摘要
研究满足国Ⅲ排放标准的汽油轿车燃烧工业甲醇后的常规和非常规污染物排放特性.采用热脱附-气相色谱/质谱联用技术和高效液相色谱法对汽油和工业甲醇燃料的非常规污染物排放进行定量及定性研究.研究结果表明:甲醇轿车的常规污染物CO,THC(总碳氢化合物)和NOx排放低于汽油轿车;非常规排放污染物中,甲醇汽车的醛酮尾气排放高于汽油轿车,其甲醛的排放量约是汽油车的6倍,而其挥发性有机物(VOCs)排放的总量只有汽油车的1/2左右.
Regulated and unregulated emission of a gasoline vehicle that meets national standard No. Ⅲ and fuelled with methanol were investigated. Thermal desorption-gas chromatography/ mass spectrometer (TD-GC/MS) was used for aromatic compounds emission and high pressure liquid chromatography (HPLC) was used for aldehyde and alkone emission. Test results showed that THC, CO and NO~ emission from the methanol vehicle were less than the case using gasoline, but the aldehyde and alkone emission appeared higher than the gasoline vehicle, especially its formaldehyde emission is six times than the gasoline vehicle, but the volatile organic compounds(VOCs) emission amounted to only half that of the gasoline emission.
