PROBLEM TO BE SOLVED: To provide a gas-phase exothermic reaction method for performing a gas-phase exothermic reaction by use of a fluidized bed reactor having heat removal tubes thereinside, which satisfies both minute control of temperature and securing of the safety of the heat removal tubes.SOLUTION: The method for performing a gas-phase exothermic reaction by supplying raw materials to a fluidized bed reactor having a plurality of heat removal tubes thereinside, the heat removal tubes including a heat removal tube for passing water and a heat removal tube for passing steam, includes: adjusting the reaction temperature by controlling the flow rate of the steam so that the ratio of maximum flow rate/minimum flow rate is 3-10. |
