摘要：
The present invention relates to an integrated system for the treatment of exhaust gases, which consists of at least one NO x -storing component, at least one in situ ammonia-generating component, at least one ammonia-storing component and at least one ammonia (NH 3 )-SCR-component, as well as to a process for the treatment of exhaust gas comprising at least the steps (i) storing of NO x under lean exhaust gas conditions in at least one NO x -storing component; (ii) in situ conversion of the stored NO x to ammonia (NH 3 ) under rich exhaust gas conditions; (iii) storing of the ammonia (NH 3 ) in at least one NH 3 -storing component under rich exhaust gas conditions as well as the (iv) reaction of NH 3 with NO x under lean exhaust gas conditions. Thereby, the partial steps "storing of NO x " and "conversion of NH 3 with NO x " are carried out at least partially and/or temporarily simultaneously and/or parallelly. Furthermore, catalysts for carrying out the process are disclosed.
