The Treatment of Wasted Gas in GC Hydrogen Isotope Separation(In Chinese)

The ways used to treat wasted gas in GC hydrogen isotope separation were introdused.Catalytic oxydation and cryogenic absorption which can be applied to circle run separation system were introdued emphatically.The result of experiment shows that in catalytic oxydation system without air or oxygen,little hydrogen in helium was deleted,but 99.99%～99.999% helium can be produced when a mass of air was added to the gas flow and that in cryogenic absorption system,98% hydrogen and 99% helium was produced without any additional treatment,such hydrogen can be used in hydrogen-oxygen combination reaction,after next treatment,such helium can be used as transferring gas.
