<p>PROBLEM TO BE SOLVED: To prevent a reaction product from adhering to the inner surface of the sidewall of a fluid bed reactor.SOLUTION: A fluid bed reaction system 100 includes: a fluid bed reactor 110, a gas introduction part 130 for introducing a fluidizing gas from a gas introduction port 116a disposed at the bottom 112c of the fluid bed reactor so as to form a fluid bed of fluid medium in the fluid bed reactor; a heating part 140 for heating the fluid medium from outside of a sidewall 112b of the fluid bed reactor; and a control part for controlling the gas introduction part such that the fluidizing gas introduced in the fluid bed reactor has a greater flow velocity on the sidewall side than on the center side of the fluid bed reactor. The control part controls the gas introduction part such that the fluidizing gas introduced on the center side of the fluid bed reactor has a flow velocity equal to or greater than the minimum fluidization velocity Umf, and the fluidizing gas introduced on the sidewall side of fluid bed reactor has a flow velocity smaller than the terminal velocity Ut.</p> |
