A. ka hoʻokaʻawale ʻana o ka petroleum coke
ʻO ka distillation o ka ʻaila maka, ʻo ia ka hoʻokaʻawale ʻana o ka ʻaila māmā a me ke kaumaha, a laila ma o ke kaʻina hana o ka haki wela ʻana o ka ʻaila kaumaha, hoʻololi ʻia i nā huahana, mai ke ʻano, ʻo Coke no ke ʻano ʻokoʻa, ka nui o ka poloka ʻeleʻele (a i ʻole nā mea liʻiliʻi), ka luster metala, nā ʻāpana Coke me ka ʻano porous, ʻo ke kumu nui o ke kalapona, Paʻa 80wt%. (wt = kaumaha)
Wahi a ke ʻano hanahiki ke māhele ʻia i lokokōka makaa mekōka i moʻa ʻiaLoaʻa ka mea mua e ka hale kiaʻi coke o ka mea hana coking lohi, i ʻike ʻia hoʻi ʻokōka mua; Hoʻopuka ʻia ka mea hope e ka calcination (1300°C), i ʻike ʻia hoʻi ʻokōke i hoʻomoʻa ʻia.
Wahi a ka nui o ka sulfur, hiki ke māhele ʻia i lokocoke sulfur kiʻekiʻe(ʻoi aku ka nui o ka sulfur ma mua o4%), coke sulfur waena(ʻo ka nui o ka sulfur2%-4%) a mecoke sulfur haʻahaʻa(ʻoi aku ka liʻiliʻi o ka nui o ka sulfur ma mua o2%).
Wahi a nā ʻano microstructure like ʻole, hiki ke māhele ʻia i lokokōka huʻaa mekoka nilaʻO ka porous mua e like me ka spongy, i ʻike ʻia hoʻi ʻokōke maʻamauʻO ka mea hope loa he paʻa e like me ka fibrous, i ʻike ʻia hoʻi ʻokōke kiʻekiʻe.
Ma muli o nā ʻano like ʻolehiki ke māhele ʻia i lokokoka nila, kōkō pana or kōka poepoe, kōka huʻa, pauka kōkaʻehā ʻano.
B. ka hoʻopuka ʻana o ka petroleum coke
ʻO ka hapa nui o ka petroleum coke i hana ʻia ma Kina no ka low sulfur coke, ka mea i hoʻohana nui ʻia mahoʻoheheʻe ʻana i ka aluminia meka hana ʻana i ka graphite.Hoʻohana nui ʻia ka mea ʻē aʻe nonā huahana kalapona, e like meʻeleka graphite, ʻāʻī anode, hoʻohana ʻia nokila, nā metala hao ʻole; Nā huahana silicon kalapona, e like me nā ʻano like ʻolenā huila wili, one,pepa one, a pēlā aku; ʻO ka calcium carbide kalepa no ka hana ʻana i nā fiber synthetic, acetylene a me nā huahana ʻē aʻe; Hiki ke hoʻohana ʻia ma ke ʻano he wahie, akā i ka wā e hana ai i ka wahie, pono e hoʻohana i ka wili hopena graded e hana i ka wili ultrafine. Ma hope o ka hana ʻana i ka pauka coke ma o nā lako, hiki ke puhi ʻia. Hoʻohana nui ʻia ka pauka coke ma ke ʻano he wahie ma kekahi mau hale hana aniani a me nā hale hana slurry wai lanahu.
Wahi a ka National Bureau of Statistics, ʻo ka hana ʻana o ka petroleum coke a Kina i ka makahiki 2020 he 29.202 miliona tons, i piʻi aʻe he 4.15% i kēlā me kēia makahiki, a mai Ianuali a ʻApelila 2021, ʻo ka hana ʻana o ka petroleum coke a Kina he 9.85 miliona tons.
ʻO ka hana ʻana o ka petroleum coke ma Kina, ua kau nui ʻia ma ka hikina o Kina, ka hikina ʻākau o Kina a me ka Hema o Kina, me ka hana kiʻekiʻe loa ma ka hikina o Kina. Ma ka ʻāina hikina holoʻokoʻa o Kina, ʻo Shandong ka panalāʻau i loaʻa ka hana kiʻekiʻe loa o ka petroleum coke, i hōʻea i 10.687 miliona tone i ka makahiki 2020. ʻO ka hana ʻana o ka petroleum coke ma ka panalāʻau ʻo Shandong ʻaʻole wale ke kūlana mua ma ka hikina o Kina, akā ke kūlana mua hoʻi ma nā panalāʻau a me nā kūlanakauhale āpau ma Kina, a ʻoi aku ka maikaʻi o ka hana ʻana o ka petroleum coke ma mua o nā panalāʻau a me nā kūlanakauhale ʻē aʻe.
C. Ka lawe ʻana mai a me ka hoʻokuʻu aku ʻana i ka coke petroleum
ʻO Kina kekahi o nā mea lawe nui mai o ka petroleum coke, nona ka hapa nui mai ʻAmelika Hui Pū ʻIa, Saudi Arabia a me Rusia. Wahi a ka ʻikepili o nā Customs o Kina, ua hōʻike ka nui o ka lawe ʻana mai o ka petroleum coke ma Kina mai 2015 a 2020 i kahi ʻano piʻi holoʻokoʻa. I ka makahiki 2019, ʻo ka nui o ka lawe ʻana mai o ka petroleum coke ma Kina he 8.267 miliona tone, a i ka makahiki 2020, he 10.277 miliona tone, he piʻi ʻana o 24.31% i hoʻohālikelike ʻia me 2019.
