FIELD: mining; petrochemistry.

SUBSTANCE: invention relates to the field of mining and petrochemistry, in more detail – to the oil industry, and can be used in the development of deposits of hard-to-recover hydrocarbon reserves. Described is a method of producing an amphiphilic catalyst precursor for intensifying the process of aquathermolysis of high-viscosity oil, which consists in taking a ready-made or producing a freshly prepared hydroxide of a transition metal from the series: Fe, Ni, Co, Cu, Mo, Mn, Al, Zn, Cr, for this purpose, an aqueous solution of an inorganic salt of the corresponding transition metal from the series: sulphate, chloride, nitrate are mixed with an aqueous solution of an alkaline agent from the series: sodium hydroxide, potassium hydroxide, ammonium hydroxide in molar ratio from 1:2 to 1:3 depending on the valence of the transition metal at room temperature for 0.5-2 hours; obtained metal hydroxide precipitate is washed first with distilled water to pH=7 and then with acetone and dried in a drying cabinet at temperature of 60 °C for 2 hours; Then the obtained transition metal hydroxide precipitate is mixed with alkylbenzene sulphonic acid in molar ratio of 1:2 to 1:3 depending on transition metal valence; then adding an azeotropic agent toluene or xylene in amount of 150 ml with continuous stirring for 1 to 20 minutes and heating to temperature of 80 °C to 95 °C with installation of a reverse cooler for 1-3 hours, wherein the formed as a result of the reaction water is removed by azeotropic distillation at 95 °C; then for complete removal of toluene or xylene residue after azeotropic distillation from synthesis product vacuum evaporation is used at temperature of 40 °C and vacuum of 77 mbar to constant weight of the synthesis product. Composition of the amphiphilic catalyst precursor for intensifying the process of aquathermolysis of high-viscosity oil, obtained by method 1, contains the following, wt. %: ligand-forming component alkylbenzene sulphonic acid 85-95; transition metal from the series: Fe, Ni, Co, Cu, Mo, Mn, Al, Zn, Cr 5-15.

EFFECT: intensification of upgrading and high degree of conversion of high-viscosity oil.
