A reactor of the selective-permeation membrane type (100) which comprises: a reaction tube (1) having an inner space (24) for which a feed opening (22) serving as an inlet for a feed gas (11) and a discharge opening (23) serving as an outlet for an unseparated gas (12) have been disposed; and a separation tube (4) inserted in the inner space (24) of the reaction tube (1). The separation tube (4) has, in the surface exposed to the inner space (24) of the reaction tube (1), a selective-permeation membrane (5) having selective permeability to a specific ingredient and further has a treatment opening (25) which is an outlet for a separated gas (13) which has passed through the selective-permeation membrane (5). The reaction tube (1) has a catalyst for accelerating a chemical reaction, the catalyst being disposed in those parts of the inner space (24) which exclude the separation tube (4). This reactor of the selective-permeation membrane type (100) is characterized in that the catalyst has been disposed as a foam molding comprising a foam (7) having a porous structure and the catalyst fixed thereon. Thus, not only the selective-permeation membrane is inhibited from physically or chemically deteriorating but a gas mixture produced by the catalytic reaction can be efficiently separated with the selective-permeation membrane and drawn out. |
