Kinetic modelling of coking coal fluidity development

“…For Model B, the rate constant was very much alike in specific ranges of temperature. The results are in line with those presented by Gerjarusak [30] considering limited range of coal used and simplified assumption of theirs model.…”

“…The data were validated against measured coal viscosity. The authors did not find a relationship between coal rank and kinetic parameters [30].…”

“…The most advanced work is [30], in which the multiple independent parallel reaction model was used to describe the isothermal kinetics of plasticity formation due to the metaplast generation and depletion. Using a nonlinear leastsquares regression routine, the activation energy and its variance for each chemical reaction step were fitted to the experimental data.…”
