Tab sis benzene yog cov tshuaj tsw qab uas muaj cov ntsiab lus carbon ntau dua (carbon rau hydrogen piv). Yog li nws tsis tau oxidized kiag li thaum combustion thiab muab tawm sooty nplaim taws.
Yuav ua li cas ua kom nplaim taws soo?
Cov pa roj carbon tsis zoo tsis hlawv tag nrho thiab muab cov nplaim hluav taws uas tsis muaj hluav taws kub los yog ib nrab hlawv cov pa roj carbon monoxide. Xws li cov nplaim taws muaj xim daj thiab ua paug. Nws hu ua nplaim taws.
Yuav ua li cas cov nram qab no muab cov nplaim daj rau combustion?
Unsaturated hydrocarbons zoo li ethine tsim cov nplaim daj thaum hlawv hauv cov pa vim tsis tiav combustion hauv huab cua.
Vim li cas combustion qee zaum ua kom muaj hluav taws kub?
Soot cov ntaub ntawv los ntawm kev ua kom tsis tiav. Txhawm rau ua kom tsis tiav combustion es tsis txhob ua kom tiav combustion, cov roj yuav tsum hlawv ntawm qhov kub thiab txias nrog me ntsis txo cov pa oxygen. Thaum cov roj kub hnyiab, nws tawg mus rau hauv cov khoom me me uas suav nrog soot, uas tawm mus ua cov hmoov av tsaus nti.
tshuaj lom neeg lub npe yog dab tsi?
Soot (qee zaum hu ua carbon dub) yog tsim thaum hydrocarbon fuels raug hlawv. Peb lub tswv yim yog tias polynuclear aromatic hydrocarbon (PAH) molecules yog cov tseem ceeb ntawm cov hmoov tshauv, nrog rau cov PAH molecules ib tus neeg tsim cov pawg pawg uas agglomerate rau hauv cov ntsiab lus.(PP).
