Wehewehena a me nā hiʻohiʻona

Wehewehe: Hoʻohana ʻo WNX i ka ʻenehana hana hana automated holomua a hoʻohana i nā mea maka kiʻekiʻe e hana i nā mea kiʻekiʻeʻO ka nui o nā ʻāpana Cerium Oxide.

Nā Hiʻohiʻona Koʻikoʻi:

Maʻemaʻe Kiʻekiʻe:ʻO ka nui o nā ʻāpana Cerium Oxide

ʻaʻohe mea haumia mai nā mea honua laha ʻole (e like me ka hao, calcium, sodium), a haʻahaʻa ka nui o ka haumia.

Ka hoʻoheheʻe maikaʻi:ʻO ka nui o nā ʻāpana Cerium Oxide

hiki ke hoʻoheheʻe koke i ka wai a me nā waikawa ikaika.

Kūlike: ʻO ka hoʻokele puʻupuʻu koʻikoʻi i ka hana ʻana oʻO ka nui o nā ʻāpana Cerium Oxide

hōʻoia i ka maikaʻi paʻa no ka hana ʻana i ka ʻoihana nui.

Nā mea hoʻouluulu ʻoihana kemika: ʻOʻO ka nui o nā ʻāpana Cerium Oxide, ma muli o kona ikaika mechanical kiʻekiʻe a me ke kūpaʻa, hoʻohana ʻia ʻo ia ma ke ʻano he mea lawe catalyst maikaʻi loa i nā reactors moena paʻa e pono ai ke kū i ke kaomi kiʻekiʻe a i ʻole nā hopena kahe wikiwiki. Hiki iā ia ke hoʻouka pono i nā metala makamae (e like me ka platinum a me ka palladium) a hoʻohana ʻia i nā kaʻina hana e like me ka hydrogenation i loko o nā petrochemicals, e hoʻolōʻihi nui ana i ke ola lawelawe o ka catalyst. ʻO kona mau ʻano kīnā hakahaka oxygen kū hoʻokahi e hoʻolilo iā ia i mea nui i ka hoʻomaʻemaʻe ʻana i ka hoʻopau kaʻa (nā mea hoʻololi catalytic ʻekolu ala), e paipai ana i ka hoʻololi ʻana o ke kalapona monoxide (CO), hydrocarbons (HC), a me nā nitrogen oxides (NOx).

Luna Hoʻohemo Phosphorus o ka loko: ʻOʻO ka nui o nā ʻāpana Cerium Oxide hiki i nā ʻāpana ke hoʻopili pono a hoʻoulu i nā ion phosphate i loko o ke kino wai, a laila e kāohi ana i ka ulu ʻana o ka algae a hoʻoponopono i ka pilikia o ka eutrophication o ke kino wai. He nui iki ka nui o ka ʻāpana, a ʻoi aku ka maikaʻi o kāna hana sedimentation i nā noi kino wai maoli, e maʻalahi ai ka hoʻōla hou ʻana a me ka hōʻemi ʻana i ka pilikia o ka haumia lua.

Nā Pākahi a me nā Mea Ikehu: I loko o nā pūnaewele wahie oxide paʻa (SOFC),ʻO ka nui o nā ʻāpana Cerium Oxide hiki ke hoʻohana ʻia ma ke ʻano he mea electrolyte. ʻO kona kūpaʻa palena grain kiʻekiʻe e kōkua i ka hoʻonui ʻana i ka conductivity ionic a me ka lōʻihi o ka hana o ka pila. Eia kekahi, hiki ke hoʻohana ʻia ma ke ʻano he mea maka no ka hoʻomākaukau ʻana i nā alloys mālama hydrogen no ka electrode maikaʻi ʻole o nā pila nickel-hydrogen, a i ʻole no ka hoʻololi ʻana i nā mea electrode pila lithium-ion, no laila e hoʻomaikaʻi ana i ka hana kaʻapuni o ka pila ma o kona ʻano paʻa.

Nā waena hana kemika:ʻO ka nui o nā ʻāpana Cerium Oxide he mea hoʻomaka koʻikoʻi ia no ka hana ʻana i nā mea hana ʻē aʻe i hoʻokumu ʻia i ka cerium (e like me nā paʻakai cerium, ka cerium oxide i hoʻohui ʻia, a pēlā aku). Ma o ka hana kemika hou aʻe, hiki ke hoʻololi ʻia i loko o nā hui cerium me nā ʻano a me nā waiwai kikoʻī, i hoʻohana ʻia ma nā kahua e like me nā keramika uila a me nā mea absorption ultraviolet.
