APPARAT TIL GENNEMFOERELSE AF EXOTHERME, KATALYTISKE GASREAKTIONER TIL AMMONIAK- ELLER METHANOLSYNTESE

摘要

The invention relates to a device for performing exothermic catalytic gas reactions for synthesis of ammonia or methanol, comprising essentially a high-pressure shell, an insert, and an upper cover, the insert being equipped at least with two superimposed annular cylindrical catalyst containments 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.
