ABSTRACT The invention relates to apparatus for performing exothermic catalytic gas reactions, for example the synthesis of ammonia or methanol. The apparatus comprises essentially a high-pressure shell, an insert, and an upper cover, the insert being equipped with at least two superimposed annular cylindrical catalyst containers each having a gas-permeable inner and outer wall for radial gas flow from the outside towards the inside and with two tubular gas/gas heat exchangers arranged centrally in the first and second catalyst containers. Reactors of this type are mostly complicated and have poor gas flow conditions. The apparatus of the present invention has the ad- vantage that, via a guide tube and a gas admission chamber, both heat exchangers are interconnected to form a unit. The fixed point of this unit is located near the middle so that the hot part of both heat exchangers is allowed to expand freely.
