3Isisefo semolekyuli

3Isisefo samangqamuzana i-alkali metal aluminate, ngezinye izikhathi ibizwa nangokuthi 3A zeolite molecular sieve.

Igama lesiNgisi: 3A Isihlungi Semolekyuli
Isilinganiso se-Silica / aluminium: SiO2/ Al2O3≈2
Usayizi wembotshana osebenzayo: cishe i-3A (1A = 0.1nm)

Isimiso sokusebenza sesisefo samangqamuzana sihlobene kakhulu nosayizi wembotshana yesisefo samangqamuzana, ngokulandelana kwawo 0.3nm/0.4nm/0.5nm, angakwazi ukukhangisa ama-molecule egesi anobubanzi bengqamuzana obuncane kunosayizi wembotshana, futhi uma bukhulu usayizi wembotshana, mkhulu umthamo we-adsorption.Ubukhulu bembobo buhlukile, futhi izinto ezihlungiwe zihlukile.Ngamagama alula, isisefo se-molecular 3a singakhanga ama-molecule angaphansi kuka-0.3nm kuphela.

3Isefa yemolekyuli inosayizi wembotshana ongu-3A, esetshenziswa kakhulu ukukhangisa amanzi, futhi ayikhangisi noma iyiphi i-molecule enobubanzi obungaphezu kuka-3A.Ngokwezici zokusetshenziswa kwemboni, isisefo samangqamuzana sinesivinini esisheshayo sokukhangisa, izikhathi zokukhiqiza kabusha, amandla okuchoboza kanye nekhono lokulwa nokungcola, okuthuthukisa ukusebenza kahle kwesisefo samangqamuzana futhi andise impilo yesevisi yesisefo samangqamuzana.Kuyimpahla ye-adsorption edingekayo yokomisa okujulile, ukucwengwa kanye ne-polymerization yesigaba soketshezi lwegesi embonini ye-petroleum namakhemikhali.
