METHOD OF PURIFYING GAS MIXTURE FROM HYDROGEN AND/OR ISOTOPES THEREOF Russian patent published in 2015 - IPC B01D53/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of purifying a gas mixture from hydrogen and/or isotopes thereof. A method of purifying a gas mixture from hydrogen and/or isotopes thereof, which includes oxidising hydrogen with oxygen in the presence of a palladium-containing catalyst, according to the invention, includes generating a hydrogen stream through diffusion from the gas mixture through an optimised adsorbent layer which protects the palladium-containing catalyst from components of the gas mixture, wherein the method employs an oxygen-containing peroxide compound of an alkali metal which absorbs water formed on the palladium-containing catalyst and distributed between the adsorbent and the oxygen-containing peroxide compound of an alkali metal; during absorption, oxygen is obtained, which compensates for the loss thereof from the gas mixture during oxidation of hydrogen.

EFFECT: high efficiency of extracting hydrogen from a gaseous mixture in closed volumes owing to optimisation of the diffusion hydrogen stream from the gas mixture and oxidation thereof with oxygen while exposing the formed water to an oxygen-extracting compound and compensating for loss of oxygen during oxidation of hydrogen.
