NOVELTY - A dehydrogenation device of organic compound is a flow-type reactor having reaction-side area (4) comprising a hydrogen separation membrane (2) and dehydrogenation catalyst (3) capable of promoting the organic compound dehydrogenation reaction, and permeated side area (5) through which hydrogen (EE) permeated through membrane is passed. Reactor has a portion (CC) comprising hydrogen separation membrane and does not comprising dehydrogenation catalyst, and portion (BB) comprising both membrane and catalyst, sequentially provided along the flow direction of the organic compound.    USE - Dehydrogenation device of organic compound for producing hydrogen (claimed).    ADVANTAGE - The dehydrogenation positioning is effectively prevented.    DETAILED DESCRIPTION - A dehydration device of organic compound is a flow-type reactor having a reaction-side area comprising a hydrogen separation membrane capable of selective permeation of hydrogen and a dehydrogenation catalyst enabling release of hydrogen during dehydrogenation reaction and capable of promoting the organic compound dehydrogenation reaction, and a permeated side area which is partitioned by the hydrogen separation membrane from the reaction-side area and through which hydrogen permeated through membrane is passed. The reactor has a secondary portion comprising hydrogen separation membrane and does not comprising dehydrogenation catalyst, and a primary portion comprising both membrane and catalyst, sequentially provided along the flow direction of the organic compound. INDEPENDENT CLAIMS are included for the following:    (1) production of hydrogen, which involves moving hydrogen produced by dehydrogenation of organic compound in reaction side area of portion (BB) to permeation side area, and moving hydrogen to reaction side area of portion (CC) through separation membrane; and    (2) manufacturing apparatus of hydrogen, which has a reaction material container (1), to which organic compound is introduced, flow through-type reactor connected to container and containing dehydrogenation catalyst, a product container connected to reactor, hydrogen container adjacent to both reaction material container and product container, a primary hydrogen separation membrane for separating space in hydrogen container and product container, and secondary hydrogen separation membrane for separating space in hydrogen container and reaction material container.
