Reaction apparatus and reactor

A reactor comprising:

• a cylindrical reaction vessel including an intermediate part between a supply unit and a delivery part;
• a temperature control unit configured to control a temperature of the intermediate part;
• the supply unit configured to supply a substance to be treated to the reaction vessel and the delivery part configured to deliver a product from the reaction vessel;
• a conveyance mechanism configured to convey the substance to be treated from a side of the reaction vessel close to the supply unit to a side of the reaction vessel close to the delivery part through the intermediate part;
• a fourth support part configured to support one end side of the reaction vessel in a rotatable manner and in such a way that the one end side of the reaction vessel is immovable in an axial direction of the reaction vessel;
• a fifth support part configured to support another end side of the reaction vessel in a rotatable manner and in a state in which the other end side of the reaction vessel is movable in the axial direction of the reaction vessel;
• and
• a reaction vessel drive apparatus that is provided on one end side of the reaction vessel and to which the one end side of the reaction vessel is coupled.
