Abstract

1. Catalyst carrier body of a large and/or irregularly formed cross-sectional area, consisting of alternating layers of smooth and corrugated sheets, the catalyst carrier body (10 ; 20) being constructed from several smaller units (11 ; 21) which are arranged next to one another in a preselectable cross-sectional area which is bordered by an outer liner (10 ; 20), and the majority of the cross-sectional area being filled out with smaller units (11 ; 21) of circular cross-section, characterized in that the spaces (15 ; 25) present between the units (11 ; 21) where the circular units (11 ; 21) are packed most densely, and/or the spaces (14 ; 24) between the units (11 ; 21) and the outer liner (10 ; 20) are also filled up, at least partially with furthe, yet smaller, units (17 ; 27 or 16 ; 26), whereby remaining free spaces in the original cross-sectional area can be sealed off if desired against the transmission of gas.
