抚顺页岩油柴油馏分含氧、氮化合物类型研究

STUDY ON OXYGEN-CONTAINING AND NITROGEN-CONTAINING COMPOUNDS OF DIESEL DISTILLATE FROM FUSHUN SHALE OIL

对抚顺页岩油柴油馏分经酸碱抽提得到的酸性组分、碱性组分及柱分离中性组分得到的极性组分进行GC-MS表征,结果表明:抚顺页岩油柴油馏分中鉴定出71种含氧化合物和77种含氮化合物。酸性组分中的含氧化合物以酚类化合物为主,其相对质量分数为52.7%;中性组分中的含氧化合物以脂肪酮和芳香酯为主。碱性组分中的氮化物主要是六元环杂氮化合物,以喹啉类化合物为主,其相对质量分数为44.1%;中性组分-3的含氮化合物主要是脂肪腈类。

Acid fraction, base fraction,and different polar fraction of diesel distillate from Fushun shale oil were characterized by GC-MS. The result showed that 71 oxygen-containing compounds and 77 nitrogen containing compounds were identified in diesel distillate from Fushun shale oil . The oxygen- containing compounds in the acid fraction were mainly phenols,the content of them was 52.7%. The oxygen-containing compounds in neutral fraction were esters and ketones . The base fraction mainly included hexa-heterocycle nitrogen containing compounds, such as quinolines, the content of quinolines were 44.1%. The nitrogen-containing compounds in neutral fraction-3 were mainly aliphatic nitriles.
