Ibisobanuro
Molekile yibintu bitandukanye itandukanijwe nubunini nubunini bwa adsorption, bityo ishusho yitwa "icyuma cya molekile".
Amashanyarazi ya molekulari (azwi kandi nka zeolite ya syntetique) ni kirisiti ya silikatike.Nuburyo bwibanze bwa skeleton igizwe na silicon aluminate, hamwe nibyuma (nka Na +, K +, Ca2 +, nibindi) kugirango uhuze amafaranga arenze urugero muri kristu.Ubwoko bwa molekile ya elegitoronike igabanijwe cyane muburyo bwa A, ubwoko bwa X na Y ukurikije imiterere ya kristu.
| Imiti yimiti ya zeolite: | Mx / n [(AlO.2) x (SiO.2) y] KUKI.2O. |
| Mx / n:. | Cion ion, kugumya kristu idafite amashanyarazi |
| (AlO2) x (SiO2) y: | Igikanka cya kirisiti ya zeolite, hamwe nuburyo butandukanye bwimyobo n'imiyoboro |
| H2O: | kumubiri wumuyaga wamazi |
| Ibiranga: | Byinshi adsorption na desorption birashobora gukorwa |
| Andika icyuma cya molekulari | Ikintu cyingenzi cyubwoko bwa A molekulari ni silicon aluminate. Umwobo nyamukuru wa kirisiti ni octaring structure.Ubusembure bwingenzi bwa kristu ya aperture ni 4Å (1Å = 10-10m), izwi nkubwoko bwa 4A (bizwi kandi nubwoko A) icyuma cya molekile;
|
| Andika X Molecular Icyuma | Ikintu nyamukuru kigizwe na X molekulari ya silike ni silicon aluminate, umwobo nyamukuru wa kirisiti ni ibintu cumi na bibiri bigize impeta. Ca2 + yahinduye Na + mumashanyarazi ya 13X, ikora kristu ya molekile ya kirisiti ifite aperture ya 8-9 A, yitwa 10X (izwi kandi nka calcium X) icyuma cya molekile.

Gusaba
Kwiyongera kw'ibikoresho biva muri adsorption physique (vander Waals Force), hamwe na polarite ikomeye hamwe nimirima ya Coulomb imbere yumwobo wacyo wa kirisiti, byerekana ubushobozi bukomeye bwo kwinjiza molekile ya polarike (nkamazi) na molekile zidahagije.
Ikwirakwizwa rya aperture ya elegitoronike irasa cyane, kandi ibintu gusa bifite diameter ya molekile ntoya kurenza umwobo wa diameter bishobora kwinjira mu mwobo wa kirisiti imbere ya sikeli.
