| Popis: | An experimental investigation was conducted to analyze the absorption characteristics of deposited diesel soot by differential thermal analysis, thermal gravimetric analysis, and solid phase micro-extraction gas chromatography analysis. The results showed that dry diesel soot contained 2–3%w (percent by weight) of water and a maximum of 5%w hydrocarbons. Water wetted soot contained up to 40%w water, while diesel wetted soot contained up to 60%w hydrocarbons. The hydrocarbons extracted from the soot were primarily hydrocarbons higher than C12H26 with little evidence of lighter hydrocarbons. |
