Ammonia Storage Cartridge With Optimized Filling Time, in Particular for a Motor Vehicle Gas Exhaust system

摘要

An ammonia storage cartridge includes_an ammonia storage member having a storage material capable of absorbing or adsorbing ammonia. The storage member extends along a longitudinal axis. A heating element heats the storage member, and a hermetic tank houses the storage member. A tubular ammonia circulation element is arranged coaxially to the storage member, and includes_a first surface at least partially delimiting, with an element chosen from among the heating element and the hermetic tank, a circulation duct for the fluid ammonia. A second surface is arranged at least partially in contact with the storage member, and—at least one orifice passes radially through, allowing the circulation of fluid between the circulation duct and the storage member.

1. An ammonia storage cartridge, in particular for a motor vehicle gas exhaust system, comprising:
an ammonia storage member, comprising a storage material capable of absorbing or adsorbing ammonia, the ammonia storage member extending along a longitudinal axis; a heating element designed to heat the ammonia storage member; and a hermetic tank in which the ammonia storage member is housed, wherein the ammonia storage member includes a tubular element for ammonia circulation in fluid form, the tubular element arranged coaxially to the ammonia storage member 7 such that the tubular element includes: a first surface at least partially delimiting, with an element chosen from among the heating element and the hermetic tank, a circulation duct for fluid ammonia, a second surface, arranged at least partially in contact with the ammonia storage member, and at least one orifice passing radially through, allowing the circulation of fluid between the circulation duct and the ammonia storage member.
