Extracting mathematically exact kinetic parameters from experimental data on combustion and pyrolysis of solid fuels

AbstractThe present paper has examined the most common mathematical methods for obtaining both the activation energy and the pre-exponential factor from 'raw' experimental data on combustion and pyrolysis of solid fuels. Four commonly used integral methods and a very popular differential method have been scrutinised. The integral method based on the Senum and Yang approximation which utilises a non-linear regression has provided both kinetic parameters within 0˙5% error from the exact values. The method is exact, simple and therefore powerful.
