Ka nānā ʻana o CPC ma kā mākou hale hana

ʻO ke kahua noi nui o ka coke calcined ma Kina ka ʻoihana alumini electrolytic, e helu ana ma mua o 65% o ka nui o ka coke calcined, ukali ʻia e ke kalapona, silicon ʻoihana a me nā ʻoihana hoʻoheheʻe ʻē aʻe. ʻO ka hoʻohana ʻana i ka coke calcined ma ke ʻano he wahie ma ka sima, ka hana mana, ke aniani a me nā ʻoihana ʻē aʻe, e helu ana i kahi hapa liʻiliʻi.

I kēia manawa, ua like like ka lako kūloko a me ke koi o ka coke calcined. Eia nō naʻe, ma muli o ka hoʻokuʻu aku i ka nui o ka coke petroleum kiʻekiʻe haʻahaʻa-sulfur, ʻaʻole lawa ka lako kūloko o ka coke calcined, a pono nō hoʻi e lawe mai i ka coke calcined medium a me high sulfur no ka hoʻopihapiha.

Me ke kūkulu ʻia ʻana o ka nui o nā ʻāpana coking i nā makahiki i hala iho nei, e hoʻonui ʻia ka hana o ka coke calcined ma Kina.

Ma muli o ka nui o ka sulfur, hiki ke puʻunaue ʻia i ka coke sulfur kiʻekiʻe (ʻoi aku ka nui o ka sulfur ma mua o 3%) a me ka coke sulfur haʻahaʻa (ʻoi aku ka nui o ka sulfur ma lalo o 3%).

Hiki ke hoʻohana ʻia ka coke sulfur haʻahaʻa e like me ka hoʻopili anodic a me ka anode i hoʻomoʻa mua ʻia no ka mea kanu alumini a me ka electrode graphite no ka mea kanu kila.

Hiki ke hoʻohana ʻia ka coke sulfur haʻahaʻa kiʻekiʻe (ʻoi aku ka liʻiliʻi o ka sulfur ma mua o 0.5%) e hana i ka electrode graphite a me ka mea hoʻohuihui carbonizing.

Hoʻohana pinepine ʻia ka coke sulfur haʻahaʻa o ke ʻano maʻamau (ʻoi aku ka nui o ka sulfur ma mua o 1.5%) i ka hana ʻana o nā anodes i hoʻomoʻa mua ʻia.

Hoʻohana nui ʻia ka petroleum coke haʻahaʻa ke ʻano i ka hoʻoheheʻe ʻana i ka silicon ʻoihana a me ka hana ʻana i ka hana anodic paste.

Hoʻohana pinepine ʻia ka coke kiʻekiʻe-sulfur e like me ka wahie i nā hale hana sima a me nā hale hana mana.
