Hana ʻia ʻo Acrylonitrile e ka hoʻohana ʻana i ka propylene a me ka amonia ma ke ʻano he kumu waiwai, ma o ka hopena oxidation a me ka hana hoʻomaʻemaʻe. He mea hoʻohuihui ia me ke kumu kemika C3H3N, he wai kala ʻole me ka ʻala hoʻonāukiuki, hiki ke puhi ʻia, hiki i kona mahu a me ka ea ke hana i kahi hui pahū, a he maʻalahi ke kumu o ka puhi ʻana ke ʻike ʻia i ka lapalapa a me ka wela wela, a hoʻokuʻu i ke kinoea ʻawaʻawa, a hana ikaika me nā oxidizers, nā waikawa ikaika, nā kumu bromine, nā amine ikaika.

Hoʻohana nui ʻia ia e like me ka mea maka no ka acrylic a me ABS / SAN resin, a hoʻohana nui ʻia i ka hana ʻana o ka acrylamide, paste a adiponitrile, synthetic rubber, Latex, etc.

Nā noi ʻana o ka mākeke Acrylonitrile

He mea koʻikoʻi ka Acrylonitrile no ʻekolu mau mea synthetic nui (plastic, rubber synthetic a me nā fibers synthetic), a ʻo ka hoʻohana ʻana i lalo o ka acrylonitrile ma Kina i hoʻopaʻa ʻia i ABS, acrylic a me acrylamide, ʻoi aku ka nui ma mua o 80% o ka nui o ka ʻai ʻana o ka acrylonitrile. I nā makahiki i hala iho nei, ua lilo ʻo Kina i hoʻokahi o nā ʻāina e ulu wikiwiki ana i ka mākeke acrylonitrile honua me ka hoʻomohala ʻana o nā mea hana home a me nā ʻoihana kaʻa. Hoʻohana nui ʻia nā huahana o lalo i nā ʻano like ʻole o ka hoʻokele waiwai o ka ʻāina, e like me nā mea hana hale, nā lole, nā kaʻa, a me nā lāʻau lapaʻau.

Hana ʻia ʻo Acrylonitrile mai propylene a me ammonia e ka hopena oxidation a me ke kaʻina hana hoʻomaʻemaʻe, a hoʻohana nui ʻia i ka resin, ka hana ʻenehana acrylic, a me ka carbon fiber nā wahi noi me ka wikiwiki e ulu nei i ka wā e hiki mai ana.

ʻO ka carbon fiber, ʻo ia kekahi o nā hoʻohana koʻikoʻi i lalo o ka acrylonitrile, he mea hou i kēia manawa e pili ana i ka noiʻi a me ka hoʻomohala ʻana a me ka hana ʻana ma Kina. Ua lilo ʻo Carbon fiber i lālā koʻikoʻi o nā mea māmā, a lawe mālie i nā mea metala mua, a ua lilo ia i mea noi kumu ma nā kahua kīwila a me ka pūʻali koa.

Ke hoʻomau nei ka hoʻokele waiwai o Kina i ka wikiwiki, ke hoʻomau nei ka piʻi ʻana o ke koi no ka fiber carbon a me kāna mau mea hana. Wahi a nā helu helu pili, ʻo ke koi no ka carbon fiber ma Kina a hiki i 48,800 tons i 2020, kahi piʻi o 29% ma mua o 2019.

Me ka hoʻomau mau ʻana o ka ʻepekema a me ka ʻenehana, hōʻike ka mākeke acrylonitrile i nā ʻano hoʻomohala nui.
ʻO ka mea mua, hoʻolaha ʻia ke ala o ka hana acrylonitrile me ka propane ma ke ʻano he meaʻai.
ʻO ka lua, ke hoʻomau nei ka noiʻi ʻana o nā catalysts hou i kumuhana noiʻi no nā loea kūloko a me nā haole.
ʻO ke kolu, ʻo ka nui o ka mea kanu.
ʻO ka hā, ka mālama ʻana i ka ikehu a me ka emi ʻana o ka hoʻokuʻu ʻana, ʻoi aku ka nui o ka hoʻoponopono ʻana i ka hana.
ʻO ka lima, ua lilo ka mālama ʻana i ka wai ʻino i mea noiʻi koʻikoʻi.

ʻO ka Acrylonitrile Nui Kapa Hana Hana

ʻO nā hale hana acrylonitrile kūloko o Kina ka mea nui i nā ʻoihana nona ka China Petroleum & Chemical Corporation (Sinopec) a me China National Petroleum Corporation (CNPC). Ma waena o lākou, ʻo ka nui o ka mana hana o Sinopec (me nā hui hui pū) he 860,000 tons, ʻo ia ka 34.8% o ka nui o ka mana hana; ʻO ka mana hana o PetroChina he 700,000 tons, e helu ana no 28.3% o ka nui o ka mana hana; ʻO ka mana hana o nā ʻoihana pilikino ʻo Jiangsu Searborn Petrochemical, Shandong Haijiang Chemical Co. Ltd. me ka mana hana acrylonitrile o 520,000 tons, 130,000 tons a me 260,000 tons, e helu ana i ka nui o ka hiki ke hana ma kahi o 36.8%.

