In this process and apparatus, it is intended to utilise not only the advantages of, on the one hand, the known cooling inside the bed but also, on the other hand, the cooling in the zone following the catalyst bed by carrying out inner cooling in a plurality of catalyst beds connected in series (1,4,9), after cooling of the reaction gas in the zone following the first catalyst bed (2) inside at least one subsequent catalyst bed (9). <IMAGE> |
