Abstract:
Device for removing hydrogen from a gas mixture containing free hydrogen and oxygen by means of catalytic oxidation of hydrogen comprising a reaction chamber (6) having a support (1) secured in the reaction chamber, the support having a surface (2) coated with catalytically active materials, serving to dissipate reaction heat, an inlet (7) into the reaction chamber for the gas mixture, an outlet (10) for residual gas that remains after the oxidation of the hydrogen, a liquid bath (3), a part (5) of the catalytically active surface (2) of the support (1) immersed into the liquid bath (3), the temperature of the liquid bath (3) being below the condensation temperature of water vapor formed in the reaction chamber (6), whereby the inlet (7) for the gas mixture to be fed into the reaction chamber (6) concurrently serves as the inlet for the liquid bath (3) and the outlet (10) for the residual gas concurrently serves as the outlet for the liquid bath (3), and whereas both the inlet (7) and the outlet (10) are situated below a liquid level (8) in the reaction chamber (6) whereby the pressure in the reaction chamber is controlled.
