Cov txheej txheem ntau lawm Ethanol

Nqe lus piav qhia luv:

Hauv kev lag luam, ethanol feem ntau yog tsim los ntawm cov txheej txheem fermentation txheej txheem lossis txheej txheem dej ncaj qha ethylene. Fermentation ethanol tau tsim los ntawm kev ua winemaking thiab tsuas yog cov txheej txheem kev lag luam los tsim cov ethanol rau lub sijhawm ntev.

Hauv kev lag luam, ethanol feem ntau yog tsim los ntawm cov txheej txheem fermentation txheej txheem lossis txheej txheem dej ncaj qha ethylene. Fermentation ethanol tau tsim los ntawm kev ua winemaking thiab tsuas yog cov txheej txheem kev lag luam los tsim cov ethanol rau lub sijhawm ntev. Cov ntaub ntawv raw ntawm txoj kev fermentation feem ntau suav nrog cov khoom nyoos cereal (nplej, pob kws, sorghum, mov, millet, oats, thiab lwm yam), cov khoom siv qos (qos yaj ywm, qos yaj ywm, qos yaj ywm, thiab lwm yam), thiab cov khoom qab zib (beet , qab zib qab zib, pov tseg cov suab thaj, sisal, thiab lwm yam.) Thiab cov khoom siv cellulose (ntoo chips, straw, thiab lwm yam).

Txoj kev ua ke
Kev tso dej ncaj qha ntawm ethylene yog cov tshuaj tiv thaiv ncaj qha ntawm ethylene nrog dej thaum muaj cua sov, siab thiab nyob ntawm qhov muaj cov catalyst los tsim ethanol:

CH2═CH2 + H-OH → C2H5OH (Cov tshuaj tiv thaiv tau ua hauv ob kauj ruam. Thawj kauj ruam yog tsim cov organic mercury sib xyaw hauv cov dej-tetrahydrofuran tov nrog ntsev ntsev xws li mercury acetate, thiab tom qab ntawd txo nws nrog sodium borohydride.) - Ethylene tuaj yeem nqa los ntawm roj av tawg cov pa hauv qhov loj, nrog tus nqi qis thiab tso zis ntau, uas tuaj yeem txuag tau zaub mov ntau, yog li nws txhim kho sai heev.

Nws kuj tseem tuaj yeem hloov pauv mus rau hauv syngas los ntawm kev lag luam tshuaj lom neeg, tsim tawm ncaj qha lossis tsim los ntawm kev tsim cov hydrogenation ntawm acetic acid.

Thib peb, tus qauv zoo

Raws li cov neeg siv khoom xav tau, chav tsim khoom ethanol tuaj yeem ncav cuag cov qauv tsim nyog (GB10343-2008 qib tshwj xeeb, qib siab dua, qib dav, GB18350-2013, GB678-2008) lossis lwm yam txheej txheem thoob ntiaj teb.

Plaub, cov lus hais

Lub tuam txhab tuaj yeem ua tiav txoj haujlwm tseem ceeb xws li cawv, tshuaj lom neeg, tshuaj, DDGS.

Lub "Cim Cim" hom tshuaj ntxhua khaub ncaws thiab cov khoom siv ntxiv muaj kev lag luam nyob hauv tsev ntau dua 40%. Hauv xyoo 2010-2013, lub tuam txhab tau tso npe ua ntej hauv tib lub lag luam rau plaub xyoos sib law liag.
