Abstract:
The invention provides a method and system for the purification of exhaust gas from an internal combustion engine, comprising a filter and a SCR catalyst. The filter is periodically regenerated increasing the temperature of the exhaust gas up to 850° C. and the water vapor content up to 100% by volume. The SCR catalyst comprises a hydrothermally microporous stable zeolite and/or zeotype having the AEI type framework and being promoted with copper.
