Abstract: FLUIDIZED BED METHOD AND REACTOR FOR CARRYING OUT EXOTHERMIC CHEMICAL EQUILIBRIUM REACTIONSAbstractThe invention relates to a process for carrying out exothermic chemical equilib rium reactions in a fluidized-bed reactor, wherein there is a temperature distribu tion in the fluidized bed of the fluidized-bed reactor and the temperature differencebetween the lowest temperature and the highest temperature is at least 10 K. The invention further relates to a fluidized-bed reactor for carrying out chemical reac tions In a fluidized bed (5), wherein at least one heat exchanger (12, 28) is located in the fluidized bed (5) to control the temperature distribution.(Figure 1)
