PURPOSE: To carry out efficient exothermic reaction by establishing a temp. distribution resulting a lower temp. at the exit of a catalyst layer than a temp. at the inlet of the catalyst layer and recovering major portion of heat of reaction in the form of latent eat of vaporization of cooling liquid.
CONSTITUTION: In a double pipe 4 provided in a cooling liquids shell 8 of a reactor 1, a catalyst layer 6 formed between an internal pipe 2 and an external pipe 3, and the internal pipe 2 is connected to the outside of the reactor for the purpose of introducing raw material fluid 15. The catalyst layer 6 is communicated with the internal pipe 2 so as to flow the fluid having passed the internal pipe 2 toward opposite direction to the direction of flow of the fluid in the internal pipe 2. Simultaneously, an inlet 13 and an outlet 14 of cooling liquid are provided to a cooling liquid shell 8 so as to cause the flow of the cooling liquid parallel to the fluid in the catalyst layer 6. Thus, and neighbourhood of the inlet 10 of the catalyst layer where the reaction temp. is highest is cooled effectively, and major portion of the heat of reaction can be recovered in the form of latent heat of vaporization of the cooling liquid. Efficient exothermic reaction is thus possible.
