Fluidized bed process and reactor for carrying out exothermic chemical equilibrium reactions

The invention relates to a process for carrying out exothermic chemical equilibrium reactions in a fluidized bed reactor, wherein the fluidized bed of the fluidized bed reactor there is a temperature distribution and the temperature difference between the lowest and the highest temperature is at least 10 K. Furthermore, the invention relates to a fluidized bed reactor for carrying out chemical reactions in a fluidized bed (5), wherein for controlling the temperature distribution at least one heat exchanger (12, 28) in the fluidized bed (5) is arranged.
