Antioxidant Activity of Asphaltene and Resinous Components in a Magnetic Field
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.
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.
