5A molecular sieve pore loj rau 5A, tuaj yeem nqus tau tsawg dua txoj kab uas hla ntawm ib qho molecule, feem ntau yog siv hauv kev sib cais sib cais hydrocarbon sib cais, siab viav vias adsorption, sib cais adsorption thiab dej thiab carbon dioxide, raws li kev siv cov yam ntxwv ntawm 5A molecular sieve, peb hauv kev tsim cov 5A molecular sieve xaiv qhov siab adsorption, nrawm adsorption, tshwj xeeb tshaj yog haum rau lub siab viav vias adsorption, tuaj yeem hloov kho rau txhua yam loj ntawm cov pa, hydrogen, carbon dioxide thiab lwm yam roj siab viav vias adsorption ntaus ntawv, yog qhov zoo cov khoom lag luam hauv kev lag luam siab viav vias adsorption (PSA).
