Nā ʻano o nā adsorbents like ʻole
Kalapona i hoʻāla ʻia:He ʻano microporous a me mesoporous waiwai kona, me kahi ʻili kikoʻī ma kahi o 500-1000m2/g, a me ka hoʻokaʻawale ʻana o ka nui o ka pore ma waena o 2-50nm. Hilinaʻi nui ke kalapona i hoʻāla ʻia ma ka ikaika van der Waals i hana ʻia e ka adsorbate e hana i ka adsorption, a hoʻohana nui ʻia no ka adsorption a me ka wehe ʻana i nā hui organik, nā hui organik hydrocarbon kaumaha, a me nā deodorants;
Kānana molekala:Loaʻa iā ia kahi ʻano pore microporous maʻamau me kahi ʻāpana ʻili kikoʻī ma kahi o 500-1000m2/g, i haku ʻia me nā micropores, me ka hoʻokaʻawale ʻana o ka nui o ka pore ma waena o 0.4-1nm. Hiki ke hoʻololi ʻia nā ʻano adsorption o nā sieves molekala ma ka hoʻoponopono ʻana i ko lākou ʻano, ka haku mele ʻana, a me ke ʻano o nā cations kaulike. Hilinaʻi nui nā sieves molekala i ke ʻano pore ʻano a me ke kahua ikaika Coulomb ma waena o nā cations kaulike a me ke ʻano sieve molekala e hana i ka adsorption. Loaʻa iā lākou ke kūpaʻa thermal a me hydrothermal maikaʻi a hoʻohana nui ʻia i ka hoʻokaʻawale ʻana a me ka hoʻomaʻemaʻe ʻana i nā ʻano kinoea a me nā wai like ʻole. Ke hoʻohana ʻia e like me nā adsorbents, loaʻa i nā sieves molekala ke koho ikaika, ka hohonu adsorption kiʻekiʻe, a me ka hiki ke adsorption nui;
ʻO ka gel silica:ʻO ka ʻili o ka mea hoʻomoʻa ʻano silicone he 300-500m2/g ka nui o ka ʻili, me ka mesoporous, me ka hoʻolaha ʻana o ka nui o ka pore o 2-50nm. Loaʻa i ka ʻili o loko o kona mau kahawai pore he nui nā hui hydroxyl o ka ʻili, i hoʻohana nui ʻia no ka hoʻomaloʻo adsorption a me ka adsorption swing pressure e hana i ka CO2;
ʻO ka alumina i hoʻāla ʻia:Me kahi ʻili kikoʻī o 200-500m2/g, he mesoporous nui ia a he 2-50nm ka nui o ka pore. Hoʻohana nui ʻia no ka hoʻomaloʻo ʻana, ka dehydration, ka hoʻomaʻemaʻe ʻana i ke kinoea ʻōpala waikawa, a pēlā aku.
