FIELD: preparation of emulsions. SUBSTANCE: multiphase emulsion includes aqueous continuous phase, phase of petroleum product blobs dispersed in continuous aqueous phase, phase of inner aqueous droplets dispersed in phase of petroleum product blobs and water-insoluble compound suspended in phase of inner aqueous droplets. Method of preparation of emulsion is also described. EFFECT: enhanced stability of multiphase emulsion; minimum amount of surface-active agent; availability of additives resistant to corrosion of metals in oil phase; ease of transportation and combustion of target fuel product. 26 cl, 2 dwg, 6 tbl, 3 ex
