| 摘 要： | 采用碱性氧化铝和高氯酸／冰乙酸改性的酸性氧化铝两步法将减压渣油分成烃、中性分、碱性分和酸性分。用非水电位滴定法，元素分析法及红外光谱法对渣油及其组成中的氮化物进行分析鉴定。结果表明，四种渣油的中性份、碱性份和酸性份中，均以非碱性氮含量最高，弱碱性氮含量最少。

| Abstract: | Vacuum residues are separated into hydrocarbon, neutral, basic and acidic fractions with adsorption chromatography. The four fractions are determined and characterized by non-aqueous potentiometric titraction, microcoulometric and infrared spectroscopy. The result shows that the content of non-basic nitrogen of neutral, basic and acidic fractions is high.and the weak basic nitrogen is less. |
