Abstract
Oxides of nitrogen are adsorbed onto the surfaces of gas passages ( ) in a bed ( ) that has relative rotation with respect to a gas inlet distributor ( ). The manifold has a baffle ( ) or ribs ( ) that causes constantly flowing engine exhaust ( ) to enter the gas passages over a large portion of a revolution of the adsorption bed or the distributor, and causes constantly flowing regeneration gas ( ) to thereafter pass through those passages during a small portion of each revolution. The passages may be formed by planar ( ) or helical ( ) radial walls ( ), a serpentine wall ( ), a monolith ( ), or a honeycomb ( ). Either the distributor ( ) or the bed ( ) may be rotated to distribute the gases.
