Izisefo ze-molecular ze-Zeolite zinomphumela oqinile wokuhlukanisa ku-nitrogen nomoya-mpilo.Inesakhiwo kanye nezici zekristalu, indawo engaphezulu iwuhlaka lwamathambo aqinile, futhi imigodi yangaphakathi ingadlala indima yama-athomu adsorbing.Kunezimbotshana ezixhunywe komunye nomunye phakathi kwemigodi, futhi ama-molecule adlula ezimbotsheni.Ngenxa yemvelo ehlanzekile yama-pores, ukusabalalisa usayizi we-pore we-molecular sieve kufana kakhulu.Izisefo zamamolekyuli zikhetha ngokukhetha ama-molecule asuselwa kusayizi wezimbotshana ezingaphakathi kwamakristalu awo, okungukuthi, ama-molecule adsorb anosayizi othile kuyilapho exosha ama-molecule ezinto ezinkulu.
