Urea hauv Tsheb

UREA

urea hauv cov khoom vaj khoom tsev:

Urea, tseem hu ua carbamide, nrog rau cov tshuaj formula CH4N2O, yog cov organic compound uas muaj carbon, nitrogen, oxygen, thiab hydrogen. Nws yog dawb siv lead ua thiab yog ib yam khoom ntawm cov tsiaj protein metabolism.

Cov tsos mob: Cov xim tsis muaj xim lossis xim dawb zoo li lub ntsej muag lossis lub ntsej muag zoo li lub ntsej muag, cov khoom lag luam lossis cov khoom ua liaj ua teb yog xim dawb nrog cov khoom me ntsis reddish, tsw thiab saj tsis qab. Cov ntsiab lus nitrogen yog li 46.67%.

Solubility: soluble hauv dej, methanol, formaldehyde, ethanol, kua ammonia, thiab cawv, me ntsis soluble hauv ether, chloroform, thiab benzene. Tsis muaj zog alkaline.

urea hauv tsheb Lub Hom Phiaj:

Kev xaiv txo cov neeg ua haujlwm rau combustion pa roj denitrification, nrog rau tsheb urea, muaj 32.5% high-purity urea thiab 67.5% deionized dej.

Selective catalytic reduction (SCR) tso pa tawm tom qab kev kho mob yog ib qho cuab yeej siv ammonia uas tsim los ntawm cov tshuaj pyrolysis ntawm urea hauv combustion exhaust los xaiv catalyze qhov txo cov tshuaj tiv thaiv nrog nitrogen oxides (NOx) hauv tsheb tso. Nws yog ib qho tseem ceeb thiab cov thev naus laus zis thev naus laus zis los txo cov khoom tsis zoo NOx hauv combustion pa gases xws li boilers thiab diesel xyaw. Lub SCR system yog ib qho tseem ceeb uas ua tau raws li cov cai nruj me ntsis ntawm cov tsheb niaj hnub, xws li Euro IV / Euro V / Euro VI (Lub Tebchaws IV / Lub Tebchaws V / Lub Tebchaws VI). Automotive urea hu ua AdBlue hauv Tebchaws Europe thiab DEF hauv Tebchaws Meskas.
