A direct search method for determination of DAEM kinetic parameters from nonisothermal TGA data (note)
MetadataShow full item record
In this study, a simple direct search method to be used for the determination of distributed activation energy model (DAEM) kinetic parameters from the nonisothermal thermogravimetric analysis (TGA) data of coals has been introduced. Process steps of direct search method that depends on the grid technique have been given. The method has been applied to the nonisothermal TGA data of one Turkish coal and one imported coal, and DAEM kinetic parameters of these coal samples have been determined. Calculated model results from determined kinetic parameters have been compared with nonisothermal TGA data of the coals.
