ABSTRACT:
A ceramic catalytic membrane reactor for the separation of hydrogen and/or isotopes thereof from fluid, in particular gaseous flows, formed of a tubular support (1) made of a porous ceramic material, which is coated with layers (4) of a gas-tight material at both ends thereof, and with a thin layer or film (2) of a metal or metal alloy having catalytic activity and selective permeability to hydrogen and isotopes thereof, such as Pd or Pd/Ag, on a central portion thereof, where the reaction takes place. The central portion is provided with heating. The seals (6) of the membrane reactor are located on the two gas-tight ends of the tubular support (1).
