Abstract
Support assembly for catalyst in a reactor comprises two support bodies with different coeffts. of thermal expansion arranged on opposite sides in such a way as to delimit a catalyst chamber with the same thermal expansion as the catalyst. Specif. one of the support bodies is the reactor wall.
