Cov kua tsis muaj xim pob tshab. Nws yog ib qho azeotrope ntawm dej distilled ntawm 78.01 ° C. Nws yog volatile. Nws tuaj yeem sib xyaw nrog dej, glycerol, trichloromethane, benzene, ether thiab lwm yam organic solvents. Cov tshuaj excipients, cov kuab tshuaj. Cov khoom no yog cov kua tsis muaj xim clarified; Me ntsis ntxiv tsw; Volatile, yooj yim rau hlawv, hlawv lub teeb xiav nplaim; Npau kom txog li 78 ° C. Cov khoom no tuaj yeem sib xyaw nrog dej, glycerin, methane lossis ethyl qab zib.

Muaj ntau cov phiaj xwm roj pob kws uas tau npaj thiab tsim tsa hauv Suav teb, thiab lawv qhov kev faib tawm yog qhov tseeb cuam tshuam nrog cov khoom siv pob kws. Qhov chaw tsim kho tseem ceeb ntawm roj pob kws hauv Suav teb tseem nyob hauv thaj chaw tsim cov pob kws tseem ceeb hauv Northeast Suav teb thiab Anhui, thaum cov khoom siv raw xaiv rau cov phiaj xwm npaj thiab tsim tsa hauv thaj chaw uas muaj huab cua kub thiab noo xws li Southwest, South China, Southeast thiab Southeast Asian lub teb chaws feem ntau yog cassava, sugarcaw thiab lwm yam qoob loo kub. Tsis tas li ntawd, roj ethanol kuj tseem tuaj yeem tsim tsa hauv Shaanxi, Hebei thiab lwm thaj chaw uas muaj cov thee ntau, thiab cov phiaj xwm no feem ntau yog thee-rau-ethanol. Raws li cov ntaub ntawv txheeb cais, txij li xyoo 2022, Tuam Tshoj cov roj pob kws tsim tawm yog li 2.23 lab tons, thiab tus nqi tso tawm yog li 25.333 billion yuan.

Hais txog kev siv tshuab tsim khoom, peb ntawm thawj pawg ntawm cov tuam txhab roj ethanol uas tau tsim hauv Suav teb siv cov txheej txheem ntub. Txij thaum ntawd los, cov tuam txhab uas tau tsim khoom feem ntau yog ua raws li cov txheej txheem qhuav, txog yim, nrog rau kev hloov pauv tas mus li ntawm cov qauv txheej txheem tsim khoom, cov txheej txheem ntub tau txhawb nqa sai dua. Hauv Suav teb, cov roj pob kws ethanol feem ntau faib rau sab qaum teb sab hnub tuaj ntawm Suav teb (suav nrog sab qaum teb sab hnub tuaj ntawm Inner Mongolia), xeev Anhui thiab xeev Henan, qhov twg cov pob kws tsim khoom ntau.

Thaum Lub Kaum Ib Hlis 15, cov lus hais ntawm qee lub tuam txhab tsim khoom ethanol hauv tsev tau ruaj khov
Jiangsu Dongcheng Biotechnology 150,000 tons/xyoo lub Hoobkas ua ethanol cassava qib kaw lawm, tus nqi sab nraud ntawm qib lag luam yog 6800 yuan/ton. Henan Hanyong muaj 300,000 tons/xyoo cov kab tsim khoom ethanol, tus nqi zoo heev yog 6700 yuan/ton, tus nqi anhydrous yog 7650 yuan/ton suav nrog se. Shandong Chengguang Industry and Trade Co., LTD. 50,000 tons/xyoo lub Hoobkas ua ethanol ua haujlwm ib txwm, 95% ethanol sab nraud tus nqi yog 06900 yuan/ton, tus nqi sab nraud ntawm anhydrous yog 7750 yuan/ton.
