Kūlana mākeke

ʻAno Hoʻolako a me ke Koi

Aia ka mākeke aniline honua i kahi pae o ka ulu mau. Ua manaʻo ʻia e hiki aku ka nui o ka mākeke aniline honua ma kahi o 8.5 biliona kālā US ma ka makahiki 2025, me ka nui o ka ulu makahiki hui (CAGR) e mālama ana ma kahi o 4.2%. Ua ʻoi aku ka nui o ka hana ʻana o ka aniline ma Kina ma mua o 1.2 miliona tons i kēlā me kēia makahiki, e helu ana no kahi kokoke i 40% o ka nui o ka hana ʻana o ka honua, a e hoʻomau i ka mālama ʻana i ka nui o ka ulu makahiki ma mua o 5% i nā makahiki ʻekolu e hiki mai ana. Ma waena o nā koi ma lalo no ka aniline, ʻo ka ʻoihana MDI (Methylene Diphenyl Diisocyanate) e helu ana i ka 70%-80%. I ka makahiki 2024, ua hiki aku ka nui o ka hana ʻana o ka MDI kūloko o Kina i 4.8 miliona tons, a ua manaʻo ʻia e ulu ka noi ma ka nui o ka makahiki o 6%-8% i nā makahiki ʻelima e hiki mai ana, e hoʻokele pololei ana i ka piʻi ʻana o ke koi aniline.

ʻAno Kūʻai

Mai ka makahiki 2023 a i ka makahiki 2024, ua loli ke kumukūʻai o ka aniline honua ma waena o 1,800-2,300 kālā ʻAmelika no ke tona. Manaʻo ʻia e paʻa ke kumukūʻai i ka makahiki 2025, e waiho ana ma kahi o 2,000 kālā ʻAmelika no ke tona. Ma ke ʻano o ka mākeke kūloko, ma ʻOkakopa 10, 2025, ʻo ke kumukūʻai o ka aniline ma Kina Hikina he 8,030 yuan no ke tona, a ma ka Panalāʻau ʻo Shandong, he 7,850 yuan no ke tona, e piʻi ana ma 100 yuan no ke tona i hoʻohālikelike ʻia me ka lā ma mua. Ua manaʻo ʻia e loli ke kumukūʻai makahiki awelika o ka aniline ma kahi o 8,000-10,500 yuan no ke tona, me ka emi ʻana o ka makahiki ma kahi o 3%.

Kūlana Hoʻokomo Mai a Hoʻokuʻu Aku

Nā Kaʻina Hana Hana Maʻemaʻe

Ua hoʻolaha nā ʻoihana alakaʻi i ka ʻoihana, e like me BASF, Wanhua Chemical, a me Yangnong Chemical, i ka ulu ʻana o nā kaʻina hana aniline i nā kuhikuhi maʻemaʻe a haʻahaʻa-kalapona ma o ka hoʻonui ʻenehana a me ka hoʻonohonoho kaulahao ʻoihana i hoʻohui ʻia. No ka laʻana, ʻo ka hoʻohana ʻana i ke ʻano hydrogenation nitrobenzene e pani i ke ʻano hōʻemi pauka hao kuʻuna ua hōʻemi maikaʻi i ka hoʻokuʻu ʻia ʻana o "ʻekolu ʻōpala" (kinoea ʻōpala, wai ʻōpala, a me ka ʻōpala paʻa).

Hoʻololi Mea Maka

Ua hoʻomaka kekahi mau ʻoihana alakaʻi e hoʻolaha i ka hoʻohana ʻana i nā mea maka biomass e pani i kahi hapa o nā mea maka fossil. ʻAʻole wale kēia e kōkua i ka hoʻomaikaʻi ʻana i ka maikaʻi o ka huahana akā e hōʻemi maikaʻi hoʻi i nā kumukūʻai hana.
