Simultaneous thermogravimetry–calorimetry study on the combustion of coal samples: Effect of heating rate

open access: green, 2011
Combustion characteristics of two different coal samples were investigated using power compensating type differential scanning calorimeter (DSC) and thermogravimetry (TG-DTG) at different heating rates (5, 10 and 15 degrees C/min).

Non-Isothermal Thermogravimetry of Selected Tropical Woods and Their Degradation under Fire Using Cone Calorimetry

open access: yesPolymers, 2021
For selected tropical woods (Cumaru, Garapa, Ipe, Kempas, Merbau), a relationship was established between non-isothermal thermogravimetry runs and the wood weight loss under flame during cone calorimetry flammability testing.

Is Thermogravimetry an efficient alternative to gas chromatography in degree of biodiesel conversion?

open access: yesJournal of Thermal Analysis and Calorimetry, 2018
This work aims to determine if thermogravimetry could be used to determine the degree of conversion of soybean oil to biodiesel without knowing the amount of ester in the sample, comparing the results with the values obtained by the standard method, gas ...

Characterization of lignocellulose biomass and model compounds by thermogravimetry

open access: yesEnergy Sources, Part A: Recovery, Utilization and Environmental Effects, 2017
In this research, combustion characteristics of lignocellulose biomass (hazelnut shell) and three main components (cellulose, hemicellulose, and lignin) were investigated using thermogravimetry (TGA-DTG) technique at different heating rates. The ignition,

General treatment of the thermogravimetry of polymers

open access: bronzeJournal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1966
Theoretical equations are developed for typical decompositions of polymers including those in which the volatilization does not follow a simple "reaction order" and those made up of a composite of several reactions of differing energies of activation. The effects of order, activation energy, heating rate and temperature dependence upon the calculated ...

Thermogravimetry of Selected Bentonites

open access: yesEnergy Sources, 2002
In this research the application of thermal analysis techniques (TG-DTA) to the characterization of bentonite samples is presented. The thermal behavior of 4 bentonite samples was investigated using simultaneous thermogravimetry (TG/DTG) and differential thermal analysis (DTA) techniques. It was observed that all bentonite samples exhibit 2 weight loss
