Carbon Molecular Sieve

Cov pa roj carbon molecular sieve siv nws cov khoom sieving kom ua tiav kev sib cais ntawm oxygen thiab nitrogen. Cov ntsiab lus tseem ceeb yog cov pa roj carbon monoxide, nrog cov xim dub columnar khoom zoo li (inch 1-2mm, qhov siab 2-5mm). Vim muaj coob tus micropores (nrog rau txoj kab uas hla ntawm 4 angstroms) nrog muaj zog instantaneous affinity rau oxygen molecules, lawv feem ntau yog siv los cais oxygen thiab nitrogen los ntawm huab cua, thiab ces tsim nitrogen los ntawm lub siab viav vias adsorption ntaus ntawv.
