桦甸页岩油柴油馏分中含氮、氧化合物结构组成分析

AN ANALYSIS OF THE COMPOSITIONS OF NITROGEN AND OXYGEN COMPOUNDS IN DIESEL DISTILLATE FROM HUADIAN SHALE OIL

利用酸碱萃取及柱色谱分离的方法对桦甸页岩油柴油馏分中的氮化物及氧化物进行分离富集,并利用GC-MS对其组成结构进行分析。结果表明,桦甸页岩油柴油馏分中的氮化物及氧化物种类较多,结构较复杂。其中,含氮化合物是以含1个氮原子、环数为1～3个的杂环化合物为主,包括吡啶类、苯胺类、喹啉类、吖啶类等,还有一部分直链腈类化合物。含氧化合物以酚类等酸性氧化物为主,如苯酚类、萘酚类等,还有一些茚醇类和芴醇类、脂肪酮类以及少量芳醚类化合物。

The nitrogen and oxygen compounds in diesel distillate from Huadian shale oil were separated and concentrated by acid-base extraction and column chromatogram separation. The compositions of these nitrogen and oxygen compounds were analyzed by GC-MS. Results indicated that the nitrogen compounds in said diesel distillate were mainly composed of 1-3 ring compounds, such as pyridine,quinoline,indole,carbazole and their alkylated derivatives,as well as aliphatic nitriles. The majority of oxygen compounds found in the distillate were acidic oxides, for example, phenol, naphthol and their alkylated derivatives.
