Abstract

In a reaction apparatus, a reaction furnace is cylindrical and includes a supply port for receiving a raw material to be supplied at one end and a discharge port for discharging a reaction product at another end. A temperature control region includes an apparatus for controlling a temperature of the reaction furnace. A screw extends from the one end of the reaction furnace to the other end and is configured to be able to convey the raw material toward the discharge port by rotating. A first fluid control region includes a first fluid inlet and outlet for allowing a first fluid to pass through the reaction furnace in a predetermined region in the intermediate part. A second fluid control region includes a second fluid inlet and outlet for allowing a second fluid to pass through a region different from the first fluid control region in the intermediate part.
