Abstract
There is disclosed method and systems for charging a depleted or spent solid storage media with gaseous ammonia.
Claims22
A method, comprising:
- introducing into a cartridge containing a solid storage media a quantity of gaseous ammonia diluted in a cooled carrier gas to saturate the solid storage media with ammonia.
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.
A system, comprising:
- an engine with a coolant system and an exhaust system;
- a cartridge with a solid storage media configured to absorb and release a quantity of ammonia, wherein the cartridge is connected with the exhaust system to provide ammonia released from the solid storage media to the exhaust system;
- and
- wherein the coolant system is configured to providing a cooling fluid to cool the solid storage media during charging of the solid storage media with ammonia.

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.
A method, comprising:
- storing a compound containing ammonia in a bound form;
- separating the compound to obtain a stream of ammonia gas;
- and
- saturating 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.
