This article is devoted to development of theoretical basis for the non-reagent dementalization of high-viscosity oils in the process of demineralization and dehydration of oil in fields for the extraction of non-ferrous metals, as well as to exclude the negative influence of metals on the depth of oil refining, the durability of catalysts, the efficiency of refining processes and the quality of oil products. The results of analysis of the current-voltage characteristic proved that all values of the electrical characteristics of the above process are interrelated. Also, a determination was made of the optimal operating conditions of the device for obtaining productive solutions. During the research it was found out that the kinetics of the oxidative decomposition of vanadocene dichloride is accelerated by a specific acidic electrophilic catalysis in which there is a rapid emerging of all protolytic equilibrium in the solution and the subsequent slow transformation of the protonated reagent in the reaction products

In this article presents an extensive experimental results of the research of a vanadocene dichloride oxidative breakdown mechanism observable during the vanadium extraction from heavy oil. Particularly, an influence of sulfuric and nitric acid consumption on the process of demetallization of Karazhanbas oilfield heavy oil and kinetics of this reaction were considered. It was defined that the reaction will be carried out more effective in the case of substitution of sulfuric acid as an electrophilic catalyst for immobilized Lewis acids or mineral carrierimpregnated by hydrogen acids. Immobilized catalyst use allows to exclude involvement of nitric acid as an oxidizing agentin the process of vanadocene dichloride oxidative breakdown. Also the influence of ultrasonic influencepower during the oil emulsification and electroactivated aqueous solution to the kinetics demetallization were defined. New technological scheme were proposed, which provides "oil -electroactivated aqueous solution" emulsion preparation directly in oil-bearing strata. This engineering solution is able to reduce the number of process technological stages and to improve engineering-and-economical performance of demetallization.
