ʻO Datong Heneng activated carbon Co., Ltd. （HNAC) i hoʻokumu ʻia i ka makahiki 2002.09 a hoʻokomo ʻia i loko o ka hana i ka makahiki 2003.08 he ʻoihana hoʻōla hohonu kalapona i hana ʻia ma Kina.

Loaʻa i ka HNAC nā kapuahi carbonizing ʻelua, hoʻokahi laina hana kaomi kalapona, 8 SLEP 800 mau kapuahi hoʻāla, 5 sets o sieving, wāwahi a me ka wehe ʻana i nā pōhaku e kākoʻo ana i nā laina hana, ʻelua pūʻulu o ka waika a me ka holoi holoi ʻana i nā laina hana hohonu, 4 mau moena hoʻoheheʻe ʻia, ka hoʻopili ʻana i ka lepo. laina, a me nā lako hana kākoʻo a me nā keʻena hoʻāʻo piha me ka automation kiʻekiʻe a me ka ʻenehana kiʻekiʻe. Hoʻomaloʻo ʻia ke kalapona i hoʻōla ʻia ma o ka moena wai hoʻoheheʻe ʻia kahi e wela ai ka ea e ka mahu wai wela. ʻO ka holoi ʻana i ka carbon activated me ka wai distilled hiki ke pale i ka haumia hiki ke hoʻomaikaʻi nui i ka maikaʻi o nā huahana i hoʻopau ʻia. Eia kekahi, aia ma ke kikowaena o ka ʻoihana lanahu, loaʻa iā HNAC ka pōmaikaʻi e ʻike i ka hana paʻa a hoʻomaikaʻi i ka maikaʻi. No laila, hiki i ka HNAC ke hana i nā ʻano kalapona hoʻōla kiʻekiʻe ma nā ʻano ʻokoʻa, ʻoi aku ka nui o nā mea kūʻai aku me nā koi kiʻekiʻe loa o ka carbon activated.

Hoʻopuka ʻo HNAC i kēlā me kēia makahiki i ka carbon activated 25000 tons, me ka carbon activated haʻihaʻi maʻamau 5000 tons, acid wasshed activated carbon 5000 tons, kaomi i ke kalapona hoʻoikaika ʻia 5000 tons, pauka i hoʻāla ʻia ka carbon 5000 tons, kānana mea kānana i hoʻāla ʻia 5000 tons. Hoʻokaʻawale ʻia nā huahana i 10 pūʻulu me ka desulfurization, decolorization, ka hoʻomaʻemaʻe wai, ka hoʻomaʻemaʻe ʻana i ka ea, nā mea lawe catalyst, ka hoʻihoʻi ʻana i ka solvent, etc. adsorption nui. ʻO nā huahana a pau o ke kūlana kiʻekiʻe a me ke kumukūʻai kūpono, i makemake nui ʻia e nā mea hoʻohana kūloko a me nā haole.

Me ka hoʻomaikaʻi lohi o ka hoʻomaopopo ʻana i ka mālama ʻana i ka wai a me ka mālama ʻana i ke kaiaola ʻike i ka honua, hoʻohana nui ʻia nā huahana kalapona i hoʻohana ʻia. ʻOiai ʻo Datong kahi ʻoihana hoʻoheheʻe hohonu hohonu, kūʻai nui ʻia nā huahana HNAC i Iapana, South Korea, ʻEulopa, ʻAmelika Hui Pū ʻIa a me nā ʻāina hoʻomohala ʻē aʻe. I ka manawa like, ke piʻi aʻe nei nā koi o ka mākeke kūloko. He ākea a hoʻohana nui ʻia ka wahi hoʻomohala o ka huahana i ka mālama ʻana i ka wai, ka ʻaila, kemika, lāʻau lapaʻau, meaʻai, brewing, textiles paʻi a hoʻoluʻu, ʻoihana māmā, ʻoihana koa, palekana kaiapuni, mana uila a me nā ʻoihana ʻē aʻe.

Lawe ʻo HNAC i ka "hoʻokele maikaʻi, hana ikaika, hoʻomohala coentinuous" e like me ka manao uhane, a "mea kūʻai mua, maikaʻi mua" ma ke ʻano he kumu ʻoihana. Hoʻokipa maikaʻi mākou i nā mea kūʻai ma ka home a ma waho i kā mākou hui e kipa a kūkākūkā i ka ʻoihana.
