1. An adsorber for purifying or separating a gas stream, comprising:
a cylindrical shell,
a domed bottom end,
a domed top end comprising a main filling orifice for a granular material; with said orifice having an inside diameter Din,
a first granular material of grain size ADN,
a second granular material of grain size M, and
a granular-material filling system that is removable from the shell and positioned in the main filling orifice,
wherein,
the granular-material filling system is made up of a cylinder that is perforated over all or part of the height, of the top end thereof of diameter Dext, and of the bottom end thereof,
the distance Din-Dext is greater than twice the grain size of the particles of the second granular material,
the first granular material and the second granular material follow one another in the direction of circulation of the gas stream and are such that M>ADN,
the second material is in contact both with at least a part of the outer surface of the granular-material filling system and at least a part of the inner surface of the domed top end.
