将大庆、孤岛和单家寺减压渣油用含水4.0％的碱性氧化铝吸附色谱和磷酸改性的硅胶吸附色谱分离为烃组分、中性份、碱性份和酸性份。用非水电位滴定法和元素分析法测出了减渣及其各个组分的酸值、强碱氮含量、弱碱氮含量和非碱氮含量。分析了减渣的酸性化合物、碱性氯化物和非碱性氮化物在各个组分中的分布情况。减渣的酸性化合物几乎都分布于酸性份中,而碱性氯化物60％一70％的分布于碱性份中。用红外光谱法定性分析了各组分中的主要类型的氮化物。
Residues in Daqing, Gudao and Shanji Temple were separated into hydrocarbon fraction, neutral fraction, alkaline fraction and acidic fraction by basic alumina adsorption chromatography with water containing 4.0% and phosphoric acid modified silica gel adsorption chromatography. The acid value, strong base nitrogen content, weak base nitrogen content and non-base nitrogen content of slag-reducing and its components were measured by non-aqueous potentiometric titration and elemental analysis. The distribution of acidic compounds, basic chlorides and non-basic nitrides in the slag was analyzed. Almost all of the slag-reducing acidic compounds are distributed in the acidic portion, while 60% to 70% of the basic chloride is distributed in the basic portion. The main types of nitrides in each component were qualitatively analyzed by infrared spectroscopy.
