Abstract

The antioxidant activity of resin–asphaltene components isolated from two crude oils of different compositions was analyzed before and after exposure to a magnetic field using the voltammetric method of oxygen electroreduction. The antioxidant activity of the test asphaltenes and weakly polar and polar resins increased or decreased with increasing sample concentration in a supporting electrolyte solution. Petroleum antioxidants are part of a complex colloidal structural system, and they are associated with it by associative interactions that arise as a result of changes in the size and activity of associates in the petroleum system as a whole.

沥青和树脂成分在磁场中的抗氧化活性

摘要利用氧电还原伏安法分析了从两种不同成分的原油中分离出来的树脂-沥青质成分在暴露于磁场前后的抗氧化活性。测试沥青质、弱极性树脂和极性树脂的抗氧化活性随着支持电解质溶液中样品浓度的增加而增加或减少。石油抗氧化剂是复杂胶体结构系统的一部分，它们与该系统的关联作用是由于整个石油系统中关联物的大小和活性发生变化而产生的。

期刊介绍： The journal publishes theoretical and applied articles on the chemistry and physics of solid fuels and carbonaceous materials. It addresses the composition, structure, and properties of solid fuels. The aim of the published articles is to demonstrate how novel discoveries, developments, and theories may be used in improved analysis and design of new types of fuels, chemicals, and by-products. The journal is particularly concerned with technological aspects of various chemical conversion processes and includes papers related to geochemistry, petrology and systematization of fossil fuels, their beneficiation and preparation for processing, the processes themselves, and the ultimate recovery of the liquid or gaseous end products.