Mai ka hapa lua o 2021, ka lua o ka mahele o ZPMC me 260,000 tons / makahiki, ka lua o ka mahele o Kruel me 130,000 tons / makahiki, ka lua o ka mahele o Lihua Yi me 260,000 tons / makahiki a me ke kolu o ka mahele o Srbang me 260,000 tons / makahiki ua hiki i ka hana hou acrylonitrile. ʻO 910,000 tons / makahiki, a ua hiki i ka nui o ka acrylonitrile kūloko i ka 3.419 miliona tons / makahiki.

ʻAʻole pau ka hoʻonui ʻana i ka mana acrylonitrile ma aneʻi. Ua hoʻomaopopo ʻia ma 2022, e hoʻokomo ʻia kahi mea kanu acrylonitrile hou 260,000 / makahiki ma Kina Hikina, kahi kanu 130,000 tons / makahiki ma Guangdong a me kahi mea kanu 200,000 tons / makahiki ma Hainan. ʻAʻole i kaupalena ʻia ka mana hana hale hou i Kina Hikina, akā e puʻunaue ʻia ma kekahi mau ʻāpana o Kina, ʻoi aku ka hoʻokomo ʻana o ka mea kanu hou ma Hainan i mea kokoke loa nā huahana i nā mākeke Kina Hema a me Asia Hikina Hema, a he mea maʻalahi hoʻi ia e lawe aku ma ke kai.

ʻO ka hoʻonui nui ʻana i ka hana e lawe mai i kahi piʻi i ka hana. Hōʻike nā helu helu Jinlian ua hoʻomau ka hana acrylonitrile o Kina i nā kiʻekiʻe kiʻekiʻe ma 2021. Ma ka hopena o Dekemaba 2021, ʻoi aku ka nui o ka hana acrylonitrile home ma mua o 2.317 miliona tons, ʻoi aku ka 19% makahiki-ma-makahiki, ʻoiai ʻo ka ʻai makahiki ma kahi o 2.6 miliona tons, me nā hōʻailona mua o ka overcapacity.

Aʻoaʻo hoʻomohala e hiki mai ana o ka acrylonitrile

I ka makahiki 2021 i hala iho nei, ua ʻoi aku ka nui o nā mea hoʻopuka acrylonitrile ma mua o ka lawe ʻana mai no ka manawa mua. ʻO ka nui o ka lawe ʻana mai o nā huahana acrylonitrile i ka makahiki i hala he 203,800 tons, ma lalo o 33.55% mai ka makahiki i hala, aʻo ka lawe ʻana aku i 210,200 tons, he piʻi o 188.69% mai ka makahiki i hala.

ʻAʻole hiki ke hoʻokaʻawale ʻia kēia mai ka hoʻokuʻu ʻia ʻana o ka mana hana hou ma Kina a aia ka ʻoihana i kahi kūlana o ka hoʻololi ʻana mai ke koena paʻa i ke koena. Eia kekahi, ua kū kekahi mau ʻāpana ʻEulopa a me ʻAmelika i ka hapaha mua a me ka lua, i ka hopena o ka hāʻule koke ʻana o ka lako, ʻoiai ʻo nā ʻāpana ʻĀsia i loko o ke kaʻina mālama i hoʻolālā ʻia, a ʻoi aku ka haʻahaʻa o nā kumukūʻai Kina ma mua o nā kumukūʻai ʻo ʻAsia, ʻEulopa a me ʻAmelika, i kōkua i ka hoʻonui ʻana i ka acrylonitrile o Kina e hoʻonui, me Taiwan Province o Kina, kokoke i Korea, India a me Turkey.

Ua hui pū ʻia ka piʻi ʻana o ka nui o ka lawe ʻana aku me ka piʻi ʻana o ka nui o nā ʻāina e lawe aku ana. Ma mua, ua hoʻouna nui ʻia nā huahana acrylonitrile o Kina i South Korea a me India. 2021, me ka emi ʻana o ka lako o nā ʻāina ʻē, ua hoʻonui ʻia ka nui o ka acrylonitrile export a hoʻouna ʻia i ka mākeke ʻEulopa, e pili ana i ʻehiku mau ʻāina a me nā wahi e like me Turkey a me Belgium.

Ua wānana ʻia ʻoi aku ka nui o ka ulu ʻana o ka hana acrylonitrile ma Kina i nā makahiki 5 e hiki mai ana ma mua o ka ulu ʻana o ka noi o lalo, e emi hou ana ka lawe ʻana mai, ʻoiai e hoʻomau ka hoʻonui ʻana o nā mea kūʻai aku, a ke manaʻo ʻia nei ka hoʻokuʻu ʻana aku o ka acrylonitrile i Kina i kahi kiʻekiʻe o 300,000 tons i 2022, no laila e hōʻemi ana i ka mākeke Kina.

Ke kūʻai aku nei ʻo chemwin i ke ʻano kiʻekiʻe, haʻahaʻa haʻahaʻa acrylonitrile feedstock ma ka honua holoʻokoʻa
