VAPOR PHASE REACTION METHOD AND VAPOR PHASE REACTION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a method for restraining temporal deterioration in both of a heat removal tube and a fluidized-bed reactor, the deterioration being caused by long-term use thereof, in a method for performing a vapor phase exothermic reaction by using the fluidized-bed reactor.

SOLUTION: A vapor phase reaction method is provided in which the vapor phase exothermic reaction is performed by feeding reactive raw materials to the fluidized-bed reactor having a plurality of heat removal tubes therein, and the method comprises the steps of: introducing a coolant into the plurality of heat removal tubes arranged in the centralized direction of the fluidized-bed reactor to remove the heat in the fluidized-bed reactor; and discharging the used coolant radially from the fluidized-bed reactor.
