Method of removing hydrogen and oxygen from gaseous mixtures

Claim 1

A PROCESS FOR THE ALTERNATE REMOVAL OF OXYGEN FROM AN OXYGEN-CONTAINING GAS MIXTURE AND HYDROGEN FROM A HYDROGEN-CONTAINING GAS MIXTURE WHICH COMPRISES THE STEPS OF PROVIDING A BED OF ELEMENT SILVER-CONTAINING CRYSTALLINE ZEOLITIC MOLECULAR SIEVE MATERIAL; CONTACTING AND REACTING SAID OXYGEN CONTAINING GAS MIXTURES WITH SAID BED THEREBY OXIDIZING SAID ELEMENT SILVER AND REMOVING SAID OXYGEN FROM SAID OXYGEN-CONTAINING GAS MIXTURES; DISCHARGING THE RESULTING OXYGEN-DEPLETED GAS FROM SAID BED; CONTAINING THE OXYGEN-CONTAINIG GAS MIXTURES CONTACT AND OXYGEN-DEPLATED GAS DISCHARGE FROM SAID BED UNTIL THE OXYGEN CONCENTRATION IN THE DISCHARGE GAS REACHES A PREDETERMINED VALUE; THEN CONTACTING AND REACTING SAID OXYGEN-LOADED BED WITH SAID HYDROGEN-CONTAINING GAS STREAM AT A TEMPERATURE BELOW ABOUT 150*C. THEREBY REDUCING THE SILVER TO ITS ELEMENT FROM SAID REMOVING SAID HYDROGEN FROM SAID HYDROGEN-CONTAINING GAS MIXTURE;S; DISCHARGING THE RESULTANT HYDROGEN -DEPLETED GAS FROM SAID BED; CONTINUING THE HYDROGEN-DEPLATED GAS MIXTURES CONTACT AND HYDROGEN-DEPLATED GAS DISCHARGE FROM SAID BED UNTIL THE HYDROGEN CONCENTRATION IN THE DISCHARGE GAS REACHES A PREDETERMINED VALUE; AND THEREAFTER CONTACTING AND REACTING ADDITIONAL OXYGEN CONTAINING GAS MIXTURES WITH SAID BED FURTHER OXYGEN REMOVAL THERIN.
