PROBLEM TO BE SOLVED: To provide a dehydrogenation device and a dehydrogenation method capable of efficiently dehydrogenating an organic hydrogenated compound so as to discharge hydrogen while saving energy.SOLUTION: A carrier membrane carried with a catalyst for dehydrogenating a liquid organic hydrogenated compound (dehydrogenation catalyst) is installed in the outer surface of a pipe including a heater, and the liquid organic hydrogenated compound is fed from the upper part of the pipe to the carrier membrane with gravity. As a result, the liquid organic hydrogenated compound is contacted with the dehydrogenation catalyst in a liquid membrane state without using power such as a pump. In this invention, since the heat energy of the produced hydrogen and the dehydrogenated compound is recovered, energy efficiency is also high. The hydrogen is discharged at high purity from a hydrogen discharge port provided with a hydrogen separation membrane. Further, by cooling the dehydrogenated compound and positively condensing the same, the efficiency of the dehydrogenation reaction is high as well.SELECTED DRAWING: Figure 1 【課題】省エネルギーでありながら、効率よく有機水素化合物を脱水素化し、水素を取り出し得る有機水素化化合物の脱水素化装置及び脱水素化方法を提供すること。【解決手段】液体の有機水素化化合物を脱水素化するための触媒（脱水素化触媒）を担持させた担持膜を、ヒータを内蔵したパイプの外表面に設置し、パイプ上部から重力によって液体の有機水素化化合物を担持膜へと供給する。その結果、ポンプのような動力を使用することなく、有機水素化化合物を液膜状態で脱水素化触媒と接触させる。本発明では、生成された水素及び脱水素化化合物の熱エネルギーを回収するために、エネルギー効率も高い。水素は、水素分離膜を設けた水素取出口から高純度で取り出される。さらに、脱水素化化合物を冷却して積極的に凝縮させることにより、脱水素化反応の効率も高い。【選択図】図１
