Abstract
A method for purification of an oxygen contaminated nitrous oxide gas by feeding the nitrous oxide gas and a reducing agent such as hydrogen, carbon monoxide or ammonia into a de-oxidation reactor, performing de-oxidation by reacting the reducing agent with oxygen using a catalyst such as palladium or platinum in order to deplete the oxygen in the nitrous oxide gas, while limiting the amount of nitrous oxide removed from the nitrous oxide gas.
Claims16
A method for purification of a nitrous oxide gas containing O2, said method comprising:
- feeding said nitrous oxide gas and a reducing agent selected from the group consisting of hydrogen, carbon monoxide, ammonia and mixtures thereof into a de-oxidation reactor;
- performing de-oxidation by reacting said reducing agent with O2 using a de-oxidation catalyst selected from the group consisting of palladium, platinum and mixtures thereof to form an inert, in order to deplete said O2 in said nitrous oxide gas, while limiting the amount of nitrous oxide removed from said nitrous oxide gas.
