Thermogravimetric studies of chitin and chitosan in air atmosphere were carried out at six rates of linear increase of the temperature. The kinetics and mechanism of the thermal decomposition reaction were evaluated from the TG data using recommended from ICTAC kinetics committee isoconversional calculation procedure of Kissinger-Akahira-Sunose, as well as 27 mechanism functions. The values of ...

Abstract Applying the isoconversional method to data obtained from thermogravimetric analysis (TGA) can provide vital kinetic information. In this work, thermal decomposition and oxidation of antidiabetic drug glimepiride is analyzed in presence N 2 O . The study was done with without metal oxide catalysts explore their potential application solid wastewater upgrading. conducted using analysis....

The parameters obtained from a kinetic analysis of thermoanalytical data often exhibit a conversion-dependent behavior. A novel incremental isoconversional method able to deal with this phenomenon is proposed. The kinetic model is directly fitted to the experimental data using nonlinear orthogonal least squares procedure. The data are processed without transformations, so their error distributi...

To better understand the thermochemical conversion for pyrolysis recycling of cable waste, kinetics typical filler was investigated in detail. Thermogravimetric experiments were conducted at different heating rates ranging from 5 °C/min−1 to 40 °C/min−1. Three degradation stages observed process pyrolysis. The influence air on superposition first two peaks also identified. activation energy cal...

In this study, thermogravimetric measurements of nylon-6/polyethylene double-layer pouch wastes were conducted in N2 under a constant heating-rate mode, and the multiple results analyzed terms degradation features specific temperatures. Experimental show that waste pyrolysis involves one reaction stage, all parameters appear to increase with heating rate. Kinetic analysis non-isothermal data wa...

The kinetics of mercury removal from solid wastes generated by chlor-alkali plants were studied. The reaction order and model-free method with an isoconversional approach were used to estimate the kinetic parameters and reaction mechanism that apply to the thermal decomposition of hazardous mercury wastes. As a first approach to the understanding of thermal decomposition for this type of system...
