Presently intensification of heavy oil production, particularly by applying various catalytic systems, is very attractive and relevant task for many researchers. Catalysts intensify a destruction process of high molecular compounds such as resins and asphaltenes. Thus, providing irreversible viscosity reduction of nonconventional crude oils. In this regard, investigation of ultra-dispersed catalysts based on transition metals is of current interest. The small particle sizes of catalysts yield a strong activity dur...
