- Limolek'hule tsa lintho tse fapaneng li khetholloa ke bohlokoa le boholo ba adsorption, kahoo setšoantšo se bitsoa "molecular sieve".
- Sieve ea molek'hule (eo hape e tsejoang e le zeolite ea maiketsetso) ke silicate microporous crystal.Ke motheo oa skeleton sebopeho se entsoeng ka silicon aluminate, e nang le li-cations tsa tšepe (tse kang Na +, K +, Ca2 +, joalo-joalo) ho leka-lekanya tefiso e mpe e feteletseng ka kristale.Mofuta oa sieve ea limolek'hule o arotsoe haholo ka mofuta oa A, mofuta oa X le mofuta oa Y ho latela sebopeho sa kristale.
| Mokhoa oa lik'hemik'hale oa lisele tsa zeolite | Mx/n [(AlO.2) x (SiO.2) y]WH.2O. |
| Mx/n. | Cation ion, ho boloka kristale e sa nke lehlakore ka motlakase |
| (AlO2) x (SiO2) y | Masapo a likristale tsa zeolite, tse nang le libopeho tse fapaneng tsa masoba le likanale |
| H2O | mouoane oa metsi o monyetleng oa 'mele |
| Likaroloana | Ho ka etsoa adsorption e ngata le desorption |
| Type Amolecular sieve | | Karolo e ka sehloohong ea mofuta oa A sieve ea molek'hule ke silicon aluminate.Lesoba le leholo la kristale ke sebopeho sa octaring.Sekoti sa lesoba le leholo la kristale ke 4Å(1Å=10-10m), e tsejoang e le mofuta oa 4A (o tsejoang hape e le mofuta oa A) sieve ea molek'hule;Fapanyetsana Ca2 + bakeng sa Na + ho sefe ea 4A molek'hule, ho etsa lesoba la 5A, e leng mofuta oa 5A (aka calcium A) sieve ea molek'hule;K+ bakeng sa sefe ea 4A ea molek'hule, e etsa lesoba la 3A, e leng 3A (aka potassium A) sieve ea molek'hule. |

- The adsorption ea lintho tse bonahalang e tsoa ho 'mele adsorption (vander Waals Force), ka polarity matla le masimo Coulomb ka hare ho lesoba la kristale, ho bontša matla adsorption bokgoni bakeng sa limolek'hule polar (joaloka metsi) le limolek'hule unsaturated.
- Kabo ea sekoti ea sieve ea limolek'hule e tšoana haholo, 'me ke lintho feela tse nang le bophara ba molek'hule tse nyane ho feta bophara ba lesoba li ka kenang lesoba la kristale ka har'a sieve ea limolek'hule.
