Kinetic analysis of thermogravimetric data

Kinetic Parameters from Thermogravimetric Data

The "differential" method of Achar, Brindley and Sharp (ABS) and the "integral" one of Coats and Redfern (CR) are applied to the dehydration of BaBr2-H20 and HCOOLiH20 and to the thermal decomposition of Pb(SCN)2, and the kinetic parameters so obtained are compared with those deduced isothermally. The results of the ABS method, at the lowest heating rate (q = 1.2 K min— '), agree well with the ...

Thermogravimetric analysis of waxes.

Differential thermal analysis and calorimetric analysis of commercial and dental waxes have been reported in the dental literature."2 Thermogravimetric analysis is described in most textbooks on thermal analysis3-5 and is essentially a method of measuring the weight of a sample as a function of temperature or as a function of time at a fixed temperature. The purpose of this study was to examine...

Thermogravimetric and kinetic analysis of the decomposition of Solid Recovered Fuel from municipal solid waste

Thermogravimetric study and kinetic analysis of fungal pretreated corn stover using the distributed activation energy model.

Non-isothermal thermogravimetry/derivative thermogravimetry (TG/DTG) measurements are used to determine pyrolytic characteristics and kinetics of lignocellulose. TG/DTG experiments at different heating rates with corn stover pretreated with monocultures of Irpex lacteus CD2 and Auricularia polytricha AP and their cocultures were conducted. Heating rates had little effect on the pyrolysis proces...

Thermal Decomposition of Natural Fibers: Global Kinetic Modeling with Nonisothermal Thermogravimetric Analysis

The modeling of thermal decomposition process of ten natural fibers commonly used in polymer composite industry was performed by assuming a global model occurring within the entire degradation range with consideration of fiber as one pseudocomponent. Málek method with activation energy values previously obtained was applied to the modeling process. Careful calculation and evaluation indicated t...
