Isihlungi sama-molecule esingu-4A kanye nesihlungi sama-molecule esingu-13X

4Ifomula yekhemikhali ye-molecular sieve: Na₂O·Al₂O₃·2SiO₂·4.5H₂O ₃
Umgomo wokusebenza wesihlungi sama-molecule uhlobene kakhulu nosayizi wembobo yesihlungi sama-molecule, esingamunca ama-molecule egesi anobubanzi bama-molecule obuncane kunosayizi wembobo, futhi uma usayizi wembobo umkhulu, kulapho amandla okumunca abe makhulu khona. Usayizi womhubhe uhlukile, futhi izinto ezihlungiwe zihlukile. 4a isihlungi sama-molecule, ama-molecule afakwe isihlungi kumele abe ngaphansi kuka-0.4nm
Izisefo zama-molecule ze-4A zisetshenziswa kakhulu ukomisa igesi yemvelo kanye namagesi ahlukahlukene amakhemikhali kanye noketshezi, iziqandisi, izidakamizwa, idatha ye-elekthronikhi kanye nezinto eziguquguqukayo, ukuhlanza i-argon, nokuhlukanisa i-methane, i-ethane ne-propane. Zisetshenziswa kakhulu ukomisa ngokujulile amagesi kanye noketshezi njengomoya, igesi yemvelo, ama-hydrocarbon kanye neziqandisi; Ukulungiselela nokuhlanzwa kwe-argon; Ukomisa okuqinile kwezingxenye ze-elekthronikhi nezinto ezibolayo; Izinto eziqeda amanzi kupende, ama-polyester, amadayi kanye nezingubo.

Isihlungi sama-molecule sohlobo lwe-13X, esaziwa nangokuthi isihlungi sama-molecule sohlobo lwe-sodium X, siyi-alkali metal silicaluminate, sinohlobo oluthile lwe-alkali, singesesigaba sezisekelo eziqinile.
Ifomula yayo yamakhemikhali yi-Na2O· Al2O3·2.45SiO2·6.0H20,
Usayizi wayo wembobo ungu-10A futhi imunca noma yiliphi i-molecule engaphezu kuka-3.64A kanye nangaphansi kuka-10A
I-13x isetshenziswa kakhulu ku:
1) Ukuhlanzwa kwegesi kudivayisi yokuhlukanisa umoya ukuze kususwe amanzi kanye ne-carbon dioxide.
2) Ukomisa nokususa i-sulfurization yegesi yemvelo, igesi kaphethiloli encibilikisiwe kanye nama-hydrocarbon aketshezi.
3) Ukomisa ukujula kwegesi okuvamile. Isihlungo sama-molecule sohlobo lwe-13X, esaziwa nangokuthi isihlungo sama-molecule sohlobo lwe-sodium X, siyi-alkali metal silicaluminate, sinohlobo oluthile lwe-alkaline, singesesigaba sezisekelo eziqinile.
