Abstract: | A new integral method of nonisothermal kinetic analysis has been developed with the dependence of the frequency factor on
the temperature (A = A
0
T
m
). The new integral method is obtained from the newly proposed approximation for the general temperature integral, which is
more accurate than the other existed approximations. For applications, nonisothermal thermoanalytical data obtained by theoretical
simulation have been processed. The results have shown that the newly proposed integral method is an ideal solution for the
evaluation of kinetic parameters from nonisothermal thermoanalytical data with the frequency factor dependent the temperature. |
