Abstract

In the converter having a process gas inlet and outlet, at least one heat exchanger and at least one catalyst bed as well as a further gas feed and having a central pipe and a process gas feed to the heat exchanger and/or catalyst bed, the heat exchanger and the first catalyst bed around the latter being arranged rotationally symmetrically to the central pipe, control gas, quench gas, a part of the process gas at a different temperature and/or under other conditions at a point of a reactor is to be added to the particular gas streams in such a way that the mixing-in and/or the by-pass line are designed for complete isolation, partial loading and/or complete opening. For this purpose, the central pipe (14) for temperature control as a control gas feedpipe completely penetrates the heat exchanger (4 and/or 5 and/or 6) and is provided at its lower end with controllable outlets (18) for at least partial mixing of the control gas with the process gas stream, before the latter flows through the catalyst bed (4), and/or for mixing the control gas stream with the process gas stream after the latter has passed through the catalyst bed (4) and the heat exchanger (7). <IMAGE>
