<P>PROBLEM TO BE SOLVED: To provide a reactor capable of preventing the blocking of a discharge hole 2 for discharging a reaction product and the lowering of a reaction yield or the obstruction of reaction caused by a reaction catalyst peeled from an inner surface 5 of a reactor body 1. Ž<P>SOLUTION: The reactor contains the reactor body which houses a reaction catalyst in its internal space and a wall part protruded from the inner surface facing the internal space of the reactor body and provided in close vicinity to a discharge hole communicating with the inside and outside of the reactor body. The wall part 3 is provided to the periphery of the discharge hole 2 to obstruct the penetration of the reaction catalyst into the discharge hole 2. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
