Аннотация: The rheological properties of coke-pitch compositions are investigated after their mechanical activation (MA) treatment in the hydroblow-cavitation field for three compositions of a coke charge containing finely dispersed coke fractions. The rheological properties of these mixtures are compared with those not subjected to MA. It is established that, as a result of MA, plastic viscosity decreases. As the temperature increases, this quantity initially decreases and then becomes almost constant. The apparent activation energy of the viscous flow increases as the content of finely dispersed coke fraction increases and has the same order of magnitudes for compositions before and after MA.
