ʻO kekahi o nā hiʻohiʻona nui o kā mākou alumina i hoʻāla ʻia ʻo ia kona ʻano spherical, kahi e hoʻonui ai i kona pono e like me ka adsorbent ʻaila kaomi. ʻO kēia mau ʻāpana porous keʻokeʻo he ʻano like ka nui a me ka ʻili maʻalahi no ka adsorption maikaʻi loa a me ka kānana. ʻO ka ikaika mechanical kiʻekiʻe o ka alumina i hoʻāla ʻia e hōʻoia i ka mālama ʻana i kona ʻano kumu ʻoiai ma hope o ka lawe ʻana i ka wai, me ka ʻole o ka pehu ʻana a i ʻole ka pohā. Hōʻoia kēia i kona lōʻihi a me ka lōʻihi i nā noi like ʻole.
ʻO kekahi hiʻohiʻona ʻē aʻe o ka alumina hoʻāla ʻia ʻo kona hygroscopicity ikaika, kahi e hiki ai iā ia ke wehe pono i nā molekole wai. ʻO kēia ka mea e hana ai i kahi desiccant maikaʻi loa, ʻoi loa i nā noi kahi e koi ʻia ai ka maloʻo hohonu. ʻAʻole ʻona, ʻono ʻole, ʻaʻole hiki ke hoʻololi ʻia i ka wai a me ka ethanol, kahi e hōʻoia ai i kona palekana i nā ʻano like ʻole. ʻO kona kūpaʻa wela maikaʻi e mālama i ka hana maʻamau a hiki i nā wela kiʻekiʻe.
Hoʻohui ʻia, ua hoʻolālā ʻia kā mākou alumina i hoʻolaʻa ʻia e kūpono me nā ʻāpana hoʻōla wela ʻole, e hāʻawi ana i kahi hopena kūpono no ka hoʻohana mau ʻana. ʻO kēia hiʻohiʻona ka mea i koho nui a hilinaʻi no nā ʻoihana e like me ka aila a me ke kinoea, petrochemical, pharmaceutical, a me nā mea hou aku. ʻOiai ma hope o ka hoʻohana pinepine ʻana, mālama ia i kona ʻano kumu a me kāna hana, e hōʻoia ana i ka paʻa a me ka hilinaʻi i ke kaʻina kānana.
I ka hopena, ʻo ka alumina hoʻāla ʻia he hopena kūpono a maʻalahi no nā catalysts a me nā kākoʻo catalyst i nā hopena kemika. Me kona ʻāpana kiko kikoʻī nui, kūpaʻa wela maikaʻi a me ka hana adsorption ikaika, he koho maikaʻi loa ia no kahi ākea o nā noi. ʻO kona ʻano spherical, ka ikaika mechanical kiʻekiʻe a me ka hygroscopicity e lilo ia i mea hoʻoheheʻe ʻaila ʻaila adsorbent, kūpono no ka maloʻo hohonu a me ka kānana. E hilinaʻi i kā mākou alumina hana e hoʻokō i kāu mau pono ʻoihana a ʻike i ka mana o nā mea catalytic kiʻekiʻe.
