Hōʻike Pōkole:

ʻO ka sieve molekole Zeolite kahi ʻano adsorbent a i ʻole mea kiʻi ʻoniʻoni me nā micropores like, i haku ʻia me ka silikona, aluminika, oxygen a me kekahi mau cations metala ʻē aʻe. Ua like ka nui o kona pore me ka nui o ka nui o ka mole, a ua kānana ʻia nā mole kūmole like ʻole e like me ka nui o kona pore. ʻO ke kāne molekole Zeolite e pili ana i kēlā mau aluminosilicates crystalline kūlohelohe a synthetic i loaʻa ka hana sieve molekole. Ua lilo ʻo siolve mololo Zeolite i kumuhana kūʻokoʻa ma muli o kāna hanana kū hoʻokahi a me kāna hana. Ua pālahalaha ʻia ka noi o ka sieve mole zeolite i ka ʻoihana petrochemical, ka pale ʻana i ke kaiapuni, ka hana ʻana i nā meaola, ka ʻoihana meaʻai, nā mea lāʻau lapaʻau a me nā ʻoihana kemika a me nā wahi ʻē aʻe. Me ka hoʻomohala ʻana o nā ʻoihana like ʻole i ka hoʻokele waiwai aupuni, ua hoʻonui ka laulā o nā noi noi o nā sieves mole zeolite.

Hana Adsorption

ʻO ka adsorption o ka sieve mole mole zeolite kahi hana hoʻololi kino. ʻO ke kumu nui o ka adsorption kahi ʻano o "ka ikaika o ka ʻili" i hana ʻia e ka umekaumaha molekiola e hana ana i ka ʻili paʻa. Ke kahe ka wai i loko, kuʻi kekahi mau mole i ka wai i ka ʻili o ka adsorbent ma muli o ka neʻe ʻole o ke neʻe ʻana, e hoʻoulu ana i ka moleola ma luna. E hoʻemi i ka helu o ia mau mole i ka wai e loaʻa ai ke kumu o ka hoʻokaʻawale a me ka hemo ʻana. Ma muli o ka loli ʻole o ka adsorption, ʻoiai mākou e hoʻāʻo e kipaku aku i nā mole i pili i ka ʻili, e loaʻa hou i ka sieve mole zeolite i ka adsorption. ʻO kēia kaʻina ke kaʻina hana hope o ka adsorption, i kapa ʻia ka anamanaʻo a i ʻole ke ola hou ʻana. Ma muli o ke ʻano o ka sieve mole zeolite i ka nui pore, aia wale nō ka liʻiliʻi o ke anawaena o ka mika mika ma mua o ke kānana mole zeolite hiki ke maʻalahi ke komo i loko o ka lua aniani a hoʻolaha ʻia. No laila, ua like ka sieve mole mole zeolite me kahi sieve no ka mole a me nā mole wai, a ua hoʻoholo ʻia inā e hoʻolaha ʻia a i ʻole ʻaʻole e like me ka nui o ka mole. . ʻOiai he polarity ikaika ka sieve mole zeolite i ka lua crystalline, hiki iā ia ke hopena ikaika ma luna o ka sieve mole zeolite me nā mole i loko o nā hui polar, a i ʻole ka hoʻoulu ʻana i ka polarization o nā mole polarizable e hana i ka adsorption ikaika. Maʻalahi ke hoʻolaha ʻia kēia ʻano polar a i ʻole polarized maʻalahi e nā poli zeolite mole sieve, e hōʻike ana i kahi koho adsorption o ka sieve mole zeolite.

Hana pānaʻi Ion

Ma ka ʻōlelo maʻamau, pili ka ion i ka hoʻololi o nā cation uku ma waho o ke kuhi o ka sieve mole zeolite. ʻO nā ion uku ma waho o ke kuhi o ka sieve mole mole zeolite he protons a me nā metala alkali a i ʻole nā ​​metala honua alkaline, i hoʻololi maʻalahi ʻia i ion i nā ʻano valence metala ion-type zeolite mole sieves i loko o ka wai aqueous solution o nā paʻakai metala. Maʻalahi ka neʻe ʻana o nā ion i lalo o kekahi mau ʻano, e like me nā wai aqueous a i ʻole nā ​​mahana kiʻekiʻe.

I ka hopena wai, ma muli o ke koho ion ʻokoʻa o nā sieves mole mole zeolite, hiki ke hōʻike ʻia nā ʻano hoʻololi ion like ʻole. ʻO ka hydrothermal ion exchange reaction ma waena o nā cations metala a me nā sieves mole mole zeolite kahi hana diffusion manuahi. Hoʻopau ka helu diffusion i ka pālākiō o ka pānaʻi hoʻololi.

Hana catalytic

Loaʻa i nā sieves moleola Zeolite kahi hanana aniani maʻamau maʻamau, ʻo kēlā me kēia me kahi pore o kahi nui a me kona ʻano, a he nui kahi kikoʻī kikoʻī. ʻO ka hapa nui o nā sieves mole mole zeolite he mau kikowaena waikawa ikaika ma ka ʻili, a aia kahi māla Coulomb ikaika i nā pores aniani no ka polarization. ʻO kēia mau hiʻohiʻona e hoʻolilo iā ia i catalyst maikaʻi loa. Lawe ʻia nā hopena catalytic hetero ma nā catalst paʻa, a pili ka hana catalytic i ka nui o nā pores aniani o ka catalyst. Ke hoʻohana ʻia kahi sieve mole mole zeolite ma ke ʻano he catalyst a i ʻole he catalyst carrier, ʻo ka holomua o ka hopena catalytic ka mea e ka nui pore o ka sieve mole zeolite. Hiki i ka nui a me ke ʻano o nā pores aniani a me nā pores ke pāʻani i kahi kuleana i ka hopena catalytic. Ma lalo o nā kūlana maʻamau, hana nui nā kānana mole zeolite i ke ʻano o ka hopena a hōʻike i ka hana catalytic i wae ʻia. Hana kēia hana i nā sieves mole zeolite i kahi mea catalytic hou me ka ikaika ikaika.
