The kinetics of release of volatile substances when coke-pitch composition was heated under isothermal conditions

The kinetics of release of volatile substances when coke-pitch composition was heated under isothermal conditions had been examined. Studies were conducted on the composition with different content of pitch and coke charge of different granulometric composition.Gas content was identified using the volumetric method. The measurements were performed for samples of coke, pitch and coke-pitch composition. The results were presented in the form of kinetic dependencies. Found that with increasing degree of dispersion of coke charge the limit loses of low-boiling components of the pitch increase. With increasing temperature, the limit loses of pitch increase. The evaporation of volatile components occurs in the diffusive regime.
