Ke kumu: ʻO Carbon Molecular sieve he adsorbent hou i hoʻomohala ʻia i ka makahiki 1970, he mea maikaʻi loa ia non-polar carbon material, Carbon Molecular Sieves (CMS) i hoʻohana ʻia e hoʻokaʻawale i ka ea enrichment nitrogen, me ka hoʻohana ʻana i ke kaʻina hana haʻahaʻa haʻahaʻa haʻahaʻa, ma mua o ke anuanu kiʻekiʻe. ʻoi aku ka liʻiliʻi o ke kaʻina hana naikokene, ʻoi aku ka wikiwiki o ka hana ʻana o ka nitrogen a me ke kumu kūʻai haʻahaʻa. No laila, ʻo ia ka makemake o ka ʻenehana ʻoihana ʻoihana puʻe koʻi adsorption (PSA) air separation nitrogen rich adsorbent, ua hoʻohana nui ʻia kēia nitrogen i ka ʻoihana kemika, ka aila a me ka ʻoihana kinoea, ʻoihana uila, ʻoihana meaʻai, ʻoihana lanahu, ʻoihana lāʻau lapaʻau, ʻoihana kelepona, metala. ka mālama wela, ka lawe ʻana a me ka mālama ʻana a me nā mea ʻē aʻe.
