A selective oxidation reaction apparatus, comprising a selective oxidation reactor (6) having a plurality of reactor bodies (31) and (32) formed in double cylindrical shapes partly cut out in the peripheral direction and partitioned by a partition wall (33), the reactor bodies (31) and (32) furth er comprising chambers (36) and (39) partitioned by upper and lower porous plat es (34), (35), (37), and (38) allowing modification gas mixed with oxidation ai r to pass therethrough and filled with selective oxidation catalysts, wherein a gas mixing tube (49) having modification gas inlet holes (49a), allowing the modification gas from the chamber (36) to flow therein, drilled in the outer periphery thereof, allowing the oxidation air (48) to lead from the tip side therein to mix with the modification gas, and capable of feeding the modification gas mixed with the oxidation air (48) into a chamber (51) forme d at the upper part of the chamber (39) of the reactor body (32) is installed in a chamber (47) formed at the upper part of the chamber (36). As a result, th e selective oxidation reactor can be reduced in size to compactly store in a small cylindrical space. |
