DEVICE FOR STORING A GAS REDUCING AGENT FOR THE SELECTIVE CATALYTIC REDUCTION OF NITROGEN OXIDES

摘要

The invention relates to a device for storing a gas reducing agent for the selective catalytic reduction of nitrogen oxides, said device comprising at least two cartridges (1, 2) containing a material for storing the reducing agent via adsorption or absorption, which is identical in each cartridge (1, 2). The device is characterized in that all the cartridges (1, 2) have an identical reducing agent storage volume. The invention also relates to an assembly, comprising one such device and a structure (3) for attaching the cartridges, and to a method for supplying reducing agent to a system for selective catalytic reduction of the nitrogen oxides from a combustion engine activating such device.