I ka makahiki 2020, ʻo ka nui o ka lawe ʻana mai o ka Petroleum coke ma Kina he USD 1.002 biliona, i emi iho he 36.66% i kēlā me kēia makahiki. I ka makahiki 2020, ua hōʻea ka nui o ka lawe ʻana mai o ka petroleum coke i kona kiʻekiʻe loa, akā ua emi iho ka waiwai o ka lawe ʻana mai o ka petroleum coke. I ka wā i hoʻopilikia nui ʻia ai ka hoʻokele waiwai honua e ka maʻi ahulau COVID-19, ua hāʻule pū ke kumukūʻai o ka petroleum coke ma ka mākeke honua, ka mea i hoʻoulu i ka lawe ʻana mai o ka petroleum coke ma Kina a hoʻonui i ka nui o ka lawe ʻana mai o ka petroleum coke, akā ua hoʻemi i ka nui o ka lawe ʻana mai.
Wahi a ka ʻikepili o nā Customs Kina, ua hōʻike ka hoʻokuʻu ʻana aku o ka petroleum coke mai Kina i kahi ʻano emi, ʻoiai ma 2020 ma muli o ka hopena o COVID-19, ua emi nui ka hoʻokuʻu ʻana aku o ka petroleum coke mai Kina, i ka makahiki 2020, ua emi ka hoʻokuʻu ʻana aku o ka petroleum coke mai Kina i 1.784 miliona DOLAR, he emi makahiki o 22.13%; ʻO ke kumukūʻai o nā hoʻokuʻu aku he $459 miliona, i lalo he 38.8% makahiki ma ka makahiki.
D. Ke ʻano hoʻomohala o ka ʻoihana coke petroleum
I ka wā lōʻihi, ua piha mau ka mākeke petroleum coke i nā mea kānalua he nui, a ke kū nei ke ʻano o ka lako a me ke koi o ka petroleum coke i nā pilikia hou aʻe. Mai ka manaʻo o ka hoʻonohonoho mana, i ka wā pōkole, ma muli o ka lohi o ka lawe ʻana o ka mana hydrogenation aila koena, ʻo ka hoʻouna lohi ʻana i nā mea hana coking ke kuhikuhi nui. I ka wā lōʻihi, e kaupalena ʻia ka ʻaoʻao lako o ka petroleum coke e ka palekana kaiapuni, nā kulekele a me nā mea ʻē aʻe, a e hoʻomau ʻia nā ʻenehana hou a me nā pani ʻoi aku ka aloha i ke kaiapuni. Ke lilo mālie nei ke kulekele palekana kaiapuni i mea maʻamau, a ʻaʻole hiki ke kaupalena ʻia ka hana ʻana e hoʻokō i nā hoʻokuʻu haʻahaʻa loa. Me ka hoʻomaikaʻi ʻana o nā mea palekana kaiapuni ponoʻī o nā ʻoihana, e hoʻonāwaliwali ʻia ka hopena o ke kulekele palekana kaiapuni ma ka mākeke, a e hoʻonui ʻia ka mana o ka pilina mākeke a me ke koi a me ke kumukūʻai kūʻai mea maka o nā ʻoihana.
Ma ka ʻaoʻao koi, e hoʻomau ka ʻoihana petroleum coke i nā pilikia hoʻokele waiwai like ʻole, nā kumu kulekele, nā ʻoihana alumini electrolytic i kēia manawa i kau ʻia ma luna o ka alumina, ke kumukūʻai uila, ke kiʻekiʻe o ke kumukūʻai e loaʻa ai ka waiwai e ʻōlelo ai, no laila e loaʻa i nā ʻoihana alumini e hiki mai ana kahi kaulahao ʻoihana piha i loaʻa ka waiwai nui, ʻoiai e loli mālie ka hoʻolālā mākeke alumini, e hoʻoili mālie i ka hiki i ke kikowaena. , E hoʻopilikia ia i ke ʻano a me ka hoʻomohala ʻana o ka mākeke anode pre-baked a me ka mākeke kalapona i ka wā e hiki mai ana.
I ka wā waena a me ka lōʻihi, ʻo ke kaiapuni macroeconomic, nā kulekele ʻoihana aupuni, ke ʻano hoʻolako huahana, nā loli waihona, nā kumukūʻai mea maka, ka hoʻopau ʻana ma hope, nā pilikia, a me nā mea ʻē aʻe, e lilo paha i mau kumu alakaʻi e hoʻopilikia ana i ka mākeke coke aila ma nā pae like ʻole. No laila, pono nā ʻoihana e kālailai i ke kūlana o ka ʻoihana coke petroleum, e aʻo hou e pili ana i nā kulekele pili ma ka home a ma waho, e wānana i ke kuhikuhi hoʻomohala e hiki mai ana o ka mākeke coke petroleum, e pale i nā pilikia i ka manawa kūpono, e hopu i nā manawa kūpono, nā loli a me ka hana hou i ka manawa kūpono, he hopena lōʻihi ia.
