Abstract

In a catalyst support element, esp. for treating exhaust gases from IC engines, comprising felted refractory mineral fibres in the form of a disc with a central zone perforated with axial channels, the peripheral zone of the disc has an av. thermal conductivity lower than that of the central zone. The peripheral zone is pref. perforated by axial channels with an av. density lower than that of the central zone, the av. density of the channels pref. decreasing from the centre to the edge of the disc.
