Amashanyarazi ya molekulari 3A, azwi kandi ku izina rya molekile ya sivile KA, hamwe na aperture ya angstroms zigera kuri 3, irashobora gukoreshwa mu kumisha imyuka n’amazi kimwe no kubura umwuma wa hydrocarbone.Ikoreshwa kandi mukumisha burundu peteroli , imyuka yamenetse, Ethylene, propylene na gaze gasanzwe.
Ihame ryakazi rya molekile ya molekile ifitanye isano cyane nubunini bwa pore ya molekile ya molekile, ni 0.3nm / 0.4nm / 0.5nm.Bashobora kwamamaza molekules ya gaze ifite diameter ya molekile ntoya kuruta ubunini bwa pore.Ninini yubunini bwa pore, nubushobozi bwa adsorption.Ingano ya pore iratandukanye, kandi ibintu bishungura kandi bitandukanijwe nabyo biratandukanye.Mumagambo yoroshye, icyuma cya molekula 3a gishobora gusa molekules ya adsorb munsi ya 0.3nm, 4a ya molekile ya molekile, molekile ya adsorbed nayo igomba kuba munsi ya 0.4nm, kandi 5a ya molekile ya molekile nimwe.Iyo ikoreshejwe nka desiccant, icyuma cya molekile kirashobora gukuramo 22% byuburemere bwacyo mubushuhe.
