Loaʻa i nā kānana molekala Zeolite kahi hopena hoʻokaʻawale ikaika i ka nitrogen a me ka oxygen.Loaʻa iā ia ke ʻano a me nā hiʻohiʻona o kahi aniani, ʻo ka ʻili he iwi paʻa, a hiki i nā lua o loko ke pāʻani i ka hana o nā molekala adsorbing.Aia nā pores i hoʻopili ʻia kekahi i kekahi ma waena o nā lua, a hele nā ​​molekala i nā pores.Ma muli o ke ʻano maʻemaʻe o nā pores, ʻokoʻa loa ka puʻupuʻu pore o ka sieve molecular.ʻO nā kānana molekole e hoʻopili i nā molekole e pili ana i ka nui o nā pores i loko o kā lākou mau kristal, ʻo ia hoʻi, adsorb molekala o kekahi nui aʻo ka hoʻihoʻi ʻana i nā molekala o nā mea nui.
