WebFlynn-Wall-Ozawa (FWO) method The FWO method [16, 17] is based on the following equation: (2) It is used to determine the apparent activation energy for given values of conversion. The activation energy for different conversion values can be calculated from a plot of lnβ versus 1000/T whose intercept is ln AE a /R. Friedman method WebTherefore, Ozawa–Flynn–Wall equation (Eq. (1)) was applied to describe the overall degradation reac-tion and the activation energy was calculated as a func-tion of the degree of reaction. log
