Abstract
Specific features of the distribution of vanadium and nickel during fractionation of heavy oil resins were examined using the example of heavy sulfurous oils from the Permian and Carboniferous deposits of the Volga-Urals oil and gas basin (Russian Federation). Fractionation of the resins was performed by silica gel column chromatography, followed by extraction with dimethylformamide (DMF). It was found that, during fractionation by adsorption chromatographic separation and extraction, vanadium and nickel compounds in the resins were predominantly distributed into the components with reduced content of carbonyl and carboxy groups, as well as of aliphatic structures.

吸附色谱分离萃取重质原油树脂连续分馏过程中钒和镍的分布
摘要
以来自伏尔加-乌拉尔油气盆地(俄罗斯联邦)二叠纪和石炭纪沉积物的重质含硫油为例,研究了重油树脂分馏过程中钒和镍的分布特征。树脂的分级通过硅胶柱色谱法进行,然后用二甲基甲酰胺(DMF)萃取。结果表明,在吸附色谱分离和萃取分馏过程中,树脂中的钒和镍化合物主要分布在羰基和羧基含量降低的组分以及脂肪族结构中。
