The analysis of the bitumen deposits Ashalchinskoye cracking products (content of fractions boiling up to 360 °C - 32.5 % wt., respectively) has been conducted. It shows the impact of nanosized powders of molybdenum and copper oxide on the cracking process. It has been found that the presence of nanosized molybdenum powder leads to the formation of large amounts of gas and oil degradation due to the resins compared with nanosized copper oxide powder.
