  • 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.
