  • Process for purification of argon from oxygen
    Patent number: 3996028
    Abstract: A process for purification of argon from oxygen comprises the step of absorption of oxygen by passing argon through synthetic zeolites of the A type with a diameter of the entry voids from 2.8 to 4.2A. Oxygen is adsorbed under a pressure of argon of 21.38-427 p.s.i.a. Then oxygen is desorbed from zeolites by reducing the pressure from 21.38-427 p.s.i.a. to atmospheric pressure with subsequent vacuum treatment of the zeolites at a pressure of 1-10.sup.-.sup.2 mm Hg. The steps of adsorption, desorption and vacuum treatment are carried out under thermostatic treatment of zeolites with a refrigerant so that a temperature of zeolites at the adsorption stage is maintained at -186.degree. C to -133.degree. C.

  • Process for the preparation of synthetic zeolites
    Patent number: 3979335
    Abstract: A process for the preparation of synthetic zeolites comprising mixing zeolite powder of a particle size not exceeding 5 mcm with a natural binder of a particle size of 250-500 A. The resulting mixture is wetted with water and pelletized, the pellets thus obtained being calcined at 600.degree.-700.degree.C.

  • Method of purifying a neon-helium mixture
    Patent number: 3963462
    Abstract: A method of purifying a neon-helium mixture containing 2 to 7 vol.% of neon, 1 to 3 vol.% of helium, 0.5 to 1.5 vol.% of hydrogen, 88.5 to 96.5 vol.% of nitrogen, traces of oxygen and traces of hydrocarbons having from 1 to 5 carbon atoms by freeing said mixture from nitrogen, oxygen, hydrogen and hydrocarbons, which comprises removing nitrogen by dephlegmation at a temperature of from 67.degree. to 77.degree.K. and a pressure of 4 to 7 kgf/sq.cm. to give a mixture containing 68 to 74 vol.% of neon, 22 to 74 vol.% of helium, 1.5 to 2 vol.% of hydrogen, 1 to 8 vol.% of nitrogen and trace amounts of oxygen and hydrocarbons. The latter mixture is passed at a pressure of from 4 to 7 kgf/sq.cm. through microporous adsorbents having 3 to 9-A micropores, adsorbing the remaining nitrogen, oxygen, hydrogen and hydrocarbons. Then said impurities are desorbed by gradually reducing the pressure of the mixture from 4 to 7 kgf/sq.cm. down to 10.sup.-.sup.1 to 10.sup.2 mm Hg.
