Abstract
An apparatus for recycling exhaust gas includes a vessel containing a reversible ammonia sorber material which is exothermic when sorbing ('loading') ammonia and which is endothermic when releasing ('unloading') ammonia. A first valve selectively couples a source of exhaust gas including ammonia to a first port of the vessel, a second valve selectively couples a vacuum pump to the vessel, and a third valve selectively coupling a second port of the vessel to an output. A controller opens and closes the first valve, the second valve and the third valve to implement a loading phase, an intermediate venting phase and an unloading phase for the vessel.
