In this article, experimental research results of super-viscous oil conversion in supercritical water are shown. Reaction mixtures consisting of super-viscous oil, carbon substances and complex catalytic additive were influenced by the conversion. A catalytic additive is a mixture of dispersed nickel and copper salts of carbonic acid, aluminum oxide and coal. A content increase of paraffinonaphthenic hydrocarbon up to 76.2 wt % against 40.8 wt % of an initial oil is a main characteristic of supercritical conversion products. Light hydrocarbons formation is implemented by aromatic, resinous and asphaltene components destruction. Based on experimental methods of super-viscous oil conversion in a supercritical water, a principal technological conversion scheme is proposed.
