ʻO ke kaulahao ʻoihana ʻAkaʻakika Adipic
ʻO kaʻakika Adipic he waikawa dicarboxylicʻoihana nui, hiki ke hana i nāʻano likeʻole, e like me ka hoʻokumuʻana i ka paʻakai, esterification, amidation, a me nā mea'ē aʻe. He kuleana koʻikoʻi i ka hana kemika, ʻoihana synthesis organik, lāʻau lapaʻau, hana lubricant, etc. butadiene, cyclohexane a me cyclohexene. I kēia manawa, ua hoʻopau nui ʻia ke kaʻina hana phenol, a aia nō ke kaʻina hana butadiene i ka pae noiʻi. I kēia manawa, hoʻomalu ʻia ka ʻoihana e nā kaʻina hana cyclohexane a me cyclohexene, me benzene, hydrogen a me nitric acid ma ke ʻano he kumu.

ʻO ke kūlana ʻoihana ʻona Adipic
Mai ka ʻaoʻao hoʻolako o ka ʻakika adipic home, ke ulu mālie nei ka mana hana o ka adipic acid ma Kina a ke piʻi mālie nei ka huahana i kēlā me kēia makahiki. Wahi a nā helu helu, i ka makahiki 2021, ʻo 2.796 miliona ka nui o ka waikawa adipic / makahiki, ʻo ka hana adipic acid he 1.89 miliona tons, kahi hoʻonui o 21.53% makahiki-ma-makahiki, a ʻo ka nui o ka hoʻololi ʻana he 67.60%.

Mai ka ʻaoʻao koi, piʻi mau ka hoʻohana ʻana o ka adipic acid i kahi haʻahaʻa haʻahaʻa haʻahaʻa i kēlā me kēia makahiki mai 2017-2020. Wahi a nā helu helu, i ka makahiki 2021, hoʻihoʻi hou ka noi o lalo no ka hoʻopili ʻana i ka PU a ulu wikiwiki ka hoʻohana ʻana i ka waikawa adipic, me ka hoʻohana ʻana i ka makahiki he 1.52 miliona tons, ʻoi aku ka 30.08% o ka makahiki.

Mai ka hale o ka home adipic acid koi, PU hoʻopili ʻoihana ʻoihana ma kahi o 38.20%, nā kāmaʻa maka ma kahi o 20.71% o ka nui o ka noi, a me ka nylon 66 mau helu no kahi 17.34%. A hoʻohana nui ʻia ka waikawa adipic honua e hana i ka paʻakai nylon 66.

ʻO ke kūlana lawe mai a hoʻokuʻu aku i ka ʻoihana adipic acid

Mai ke kūlana lawe mai a me ka hoʻokuʻu aku, ʻoi aku ka nui o ka hoʻokuʻu ʻana o Kina i waho o ka waika adipic ma mua o ka lawe ʻana mai, a ua piʻi ka nui o ka lawe ʻana aku i ka piʻi ʻana o ke kumukūʻai makeke adipic. Wahi a nā helu helu, i ka makahiki 2021, ʻo ka nui o ka hoʻokuʻu ʻana o ka adipic acid ma Kina he 398,100 tons, a ʻo ka nui o ka hoʻoiho ʻana he $ 600 miliona.

Mai ka hāʻawi ʻana i nā wahi e hoʻokuʻu aku ai, ʻo ʻAsia a me ʻEulopa ka huina o 97.7% o nā hoʻoiho. ʻO nā luna ʻekolu ʻo Turkey me 14.0%, Singapore me 12.9% a me Netherlands me 11.3%.

Ke kumu hoʻokūkū o ka ʻoihana ʻakika adipic

Ma ke ʻano o ka hoʻokūkū hoʻokūkū mākeke (ma ka hiki), ʻoi aku ka paʻa o ka mana hana adipic acid home, me nā mea hana ʻelima adipic acid kiʻekiʻe he 71% o ka nui o ka mana hana o ka ʻāina. Wahi a nā helu helu, ʻo ke kūlana CR5 o ka waikawa adipic ma Kina i 2021: Huafeng Chemical (750,000 tons, helu no 26.82%), Shenma Nylon (475,000 tons, helu no 16.99%), Hualu Hensheng (326,000 tons, accounting for 326,000 tons, accounting for 11.6%). ), Jiangsu Haili (300,000 tons, helu no 10.73%), Shandong Haili (225,000 tons, helu no 8.05%).

ʻO ke ʻano hoʻomohala e hiki mai ana o ka ʻoihana adipic acid

1. Aia ka ʻokoʻa kumu kūʻai i kahi pōʻai piʻi

I ka makahiki 2021, ua hōʻike ʻia ke kumukūʻai o ka adipic acid i ka piʻi ʻana o ka piʻi ʻana ma muli o ka piʻi ʻana o ke kumu kūʻai o lalo, a ma Pepeluali 5, 2022, ʻo ke kumu kūʻai o ka adipic acid he 13,650 yuan/ton, aia ma kahi kiʻekiʻe o ka mōʻaukala. Ma muli o ka piʻi ʻana o ke kumukūʻai o benzene maʻemaʻe, ua hāʻule ka laha adipic acid i kahi haʻahaʻa haʻahaʻa i ka hapa mua o 2021, a mai ʻOkakopa 2021, ua hāʻule nā ​​kumukūʻai maka a ua hoʻonui ʻia ka laha adipic acid. ʻO ka laha adipic acid he RMB5,373/ton ma Pepeluali 5, 2022, ʻoi aku ka kiʻekiʻe ma mua o ka awelika mōʻaukala.

2.PBAT a me ka nylon 66 hana e hoʻoulu i ka noi

Me ka hoʻolaha ʻana o ka paʻa ʻana i ka plastic, ka ulu ʻana o ka PBAT i ka home, ʻoi aku ka nui o nā papahana i kūkulu ʻia; Eia kekahi, ʻo ka localization o adiponitrile e hoʻonā i ka pilikia o ka nylon 66 raw material neck, ma lalo o ke kūkulu ʻana a me ka hoʻolālā ʻana i ka mana adiponitrile ʻoi aku ma mua o 1 miliona tons, ʻo ka hoʻokuʻu ʻana i ka mana adiponitrile home e hoʻolalelale i ka nylon home 66 i hoʻomaka i kahi manawa o ka ulu wikiwiki. i ka hiki, e hoʻokomo ka adipic acid i kahi pōʻai hou o ka ulu koi.

I kēia manawa ke kūkulu ʻia nei a me ka hoʻolālā ʻana i ka mana o ka PBAT ma mua o 10 miliona mau tons, kahi o 4.32 miliona mau tons e manaʻo ʻia e hoʻokomo ʻia i ka hana ma 2022 a me 2023, hoʻokahi ton o PBAT e hoʻopau i kahi 0.39 tons o ka adipic acid, e hana ana i kahi koi no ka adipic acid o ma kahi o 1.68 miliona mau tona; ma lalo o ke kūkulu ʻana a me ka hoʻolālā ʻana i ka nylon 66 ka mana o 2.285 miliona tons, kahi ton o nylon 66 e hoʻopau i kahi 0.6 tons o ka adipic acid, e hana ana i kahi koi no ka adipic acid ma kahi o 1.37 miliona tons.
