Abstract
The effect of mechanochemical treatment on the emulsification of high-viscosity petroleum products is reported. Thermally stable water-in-oil emulsions, whose viscosity is five times lower than the viscosity of the original petroleum product, are prepared for the first time by mechanochemical treatment in the presence of a surfactant. The critical fluxing temperature, thermal properties, and viscosity of asphalt emulsions prepared by mechanochemical treatment is identical to those of residual oil. A mechanism is suggested to explain the formation of inverted aqueous emulsions of petroleum products rich in tars and asphaltenes.
