CALCULATION OF ACTIVATION-ENERGY AND PREEXPONENTIAL FACTORS FROM RISING TEMPERATURE DATA AND THE GENERATION OF TG AND DTG CURVES FROM A-VALUES AND E-VALUES

After reviewing present methods of evaluating E, the activation energy, and A, the pre-exponential constant, and pointing out some of the inherent weaknesses of the method, a technique is outlined whereby a DTG and/or TG curve may be produced for direct comparison with experimental curves by assuming values for A and E and using finite difference techniques to produce such a curve.
