exhaust gas by contact with an SCR active catalyst in presence of the ammonia, the SCR active catalyst comprises oxides of vanadium and tungsten arranged within the gas permeable porous partition walls and/or on the plurality of the inlet and/or outlet channels of the wall flow particle filter; the method being characterized in that it further comprises the step of (e) removing remaining amounts of NOx and ammonia slip from step (d) and adsorbing volatile vanadium and tungsten compounds volatilized off the SCR active catalyst in step(d) in a three way catalyst downstream to step (d) having an NH3-SCR activity, an ammonia oxidation activity and an adsorption capacity for volatile vanadium and tungsten compounds volatilized off the SCR active catalyst of the particulate filter (c), the three way catalyst comprising at least one of oxides of vanadium, tungsten and titanium admixed with at least one of a high surface compounds selected from high surface metal oxides, zeolites, silica, non-zeolite silica alumina, and mixtures thereof. (a)contacting the exhaust gas with an oxidation catalyst active in oxidation of volatile organic compounds and carbon monoxide to carbon dioxide and water and nitrogen oxide to nitrogen dioxide; (b)introducing a urea solution into the exhaust gas from step(a) and hydrolysing the urea solution to ammonia; (c)introducing the exhaust gas from step (b) into a plurality of inlet channels of a catalyzed wall flow particle filter and filtering off the particulate matter by passing the exhaust gas through gas permeable porous partition walls into a plurality of outlet channels of the wall flow particle filter and depositing the particulate matter on surface of the walls facing the inlet channels; (d) removing the deposited particulate matter by reaction with the nitrogen dioxide contained in the exhaust gas and decreasing remaining amounts of NOx in the exhaust gas by contact with an SCR active catalyst in presence of the ammonia, the SCR active catalyst comprises oxides of vanadium and tungsten arranged within the gas permeable porous partition walls and/or on the plurality of the inlet and/or outlet channels of the wall flow particle filter; the method being characterized in that it further comprises the step of (e) removing remaining amounts of NOx and ammonia slip from step (d) and adsorbing volatile vanadium and tungsten compounds volatilized off the SCR active catalyst in step(d) in a three way catalyst downstream to step (d) having an NH3-SCR activity, an ammonia oxidation activity and an adsorption capacity for volatile vanadium and tungsten compounds volatilized off the SCR active catalyst of the particulate filter (c), the three way catalyst comprising at least one of oxides of vanadium, tungsten and titanium admixed with at least one of a high surface compounds selected from high surface metal oxides, zeolites, silica, non-zeolite silica alumina, and mixtures thereof.
