First Claim
Patent Images
1. A method, comprising:
- introducing into a cartridge containing a solid storage media a quantity of gaseous ammonia diluted in a cooled carrier gas to charge the solid storage media with ammonia, wherein the cartridge is used in an exhaust aftertreatment system and the ammonia is released from the cartridge to treat exhaust gas emissions.

7. A method, comprising:
-
introducing into a spent solid storage media contained within a storage media cartridge a quantity of ammonia sufficient to charge the solid storage media with ammonia; and cooling the outside of the storage media cartridge with a cooling system of a vehicle to which the ammonia media cartridge is mounted while introducing the quantity of ammonia. - View Dependent Claims (8, 9, 10)

11. A method, comprising:
-
saturating a spent solid storage media of a storage media cartridge with molecules; and exposing the saturated storage media to a dry gas containing ammonia to displace the adsorbed molecules with ammonia, wherein the heat of desorption of the molecules offsets the heat of adsorption of the ammonia. - View Dependent Claims (12)

13. A method, comprising:
-
storing a compound containing ammonia in a bound form; separating the compound to obtain a stream of ammonia gas; and charging a spent storage media of a cartridge with the stream of ammonia gas to charge the storage media with ammonia, wherein the cartridge is part of an exhaust treatment system, wherein the ammonia gas is separated from the carbon dioxide before charging the spent storage media of the cartridge with the ammonia gas. - View Dependent Claims (14, 15)
