A container for carbon molecular-sieve material which is designed to prevent contamination of carbon materials within the container. The container includes a hollow section with a preferably circular internal cross-section and a rectangular or square external cross-section. Attached to each end of the hollow section are screened structures designed to retain the molecular-sieve material within the hollow section. These screened structures are preferably secured in place by clamping rings. The hollow section can be hermetically sealed for transport and can be sealed by cover plates and bolts.

[ We claim:] [1.] A portable container for receiving a carbon molecular sieve material for use in a gas adsorption apparatus, said container comprising a hollow section having two ends and extending substantially longitudinally through said container, a screen positioned at each end of said hollow section to maintain said sieve material in said hollow section, a screen retainer to position said screen at each end of said hollow section, a sealing arrangement at each end of said hollow section adapted to hermetically seal said sieve material in said hollow section and to secure said screen retainer to each end of said hollow section, said sealing arrangement including a gas-tight metal material bolted to each end of said hollow section and an adhesive positioned between said metal material and each end of said hollow section. [12.] A method of producing nitrogen in a pressure alternation adsorption process comprising the steps of:a) hermetically sealing a carbon molecular sieve material in a container, said container including a housing having a hollow section having two ends and extending substantially longitudinally therethrough and designed to hold said carbon molecular sieve material, a screen positioned at each end of said hollow section to maintain said sieve material in said hollow section, a screen retainer to position said screen at each end of said hollow section, a sealing arrangement at each end of said hollow section adapted to hermetically seal said sieve material in said hollow section and to secure said screen retainer to each end of said hollow section, said sealing arrangement including a gas-tight material covering each end of said hollow section and bolted to each end of said hollow-section and an adhesive positioned between said gas-tight material and each end of said hollow section;b) breaking said hermetic seal at least one end of said hollow section;c) mounting said container on a container support to hermetically seal each end of said hollow section to said container support and to secure said screen retainer to each end of said hollow section, said container support including two passageways, said fist passageway being in fluid communication with one end of said hollow section and said second passageway being in fluid communication with said other end of said hollow section; and,d) supplying gas in one end of said hollow section and withdrawing gas from said second end of said hollow section during a pressure adsorption process. A method as defined in claim 12, wherein at least two of said containers are modularly connected to said container support, said gas supply to said two containers is controlled such that when one of said containers is used in the adsorption phase, the other of said container regenerated. The method as defined in claim 12, wherein said container is made of aluminum; said hollow section having a substantially circular cross-sectional area; said screen including a wire mesh, perforated sheeting, sintered metal and combinations thereon; said screen retainer being a clamping ring; and said sealing arrangement adapted to secure said screen and screen retainer to each end of said hollow section. The method as defined in claim 13, wherein said container is made of aluminum; said hollow section having a substantially circular cross-sectional area; said screen including a wire mesh, perforated sheeting, sintered metal and combinations thereof; said screen retainer being a clamping ring; and said sealing arrangement adapted to secure said screen and screen retainer to each end of said hollow section. A method as defined in claim 12, including the step of breaking said hermetic seal at each end of said hollow section. A method as defined in claim 15, including the step of breaking said hermetic seal at each end of said hollow section.
