3Isefa yemolekyuli

I-3A i-molecular sieve yintsimbi yealkali, ngamanye amaxesha ikwabizwa ngokuba yi-3A zeolite molecular sieve.

Igama lesiNgesi: 3A Molecular Sieve
Umlinganiselo weSilica / aluminium: SiO2/ Al2O3≈2
Ubungakanani bepore obusebenzayo: malunga ne-3A (1A = 0.1nm)

Umgaqo wokusebenza we-molecular sieve unxulumene ubukhulu becala nobungakanani bepore yesihluzo semolekyuli, ngokulandelelanayo 0.3nm/0.4nm/0.5nm, banokubhengeza iimolekyuli zerhasi ezinobubanzi bemolekyuli buncinci kunobukhulu bepore, kwaye ubukhulu bepore, mkhulu umthamo we-adsorption.Ubungakanani bendawo yokuvula yahlukile, kwaye izinto ezihluziweyo zahlukile.Ngamagama alula, i-3a ye-molecular sieve inokubhengeza kuphela iimolekyuli ezingaphantsi kwe-0.3nm.

3Isefa yemolekyuli inobungakanani bepore obuyi-3A, esetyenziswa ikakhulu ukubhengeza amanzi, kwaye ayibhengezi nayiphi na imolekyuli enobubanzi obungaphezulu kwe-3A.Ngokweempawu zokusetyenziswa kwemizi-mveliso, i-molecular sieve inesantya esikhawulezayo sokubhengeza, amaxesha okuhlaziya, amandla okutyumza kunye nobuchule bokuchasana nongcoliseko, okuphucula ukusebenza kakuhle kwesihluzo semolekyuli kunye nokwandisa ubomi benkonzo ye-molecular sieve.Yimathiriyeli ye-adsorption eyimfuneko yokomisa okunzulu, ukucokisa kunye ne-polymerization yesigaba solwelo lwegesi kwi-petroleum kunye neshishini lemichiza.
