Abstract
A comparative analysis of products of hydrothermal transformation of super-viscous oil above the critical point of water at elevated temperatures of 375-385°C and pressures of 22-23 MPa in the presence of coal and oxides of iron, aluminum, copper and nickel was carried out. The regularities of changes in the structural-group and component composition, as well as the physicochemical properties of aquathermolysis products of super-viscous oil of B2 type of Ashalchinskoye field, were established. It was shown that destruction of high molecular weight components of super-viscous oil under conditions of its watermolysis in the presence of manganese and iron oxides lead to the formation of low-boiling hydrocarbon fractions. The predominant course of the destruction of resinous components, aliphatic substituents of asphaltenes and branched aliphatic structures with the redistribution of alkanes of normal structure towards their low molecular weight homologs has been established.
