Ua hoʻokō ʻia kahi holomua koʻikoʻi i nā mea adsorbent me ka hoʻonui ʻana o ka Low-Silica X (LSX) zeolite, kahi sieve molekala hanauna hou e mākaukau e hoʻololi i nā kaʻina hana adsorption swing pressure (PSA) no ka hana ʻana o ka oxygen a me nā hoʻokaʻawale kinoea ʻē aʻe.
ʻO nā zeolites kuʻuna, nā aluminosilicates crystalline me nā ʻano pore kikoʻī, he mau lio hana i ka hoʻokaʻawale ʻoihana a me ka hoʻomaʻemaʻe. ʻO ka zeolite NaX (13X) i hoʻohana nui ʻia, me ka lakio silicon-to-aluminum (Si/Al) o 1-1.5, he pae hoʻohālikelike no ka hoʻopili ʻana o ka nitrogen mai ka lewa. Hoʻokuke hou ka zeolite LXS i hoʻomaikaʻi ʻia i kēia palena ma ka hoʻokō ʻana i kahi lakio Si/Al e like me 1.0, e hōʻea ana i ka palena kumumanaʻo o ka ʻōnaehana zeolite X.
Hoʻonui nui kēia ʻano silica haʻahaʻa loa i ka nui o nā cation sodium kaulike-hoʻouka i loko o nā pores. Hoʻokumu kēia mau cation i nā wahi pilina electrostatic ikaika, e hoʻonui nui ana i ka pili o ka mea no nā molekala quadrupolar e like me ka nitrogen (N₂). No laila, hōʻike ʻo LXS i kahi hiki ke hoʻohuihui nitrogen a me ke koho ʻana ma luna o ka oxygen (O₂) i hoʻohālikelike ʻia me kona hoa 13X maʻamau.
"Hōʻike ʻo LXS i kahi holomua ʻepekema mea no ka ʻenehana adsorption," wahi a Kauka [Fictional Name], he alakaʻi noiʻi ma ka Advanced Materials Institute. "Ma ka hoʻonui ʻana i ka ʻike alumini i loko o ke kahua FAU, ua hana mākou i kahi kānana me ka nui o nā wahi hana. Hoʻololi pololei kēia i ka hana oxygen ʻoi aku ka maikaʻi, e hāʻawi ana i ka hiki ke mālama i ka ikehu nui a me ka maʻemaʻe huahana kiʻekiʻe i nā ʻōnaehana PSA."
Ua hōʻoia nā loiloi hana kūʻokoʻa e hiki i ka oxygen i hana ʻia ma o nā ʻāpana PSA LXS ke hoʻokō i nā maʻemaʻe ma mua o 95% me nā helu hoʻōla i hoʻomaikaʻi ʻia. ʻO kēia ka mea e hoʻolilo ai i ka ʻenehana i mea hoihoi loa no ka hoʻolako oxygen lapaʻau waena, nā hale hana hoʻomaʻemaʻe wai ʻino e pono ai ka aeration kūpono, a me nā kaʻina hana metallurgical a me kemika like ʻole.
Ma waho aʻe o ka hana ʻana o ka oxygen, ʻo ke kaiapuni kū hoʻokahi o ka cation-rich o ka LXS zeolite e wehe ana i nā ala noiʻi hoʻohiki no nā hoʻokaʻawale ʻē aʻe, me ka hopu ʻana o ke kalapona dioxide mai nā kinoea flue a me ka hoʻomaʻemaʻe ʻana o nā kahawai hydrogen.
Hoʻomaopopo nā mea hana kālepa ʻo ka synthesis o LXS, ʻoiai e koi ana i ka kaohi pololei, hiki ke hoʻonui ʻia me ka hoʻohana ʻana i nā ʻano hydrothermal i hoʻokumu ʻia. Mālama ka mea i ka ikaika mechanical maikaʻi loa a me ke kūpaʻa o nā zeolites synthetic, e hōʻoiaʻiʻo ana i ka hana paʻa i nā hana PSA cyclic.
ʻO ka hoʻolauna ʻana o ka LXS zeolite hana kiʻekiʻe e manaʻo ʻia e hoʻolalelale i ka hoʻohana ʻana i ka ʻenehana PSA ma ke ʻano he koho hilinaʻi, ma ke koi ʻana i ka distillation cryogenic no ka hoʻolako oxygen, e kōkua ana i ka hana kinoea ʻoihana ʻoi aku ka maʻalahi a me ka decentralized.
E pili ana i nā Zeolites:
He mau minelala microporous nā Zeolites i hoʻohana pinepine ʻia ma ke ʻano he adsorbents a me catalysts. ʻO ko lākou nui pore like e ʻae iā lākou e hoʻokaʻawale i nā molekala ma muli o ka nui a me ka polarity, e lilo ai lākou i mea nui loa i nā ʻoihana kemika, petrochemical, a me ke kaiapuni.
