Kufotokozera Kwachidule:

Zeolite sieve ya molekyulu ndi mtundu wa adsorbent kapena kanema wokhala ndi ma micropores yunifolomu, makamaka opangidwa ndi silicon, aluminium, oxygen ndi zida zina zachitsulo. Kukula kwake kwa pore ndikofanana ndi kukula kwa ma molekyulu, ndipo mamolekyulu osiyanasiyana amadzimadzi amasefa molingana ndi kukula kwake kwa pore. Zeolite sieve molekyulu amatanthauza zinthu zachilengedwe komanso zopangidwa ndi crystalline aluminosilicates zomwe zimakhala ndi sieve yama cell. Zeolite sieve yamaselo yakhala nkhani yodziyimira payokha chifukwa cha kapangidwe kake kapangidwe kake ndi magwiridwe ake. Kugwiritsa ntchito sefa ya molekyulu yafalikira kumakampani opanga petrochemical, kuteteza zachilengedwe, zomangamanga, mafakitale azakudya, makampani opanga mankhwala ndi mankhwala ndi magawo ena. Ndikukula kwa mafakitale osiyanasiyana mu chuma cha dziko, chiyembekezo chazomwe agwiritse ntchito a siolite molekyulu yakula kwambiri.

Ntchito yotsatsa

Kutsatsa kwa seolite molekyulu ndikusintha kwakuthupi. Chifukwa chachikulu choberekera ndi mtundu wa "mphamvu yakumtunda" yopangidwa ndi mphamvu yokoka yamagulu yomwe imakhala yolimba. Madzi akamadutsa, mamolekyulu ena amadzimadziwo amaphatikizana ndi nkhope ya adsorbent chifukwa chosayenda mokhazikika, ndikupangitsa kuti maselo azikhala pamwamba. Kuchepetsa kuchuluka kwa mamolekyulu otere m'madzi kuti akwaniritse cholinga chodzipatula ndikuchotsa. Popeza palibe kusintha kwamankhwala pakubwezeretsa kwina, bola ngati titayesa kuthamangitsa mamolekyuluwo omwe amakhala pamwamba, seeve ya molekyulu ya zeolite idzakhalanso ndi mphamvu yobwezeretsanso. Njirayi ndi njira yobwezera kutsatsa, komwe kumatchedwa kusanthula kapena kukonzanso. Popeza sefa ya molekyulu ya zeolite imakhala ndi pore yofananira kukula, pokhapokha mphamvu yamagulu yaying'ono ikakhala yaying'ono kuposa seolite molekyulu imatha kulowa mkatikati mwa kristalo ndikutsitsidwa. Chifukwa chake, sefa ya molekyulu ya zeolite ili ngati sefa ya mamolekyulu amafuta ndi amadzimadzi, ndipo imatsimikizika ngati ipangidwenso kapena ayi kutengera kukula kwa molekyuluyo. . Popeza sefa ya molekyulu ya zeolite imakhala ndi polarity yolimba kwambiri m'makristalo, imatha kukhala ndi mphamvu yayikulu pamwamba pa sefa ya molekyulu yokhala ndi mamolekyulu okhala ndi magulu a polar, kapena poyambitsa kugawanika kwa mamolekyulu omwe amatha kupangika kuti apange kutulutsa kwamphamvu. Mitundu iyi yama polar kapena yolowetsedwa mosavuta ndiyosavuta kutsitsidwa ndi polar zeolite sieve ya molekyulu, yomwe ikuwonetsa kusankhanso kwina kosankha kwa siolite molekyulu.

Kusintha kwa Ion

Nthawi zambiri, kusinthana kwa ion kumatanthawuza kusinthana kwa ziphuphu kunja kwa chimango cha zeolite. Ma ayoni operekera ndalama kunja kwa chimango cha zeolite sieve nthawi zambiri amakhala ma proton ndi zitsulo za alkali kapena zitsulo zamchere zamchere, zomwe zimasinthidwa mosavuta ma valence iron ion-mtundu wa zeolite molekyulu mumayendedwe amchere amchere. Ion imasunthira mosavuta pamikhalidwe ina, monga madzi amadzimadzi kapena kutentha kwambiri.

Mu yankho lamadzimadzi, chifukwa chosankha kosiyanasiyana kwa ma seole a molekyulu, ziwonetsero zosiyanasiyana za ion zitha kuwonetsedwa. Ma hydrothermal ion exchange reaction pakati pazitsulo zamatope ndi zeolite ma molekyulu ndi njira yofalitsira kwaulere. Kuchuluka kwa mayendedwe kumalepheretsa kuchuluka kosinthira.

Ntchito Catalytic

Masekeli a Zeolite amakhala ndi mawonekedwe apadera a kristalo, iliyonse yomwe ili ndi mawonekedwe a pore a kukula kwake ndi mawonekedwe ake, ndipo ili ndi gawo lalikulu pamtunda. Mitundu yambiri yama zeolite imakhala ndi malo olimba acid pamtunda, ndipo pali gawo lamphamvu la Coulomb m'makristalo opangira polarization. Makhalidwewa amachititsa kukhala chothandizira kwambiri. Kuchita mosiyanasiyana kwa othandizira kumachitika pazolimba zolimbitsa thupi, ndipo zochitikazo zimakhudzana ndi kukula kwa ma crystal pores a chothandizira. Pamene sefa ya molekyulu imagwiritsidwa ntchito ngati chothandizira kapena chothandizira chothandizira, kupita patsogolo kwa zomwe zimathandizira kumayang'aniridwa ndi kukula kwa pore wa siolite molekyulu. Kukula ndi mawonekedwe a ma pores ndi ma pores amatha kutengapo gawo pazomwe zimathandizira. Pazomwe zimachitika, ma seole a molecular zeolite amatsogolera pakuwongolera ndikuwonetsa magwiridwe antchito othandizira othandizira. Kuchita kumeneku kumapangitsa ma zeolite sieve kukhala chinthu chatsopano chothandiza kwambiri.
