Abstract: Nitrogen compound distribution in catalytically cracked diesel fuel and its hydrogenated oil can be studied by gas chromatography/microcoulombmetry. It has been found that the basic nitrogen compounds in the oil are largely Anilines and quinolines, and the nonbasic nitrogen compounds indoles and carbaroles. The content of non-basic nitrogen compound, is 3-5 times more than that of basic nitrogen-compound and the percentage of distribution of nitrogen-compounds in the four types of catalytically cracked diesel fuel are about the same. The conditions of hydrogenation being suitable, nearly all the quinolines in basic nitrogen-compounds could be removed, and indoles in non-basic nitrogen greatly reduced. Non-basic nitrogen is directly syringed without extraction, It avoids the error caused by extraction.

摘要： 本文用气相色谱/微库仑法首次对催化柴油及其加氢精制生成油的碱性氮化物和中性氮化物的类型与分布进行了较完整的研究。发现催化柴油中碱性氮化物主要是苯胺类和喹啉类,中性氮化物主要是吲哚类和咔唑类。中性氮化物约为碱性氮化物的3～5倍。四种催化柴油中各氮化物类型占总氮的相对百分数基本上在同一水平。加氢精制条件选择适当,碱性氮中喹啉类能全部脱除,中性氮中吲哚类可显著减少。文中中性氮不经抽提浓缩,直接注样,避免了中性氮抽提浓缩所引起的显著误差。
