ABSTRACT:
Carbonaceous combustion products (i.e., principally carbon dioxide) and water are removed from nitrogen generator gas by molecular sieve adsorption thereof. The molecular sieve material is regenerated by an initial extended purging with ambient air under vacuum followed by a short burst of pure nitrogen under vacuum to remove any entrapped oxygen.
