چکیده انگلیسی
Influence of crystal form and morphological characteristics of CaCO3 samples with different structural (calcite, aragonite, low-crystalline and amorphous) and morphological (medium particle dimensions and shapes) characteristics on the kinetic of time-limited desulfurization process of coal combustion gases between 1030 and 1150 K was determined. Kinetic parameters (activation energies and pre-exponential factors of sulfurization reaction) were established. Correlations of the above-mentioned kinetic parameters of the reaction with size of particles (within the same crystal phase), morphology of particles or particle structure were explained by the difference in distribution of energy of active centers within border phase of interaction.
