ABSTRACT:
An exhaust gas treatment system (8) for a diesel engine (10) having a NOx absorber (28) charged with solid absorbent for absorbing NOx from a diesel exhaust gas and means (18) for introducing intermittently into the exhaust system CO upstream of said absorber (28) whereby the solid absorbent is regenerable by contact with the CO-enriched gas. A process for treating NOx in a diesel exhaust gas comprises absorbing the NOx in a solid absorbent and regenerating the absorbent by contacting it with CO-enriched gas.
