Morero: Sieve ea Carbon Molecular ke sehlahisoa se secha se ntlafalitsoeng lilemong tsa bo-1970, ke sesebelisoa sa khabone se se nang polar, Carbon Molecular Sieves (CMS) se sebelisetsoang ho arola naetrojene e matlafatsang moea, ka ho sebelisa mokhoa oa phapusi khatello e tlase ea naetrojene, ho feta mokhoa oa setso o batang o matla o phahameng. khatello ea naetrojene e na le litšenyehelo tse fokolang tsa matsete, Lebelo le phahameng la tlhahiso ea naetrojene le theko e tlase ea naetrojene. Ka hona, ke indasteri ea boenjiniere e khethang khatello ea "swing adsorption" (PSA) moea karohano ea nitrogen rich adsorbent, naetrojene ena e sebelisoa haholo indastering ea lik'hemik'hale, indasteri ea oli le khase, indasteri ea lisebelisoa tsa elektroniki, indasteri ea lijo, indasteri ea mashala, indasteri ea meriana, indasteri ea cable, tšepe. phekolo ea mocheso, lipalangoang le polokelo le likarolo tse ling.
