PROBLEM TO BE SOLVED: To provide a reactor which rises reaction efficiency of a methanation reaction more than heretofore by homogenizing reaction temperature in a reaction tube.SOLUTION: A reactor 5 is provided with one or a plurality of reaction tubes 5a in which an input gas X5 is subjected to methanation reaction in the presence of a catalyst 5b. The reaction tubes 5a are adjacently disposed in a shell 5c. One end (upper end) is an inlet port P1 of an input gas X5, and the other end is an outlet port P2 of a gas X6 after methanation. The reaction tube 5a has two inlet ports P3, P4 of the input gas X5 positioned and set at intermediate parts in addition to the one end so as to homogenize a reaction temperature distribution.SELECTED DRAWING: Figure 1 【課題】反応管における反応温度の均一化を図ることによりメタネーション反応の反応効率を従来よりも上昇させる反応装置。【解決手段】入力ガスＸ５を触媒５ｂの存在下でメタネーション反応させる１あるいは複数の反応管５ａを備える反応装置５であって、反応管５ａは、シェル５ｃ内に隣接配置されており、一端（上端）が入力ガスＸ５の流入口Ｐ１であり、他端がメタネーション反応後ガスＸ６の流出口Ｐ２であって、反応管５ａは一端に加えて途中部位に前記入力ガスＸ５の２箇所の流入口Ｐ３，Ｐ４が、反応温度分布が均一になるように位置設定された反応装置。【選択図】図１
