Abstract

A support for ceramic monolith blocks (12) inside a catalytic reactor chamber for cleaning exhaust gas. The blocks (12) are located upon at least one essentially horizontal grating (11) between an inlet to the reactor chamber and an outlet from said chamber. The grating (11) is vertically displaceable between the walls (10) of the chamber. The displaceability is damped by means of resilient means (14). <IMAGE>
