Ibisobanuro bigufi:

Zeolite ya molekile ya elegitoronike ni ubwoko bwa adsorbent cyangwa firime hamwe na micropores imwe, bigizwe ahanini na silicon, aluminium, ogisijeni hamwe nibindi byuma. Ingano yacyo ya pore ihwanye nubunini rusange bwa molekile, kandi molekile zitandukanye zamazi zishishwa ukurikije ubunini bwazo bwiza. Zeolite ya molekile ya elegitoronike bivuga ibyo bintu bisanzwe na sintetike ya kristaline aluminosilicates ifite imikorere ya sikeli ya molekile. Zeolite ya molekile ya elegitoronike yabaye ikintu cyigenga kubera imiterere yihariye n'imikorere. Ikoreshwa rya molekile ya zeolite yakwirakwiriye mu nganda za peteroli, kurengera ibidukikije, ubwubatsi bw’ibinyabuzima, inganda z’ibiribwa, imiti n’imiti n’izindi nzego. Hamwe niterambere ryinganda zitandukanye mubukungu bwigihugu, ibyifuzo byo gukoresha molekile ya zeolite ya molekile byaragutse cyane.

Imikorere ya Adsorption

Adorption ya molekile ya zeolite ni inzira yo guhindura umubiri. Impamvu nyamukuru ya adsorption ni ubwoko bw "imbaraga zo hejuru" zakozwe na rukuruzi ya rukuruzi ikora hejuru. Iyo amazi atembera, molekile zimwe mumazi zigongana hejuru ya adsorbent kubera kugenda bidasanzwe, bigatuma molekile yibanda hejuru. Mugabanye umubare wa molekile nkiyi mumazi kugirango ugere ku ntego yo gutandukana no kuyikuraho. Kubera ko nta mpinduka yimiti ihari muri adsorption, mugihe cyose tugerageje kwirukana molekile zibanze hejuru, icyuma cya zeolite kizongera kugira ubushobozi bwa adsorption. Iyi nzira ninzira ihindagurika ya adsorption, yitwa gusesengura cyangwa kuvugurura. Kubera ko icyuma cya zeolite cya molekile gifite ubunini bwa pore imwe, gusa iyo diameter ya dinamike ya molekile iba ntoya kuruta icyuma cya molekile ya zeolite irashobora kwinjira byoroshye imbere mumyenge ya kirisiti kandi ikamenyekana. Kubwibyo, icyuma cya molekile ya zeolite kimeze nkicyuma cya gaze na molekile zamazi, kandi byemejwe niba byamamazwa cyangwa bidakurikije ubunini bwa molekile. . Kubera ko icyuma cya zeolite cya molekuline gifite polarite ikomeye mu cyuho cya kristaline, kirashobora kugira ingaruka zikomeye ku buso bwa molekile ya zeolite ya molekile irimo amatsinda ya polar, cyangwa mugutera polarisiyasi ya molekile ya polarizable kugirango itange adsorption ikomeye. Ubu bwoko bwa molekile cyangwa polarike byoroshye byoroshye kwamamazwa na polarike ya zeolite ya molekile ya elegitoronike, ibyo bikaba byerekana ubundi buryo bwo guhitamo adsorption ya selekile ya zeolite.

Imikorere yo guhana

Muri rusange, guhana ion bivuga guhanahana indishyi hanze yurwego rwa molekile ya zeolite. Indishyi ion zitari murwego rwimashanyarazi ya zeolite muri rusange ni proton hamwe nicyuma cya alkali cyangwa ubutaka bwa alkaline, ibyo bikaba byoroshye guhinduranya ion mubyuma bitandukanye bya valence ibyuma byubwoko bwa zeolite ya molekile ya elegitoronike mugisubizo cyamazi yumunyu wicyuma. Ions biroroshye kwimuka mubihe bimwe na bimwe, nkibisubizo byamazi cyangwa ubushyuhe bwinshi.

Mu gisubizo cyamazi, bitewe nuburyo butandukanye bwo guhitamo ion ya molekile ya zeolite ya molekile, ibintu bitandukanye byo guhanahana ion birashobora kugaragara. Hydrothermal ion yoguhindura reaction hagati yicyuma na zeolite ya molekile ya elegitoronike ni inzira yo gukwirakwiza kubuntu. Igipimo cyo gukwirakwiza kigabanya igipimo cyo kuvunja.

Imikorere ya catalitiki

Zeolite ya molekile ya sikeli ifite imiterere yihariye ya kristu, buri kimwekimwe gifite imiterere ya pore yubunini nubunini runaka, kandi ifite ubuso bunini bwihariye. Amashanyarazi ya zeolite menshi afite centre ikomeye ya acide hejuru, kandi hariho umurima ukomeye wa Coulomb mumyobo ya kirisiti ya polarisiyasi. Ibi biranga bituma iba umusemburo mwiza. Heterogeneous catalitike reaction ikorwa kuri catalizator ikomeye, kandi ibikorwa bya catalitiki bifitanye isano nubunini bwa pisitori ya kirisiti ya catalizator. Iyo amashanyarazi ya zeolite akoreshwa nka catalizator cyangwa umutwara wa catalizator, iterambere ryibikorwa bya catalitiki bigenzurwa nubunini bwa pore ya molekile ya zeolite. Ingano nuburyo bya kristu ya pisitori na pore birashobora kugira uruhare muburyo bwo guhitamo. Mubihe rusange byimikorere, zeolite ya molekile ya elegitoronike igira uruhare runini mubyerekezo byerekana kandi ikerekana imiterere-ihitamo imikorere ya catalitiki. Iyi mikorere ituma molekile ya zeolite ikuramo ibintu bishya bya catalitiki ifite imbaraga zikomeye.
