Model-Fitting Approach to Kinetic Analysis of Non-Isothermal Oxidation of Molybdenite
نویسندگان
چکیده مقاله:
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-exponential factor about 108 sec-1 for extent of reaction less than 0.5.
