DTG peak maximum simply refers to point/temperature where the weight loss rate is maximum (in case of non-isothermal runs) or in other word; inflection point of chemical or physical event. Of course, rate DOES change with respect to the composition. Therefore, conversion values would be different at the DTG peak points of different samples.

Ali Durmus Thank you very much for the answer.

Heating rate is another parameter which affects both the peak temperature and the conversion. So be careful about your conclusions.

Ersan Kalafatoglu - Will there be an effect even if the heating rate is the same for all conditions?

Peak temperatures will not change.

You can obtain kinetic data using the shifts of the peaks at different heating rates (better with the DSC runs instead of TGA).

Ersan Kalafatoglu -Thank you very much

I agree with Ali Durmus
