Abstract:
1. A permselective membrane reactor comprising: a cylindrical reactor body having a gas inlet on one end thereof and a retentate gas outlet as a gas outlet thereof at an end thereof opposite to the gas inlet; a separation tube inserted into the center portion of the cylindrical reactor body, wherein the separation tube has an open end as a permeate gas outlet positioned adjacent to the gas outlet of the reactor body, and an opposed round bottom portion positioned adjacent to the gas inlet of the reactor body, and wherein the separation tube has a permselective membrane formed of a Pd membrane or a Pd alloy membrane formed on at least an outer surface thereof; a first catalyst layer disposed in direct contact with the outer surface of the permselective membrane; and a second catalyst layer disposed in direct contact with the first catalyst layer and away from the permselective membrane as compared with the first catalyst layer, wherein the first catalyst layer is a noble metal-based catalyst and the second catalyst layer is an iron-based catalyst.
