COMPOSITION OF REAGENTS FOR CHEMICAL CONVERSION OF HEAVY OIL WHEN PUMPING STEAM Russian patent published in 2020 - IPC B01J23/00 B01J23/74 B01D11/04 B82Y40/00 

FIELD: chemistry.

SUBSTANCE: disclosed is a composition of reagents for chemical conversion of heavy oil in steam pumping and intensification of oil recovery, which includes a nano-sized catalyst based on a mixed oxide of transition metals, where metals are selected from the group: Cr, Mn, Fe, Co, Ni, Cu, Zn, Mo, hydrogen-donor nefras solvent C4-155/205, and an alcohol-alkaline composition which is a sodium hydroxide solution in ethyl alcohol with concentration of 0.1 to 20 wt. %, where the reagent composition is contained in the following ratio: nano-sized catalyst based on mixed oxide of transition metals: nefras C4 - 155/205: alcohol-alkaline composition = 1–30 wt. %: 98–50 wt. %: 1–20 wt. %.

EFFECT: technical result is higher efficiency of refinement and conversion of heavy oil due to combined use of nanosized catalyst, hydrogen-donor solvent and alcohol-alkali composition in steam-thermal action.
