【摘要】 用吸附色谱分离法，根据减压渣油中的酸、碱性组分分布情况，将其分成烃、中性份、碱性份和酸性份，即氮化物的族组成分离．实验结果表明，用碱性氧化铝和酸改性的酸性氧化铝可以将不同渣油分离成四组分．其中，酸性化合物大部分浓集于酸性份中，碱性氮化物大部分浓集于碱性份中，部分非碱性氧化物浓集在中性份中．更多还原

【Abstract】 A adsorption-chromatography method is used to separate the vacuum residues into hydrocarbon. neutral fraction.basic fraction and acidic fraction. The results show that the vacuum residues are satisfactorily separated into four fractions with basic alumina containing 9% H₂O and perchloric acid/acetic acid modified by acidic alumina. Most of acidic compounds are included in acidic fraction, most of basic nitrogen compounds in basic fraction and part of non-basic nitrogen compounds in neutral fraction.更多还原
