摘要

In order to investigate the influence of temperature on behavior of calcium carbonate decomposition

especially on kinetic parameters of the decomposition reaction

the analytically pure calcium carbonate was calcined on a self-built large dose thermogravimetric analyzer.The results indicated that

with an increase in the reaction temperature

the reactivity index of calcium carbonate decomposition increased at stage state while the kinetic parameters decreased at stage state.Moreover

both the reaction indices and the kinetic parameters can be divided into three stages and the temperature turning points in different stages were the same.The phase boundary reaction(cylindrical symmetry) theory was more suitable for calcium carbonate calcination under N 2 atmosphere.The change trend of the logarithm of reaction activation with temperature was similar as that of the pre-exponential factor.There existed good liner relationship and kinetic compensation effect between them.The isokinetic temperature of the CaCO 3 calcination was 842℃ and the reaction rate constant was 0.104 9min-1 derived by the compensation coefficients.
