Selectively permeable membrane reactor

Selectively permeable membrane reactor 100 includes a reaction tube 1 having an inner space 24 and the discharge port 23 and the supply port 22 is the inlet of the raw material gas 11 is an outlet of the unseparated gas 12 is provided, the reaction tube 1 a separation tube 4 inserted into the internal space 24 of the comprises a. Separation tube 4, as well comprises a surface that appears permselective membrane 5 with selective permeability to a particular component in the internal space 24 of the reaction tube 1, which is the outlet of the separation gas 13 that has passed through the selectively permeable membrane 5 treatment comprising a mouth 25, a catalyst for promoting chemical reactions, provided in the inner space 24 of the reaction tube 1 excluding the separation tube 4. The selectively permeable membrane reactor 100, a catalyst is supported on foam 7 having a pore structure, there is characterized in that are arranged as a foam molded body, physical, chemical degradation of the selective permeable membrane It suppresses, and the mixed gas generated by the catalytic reaction permselective membrane at efficiently separate pulling it be.
