METHOD OF SEPARATION OF GAS IMPURITIES FROM GAS MIXTURES Russian patent published in 2003 - IPC

FIELD: methods of cleaning of gas mixtures. SUBSTANCE: methods includes supply to catalytic reactor of initial gas mixture containing, at least, inert gases; absorption of gas impurities from gas mixtures; withdrawal of cleaned gas mixture from catalytic reactor. Prior to supply of initial gas mixture to internal cavity of catalytic reactor, the latter is filled with mixture of magnesium with active aluminum oxide in preset ratio. Process of absorption accompanied by decomposition and oxidation of impurities components is carried out with continuous heat absorption. Process of absorption of gas impurities may be conducted at temperature of 673-973 K and at absolute pressure of 10 kPa-4 MPa. Initial gas mixture is used in form of xenon-crypton mixture containing gas impurities in form, at least, of hydrocarbons and florine-chlorine derivatives of saturated hydrocarbons. EFFECT: higher efficiency of separation of hydrocarbons and absorption of derivatives of saturated hydrocarbons from crypton-xenon mixtures. 4 cl
