Ethanol ntau lawm txheej txheem
Ua ntej, cov khoom siv raw
Hauv kev lag luam, ethanol feem ntau yog tsim los ntawm cov hmoov txhuv nplej siab fermentation txheej txheem lossis cov txheej txheem ethylene ncaj qha hydration. Fermentation ethanol yog tsim los ntawm winemaking thiab yog tib txoj kev lag luam los tsim ethanol rau lub sijhawm ntev. Cov khoom siv raw ntawm txoj kev fermentation feem ntau suav nrog cov khoom siv cereal (nplej, pob kws, sorghum, mov, millet, oats, thiab lwm yam), qos yaj ywm raw cov ntaub ntawv (cassava, qos yaj ywm qab zib, qos yaj ywm, thiab lwm yam), thiab qab zib raw cov ntaub ntawv (beet. , qab zib cane, pov tseg molasses, sisal, thiab lwm yam) thiab cellulose raw cov ntaub ntawv (ntoo chips, straw, thiab lwm yam).
Qhov thib ob, txheej txheem
Cereal raw khoom

Synthesis method
Qhov ncaj qha hydration ntawm ethylene yog cov tshuaj tiv thaiv ncaj qha ntawm ethylene nrog dej nyob rau hauv lub xub ntiag ntawm tshav kub, siab thiab nyob rau hauv lub xub ntiag ntawm ib tug catalyst los tsim ethanol:
CH2═CH2 + H-OH → C2H5OH (Cov tshuaj tiv thaiv yog ua nyob rau hauv ob kauj ruam. Thawj kauj ruam yog tsim cov organic mercury compound nyob rau hauv ib tug dej-tetrahydrofuran tov nrog mercury ntsev xws li mercury acetate, thiab ces txo nws nrog sodium. borohydride.) - Ethylene tuaj yeem nqa tau los ntawm cov roj av tawg hauv cov khoom loj, nrog cov nqi qis thiab cov zis loj, uas tuaj yeem txuag tau. zaub mov ntau, yog li nws loj hlob sai heev.
Nws kuj tseem tuaj yeem hloov mus rau hauv syngas los ntawm kev lag luam thee tshuaj, ncaj qha los yog ua los ntawm kev lag luam hydrogenation ntawm acetic acid.
Thib peb, tus qauv zoo
Raws li cov neeg siv khoom xav tau, chav tsev tsim khoom ethanol tuaj yeem ncav cuag cov qauv tsim nyog (GB10343-2008 qib tshwj xeeb, qib siab dua, qib dav dav, GB18350-2013, GB678-2008) lossis lwm cov qauv thoob ntiaj teb.
Plaub, cov lus hais
Lub tuam txhab tuaj yeem ua tiav qhov project turnkey xws li cawv, tshuaj, tshuaj, DDGS.
Cov "Golden Character" hom distillation thiab cov khoom siv ntxiv muaj cov khoom lag luam hauv tsev ntau dua 40%. Nyob rau hauv 2010-2013, lub tuam txhab ranked thawj nyob rau hauv tib lub lag luam rau plaub lub xyoos sib law liag.
