Abstract

New equations have been proposed for the evaluation of the kinetic parameters from non-isothermal thermogravimetry. The Arrhenius temperature integral. In p(x), values were computed from the recently proposed series and approximations. The validity of the new equations has been confirmed by the analysis of theoretical and experimental thermogravimetric curves. The kinetic parameters computed using the proposed equations show better agreement for theoretical TG curves than the well-known methods.
