ʻO ka wai ʻākala kala ʻole. He azeotrope ia o ka wai i hoʻoheheʻe ʻia ma 78.01 ° C. Hiki ke hoʻopili ʻia me ka wai, glycerol, trichloromethane, benzene, ether a me nā mea hoʻoheheʻe organik. Nā mea kōkua lāʻau lapaʻau, solvents. He wai hoʻomaʻemaʻe kala ʻole kēia huahana; ʻAiʻala iki; Hiki ke puhi ʻia, maʻalahi ke puhi ʻana, e ʻā ana ka lapalapa uliuli māmā; E hoʻolapalapa i kahi 78 ° C. Hiki ke hoʻopili ʻia kēia huahana me ka wai, glycerin, methane a i ʻole ethyl sugar.

Hoʻolālā ʻia a kūkulu ʻia ka nui o nā pāhana ethanol wahie kulina ma Kina, a ʻike maopopo ʻia kā lākou hāʻawi spatial i pili i nā kumu kumu kulina. ʻO ka wahi hana nui o ka ethanol wahie kulina ma Kina, aia nō ia ma nā wahi hana kulina nui ma Northeast Kina a me Anhui, aʻo nā mea maka i koho ʻia no nā papahana i hoʻolālā ʻia a kūkulu ʻia i nā wahi me ke anuanu kiʻekiʻe a me ke anuanu e like me Southwest, South China, ʻO nā ʻāina Hikina Hema a me ʻAsia Hikina Hema ka nui o ka cassava, ke kō a me nā mea kanu wela ʻē aʻe. Eia kekahi, hiki ke kūkulu ʻia ka wahie ethanol ma Shaanxi, Hebei a me nā wahi ʻē aʻe me ka hana lanahu kiʻekiʻe, a ʻo kēia mau papahana ka nui o ka lanahu-to-ethanol. Wahi a nā helu helu, e like me 2022, ʻo ka hana ʻana o ka wahie ethanol o Kina ma kahi o 2.23 miliona tons, a ʻo ka waiwai hoʻopuka ma kahi o 25.333 biliona yuan.

Ma ke ʻano o ka ʻenehana hana, ʻekolu o ka hui mua o nā ʻoihana ethanol wahie i hoʻokomo ʻia i loko o ka hana ʻana ma Kina e hoʻohana i ke kaʻina wai. Mai ia manawa, hoʻokumu nui ʻia nā ʻoihana i ke kaʻina hana maloʻo, a hiki i ka ʻewalu, me ka hoʻololi mau ʻana o ke kaʻina hana hiki ke hana, ʻoi aku ka wikiwiki o ke kaʻina hana. Ma Kina, hoʻolaha nui ʻia ka ethanol wahie kulina ma ka ʻākau hikina o Kina (me ka ʻākau hikina o Inner Mongolia), ka ʻāina ʻo Anhui a me ka ʻāina ʻo Henan, kahi i kiʻekiʻe ai ka hana kulina.

Ma ka lā 15 o Nowemapa, ua kūpaʻa ka ʻōlelo a kekahi mau mea hana ethanol home
ʻO Jiangsu Dongcheng Biotechnology 150,000 tons/year cassava grade ethanol plant i pani ʻia, ʻoihana ma waho o ka ʻōlelo ʻōlelo 6800 yuan/ton. Henan Hanyong 300,000 tons / makahiki ethanol mea kanu laina hana, ke kumu kūʻai maikaʻi loa o 6700 yuan / ton, anhydrous kumu kūʻai o 7650 yuan / ton me ka hale hana ʻauhau. Shandong Chengguang Industry and Trade Co., LTD. 50,000 tons/makahiki ethanol mea kanu hana maʻamau, 95% ethanol waho quotation 06900 yuan/ton, anhydrous waho kuhikuhi 7750 yuan/ton.
