HIGH-TEMPERATURE COMPENSATION EFFECT OF DYNAMIC VISCOSITY IN MULTICOMPONENT HYDROCARBON MEDIA

Linear dependences connecting the preexponent to the activation energy of viscous fl ow in the Frenkel–Eyring equation have been obtained for multicomponent hydrocarbon media (high-boiling distillate fractions). For these media, the kinetic compensation effect has been established whose distinctive feature is its action in the temperature range including the temperature of thermal destruction (400–450^o C) of the indicated media. The obtained results have been confi rmed by statistical-processing data and make it possible to predict the dynamic viscosity of multicomponent hydrocarbon systems, such as tars and other high-boiling oil distillates.
