METHOD FOR OBTAINING NANOSCALE CATALYST BASED ON MIXED IRON OXIDE FOR INTENSIFICATION OF HEAVY RAW HYDROCARBON MATERIAL AND CATALYST OBTAINED BY THIS METHOD Russian patent published in 2018 - IPC B01J23/745 B01J37/04 B01J37/30 B01J37/34 C01G49/08 

FIELD: technological processes.

SUBSTANCE: method for preparation of nanoscale catalyst based on mixed iron oxide Fe₃O₄ to intensify extraction of heavy raw hydrocarbon deposits that are conducted at room temperature and atmospheric pressure by mixing two pre-prepared aqueous solutions. First aqueous solution consists of mixture of Fe²⁺ and Fe³⁺, the second aqueous solution consists of nonsolvent – ammonium hydroxide, hydroxides of alkaline-earth metals, and stabilizing agents-surfactants. Mixing process is carried out with continuous cavitation action of ultrasonic disperser for thirty minutes to obtain mixed iron oxide sol of Fe₃O₄, are treated with ion exchange resins without turning off cavitation effect on mass until pH value of mass reaches a neutral value to obtain desired product. Particle size of catalyst is in the range of 50 to 165 nm with volume concentration of at least 90 % of volume of obtained desired product. Also the invention relates to a catalyst obtained by the method described above.

EFFECT: expansion of list of catalysts with optimum particle size for intensification of extraction of heavy carbon raw materials in conditions of layer of high-viscosity oils and natural bitumen.
