Pahuhopu: ʻO ke kānana Molecular Carbon kahi adsorbent hou i hoʻomohala ʻia i nā makahiki 1970, he mea kalapona non-polar maikaʻi loa, ʻo Carbon Molecular Sieves (CMS) i hoʻohana ʻia e hoʻokaʻawale i ka nitrogen hoʻonui ea, me ka hoʻohana ʻana i ke kaʻina hana nitrogen haʻahaʻa haʻahaʻa i ka mahana o ka lumi, ma mua o ke kaʻina hana nitrogen kiʻekiʻe hohonu hohonu kuʻuna he emi nā kumukūʻai hoʻopukapuka kālā, ʻo ka wikiwiki hana nitrogen kiʻekiʻe a me ke kumukūʻai nitrogen haʻahaʻa. No laila, ʻo ia ka makemake o ka ʻoihana ʻenekinia i ka hoʻokaʻawale ʻana i ka ea me ka adsorption swing adsorption (PSA) ea, hoʻohana nui ʻia kēia nitrogen i ka ʻoihana kemika, ka ʻoihana aila a me ke kinoea, ka ʻoihana uila, ka ʻoihana meaʻai, ka ʻoihana lanahu, ka ʻoihana lāʻau lapaʻau, ka ʻoihana kaula, ka mālama wela metala, ka lawe ʻana a me ka mālama ʻana a me nā ʻano ʻē aʻe.

Kumu hana: ʻO ke kānana molekala kalapona ka hoʻohana ʻana i nā ʻano kānana e hoʻokō ai i ka hoʻokaʻawale ʻana o ka oxygen a me ka naikokene. I ka adsorption sieve molekala o ke kinoea haumia, nui a me ka mesoporous e pāʻani wale i ke kuleana o ke kahawai, e lawe ʻia nā molekala adsorbed i nā micropores a me nā submicropores, ʻo micropores a me nā submicropores ka nui maoli o ka adsorption. E like me ka mea i hōʻike ʻia ma ke kiʻi ma mua, aia i loko o ka kānana molekala kalapona kahi nui o nā micropores, e ʻae ana i nā molekala me ka nui kinetic liʻiliʻi e hoʻolaha koke i loko o nā pores, me ka kaupalena ʻana i ke komo ʻana o nā molekala diameter nui. Ma muli o ka ʻokoʻa o ka wikiwiki o ka diffusion pili o nā molekala kinoea o nā nui like ʻole, hiki ke hoʻokaʻawale pono ʻia nā ʻāpana o ka hui kinoea. No laila, ʻo ka hoʻolaha ʻana o nā micropores i loko o ka kānana molekala kalapona e pono mai 0.28 nm a i 0.38nm e like me ka nui o ka molekala. I loko o ka pae nui micropore, hiki i ka oxygen ke hoʻolaha koke i loko o ka pore ma o ka orifice pore, akā paʻakikī ka naikokene e hele ma o ka orifice pore, i mea e hoʻokō ai i ka hoʻokaʻawale ʻana o ka oxygen a me ka naikokene. ʻO ka nui o ka pore micropore ke kumu o ka hoʻokaʻawale ʻana o ka oxygen a me ka nitrogen ma o ka kānana molekala kalapona, inā nui loa ka nui o ka pore, maʻalahi ke komo ʻana o ka oxygen a me ka nitrogen i loko o ka micropore sieve molekala, ʻaʻole hiki ke hoʻokaʻawale; inā liʻiliʻi loa ka nui o ka pore, ʻaʻole hiki i ka oxygen a me ka nitrogen ke komo i loko o ka micropore, ʻaʻole hiki ke hoʻokaʻawale.

ʻO ka mīkini hoʻokaʻawale ea nikolika kānana molekala kalapona: ʻike nui ʻia ka mīkini ʻo ia ka mīkini nikolika. ʻO ke kaʻina hana ʻenehana he ʻano adsorption swing pressure (PSA method no ka pōkole) ma ka mahana maʻamau. ʻO ka adsorption swing pressure kahi hana o ka adsorption a me ka hoʻokaʻawale ʻana me ke kumu wela ʻole. Hoʻopili ʻia ka hiki ke adsorption o ka kānana molekala kalapona i nā ʻāpana adsorbed (ʻo ia hoʻi nā molekala oxygen) i ka wā o ke kaomi ʻana a me ka hana kinoea ma muli o ke kumumanaʻo i luna, a me ka desorption i ka wā o ka depressurization a me ka hoʻopau ʻana, i mea e hana hou ai i ka kānana molekala kalapona. I ka manawa like, hele ka nitrogen i hoʻonui ʻia i loko o ka pae kinoea moena ma o ka moena e lilo i kinoea huahana, a ʻo kēlā me kēia ʻanuʻu he hana cyclic. ʻO ka hana cyclic o ke kaʻina hana PSA e pili ana i: ka hoʻouka ʻana i ke kaomi a me ka hana kinoea; Kaomi like; Step-down, hoʻopau; A laila kaomi, hana kinoea; He mau pae hana, e hana ana i kahi kaʻina hana cyclic. Wahi a nā ʻano hana hou like ʻole o ke kaʻina hana, hiki ke hoʻokaʻawale ʻia i ke kaʻina hana hou vacuum a me ke kaʻina hana hou lewa. Hiki i nā lako mīkini hana naikokene PSA ke komo pū me ka ʻōnaehana hoʻomaʻemaʻe compression air, ka ʻōnaehana adsorption swing pressure, ka ʻōnaehana hoʻomalu papahana valve (pono nō hoʻi ka vacuum regeneration i kahi pamu vacuum), a me ka ʻōnaehana hoʻolako naikokene e like me nā pono o nā mea hoʻohana.
