ʻO ke koena maloʻo o ka aila ua māhā a hoʻopaʻa ʻia ma 500-550 ℃ i loko o ka ʻāpana coking e hana i ka coke paʻa ʻeleʻele.Manaʻo nui ʻia he kalapona amorphous, a i ʻole kahi carbide polymer aromatic i loaʻa i ka nila e like me a i ʻole ke ʻano o ka micro graphite crystals.He kiʻekiʻe loa ka ratio hydrocarbon, 18-24.He 0.9-1.1 ka nui o ka lehu, a he 0.1% - 1.2% ka lehu, a he 3% - 16%.

I ka makahiki 2021, he 30.295 miliona ka nui o ka aila coke o Kina, me ka ulu ana o ka makahiki he 3.7%;ʻO ka koi ʻike ʻia no ka coke petroleum ma Kina he 41.172 miliona tons, ʻoi aku ka 9.2% makahiki ma ka makahiki.

Ka puka a me ka koi ʻana o ka petroleum coke ma Kina mai 2016 a 2021.

Hōʻike pili: Hōʻike noiʻi e pili ana i ka Dynamic Analysis and Investment Potential of China's Petroleum Coke Industry ma 2022-2028 i hoʻopuka ʻia e Smart Research Consulting

I ka wā mua, ʻo ke kaʻina hana coking no ka hana ʻana i ka coke petroleum ma ka home a ma waho ʻo ke kettle coking a i ʻole open heart coking.I kēia manawa, hoʻohana nui ʻia ka coking lohi.I ka makahiki 2021, ʻo ka nui loa o ka ʻaila coke ma Kina he 11.496 miliona tons ma Shandong;ʻO 3.238 miliona tons ka puka ʻana o ka petroleum coke ma Liaoning

Wahi a ka ʻikepili kuʻuna Kina, ʻo ka lawe ʻana mai o ka ʻaila coke mai Kina he 12.74 miliona tons ma 2021, ʻoi aku ka 24% o ka makahiki ma ka makahiki;ʻO ka nui o ka hoʻokuʻu ʻana he 1.863 miliona tons, ʻoi aku ka 4.4% makahiki ma ka makahiki.I ka makahiki 2021, he 2487.46 miliona US ka nui o ka lawe ʻia mai o ka aila coke o Kina, a he 876.47 miliona mau kālā ʻAmelika.

ʻAʻole pili wale nā ​​waiwai o ka petroleum coke i nā mea maka, akā pili pū kekahi i ke kaʻina coking lohi.I ka makahiki 2021, e emi iho ana ka nui o ka hana o ka petroleum coke o Kina i 64.85%

Hiki ke hoʻohana ʻia ka Petroleum coke i ka graphite, smelting a me nā ʻoihana kemika ma muli o kona ʻano.E piʻi ke kumukūʻai ma 2022, a e emi iho i Iune.I ʻAukake 2022, ʻo ke kumu kūʻai o ka ʻaila coke o Kina e kokoke ana i 4107.5 yuan/ton.
