Model-Fitting Approach to Kinetic Analysis of Non-Isothermal Oxidation of Molybdenite

model-fitting approach to kinetic analysis of non-isothermal oxidation of molybdenite

the kinetics of molybdenite oxidation was studied by non-isothermal tga-dta with heating rate 5 ºc.min-1.the model-fitting kinetic approach applied to tga data .the coats-redfern method used for model fitting. the popular model-fitting gives excellent fit for non-isothermal data in chemically controlled regime. the apparent activation energy was determined to be about 34.2 kcalmol-1 with pre-ex...
