Thermogravimetric analysis of pulps part II: Kinetics for dynamic thermogravimetric analysis

Wood Science and Technology, 1976
This paper surveys the different kinetic schemes that have been employed with dynamic thermogravimetric analysis and discusses their advantages and shortcomings with particular reference to cellulose. It is concluded that the differential method of Friedman [1965] and the integral method of Flynn and Wall [1966] are the best approaches for kinetic ...

Thermogravimetric Analysis of Lubricants

SAE Technical Paper Series, 1983
<div class="htmlview paragraph">A novel thermogravimetric analysis test method has been developed for the evaluation of lubricants. It involves superimposing the thermogravimetric trace of the sample in argon over the trace produced in oxygen atmosphere.

Thermogravimetric analysis of cellulose

Journal of Polymer Science Part A-1: Polymer Chemistry, 1968
AbstractAn application of TGA technique to elucidate the chain reaction mechanism of cellulose pyrolysis is discussed. The mathematical expressions for isothermal kinetics are modified for use with temperature‐programmed kinetics. It is shown that in temperature‐programmed kinetics, the initial reaction should theoretically be a pseudo zero‐order type,

Thermogravimetric Analysis of Composite Restorative Resins

Journal of Dental Research, 1972
Thermogravimetric analyses of six commercial brands of composite restorative resins were performed at temperatures from 25 to 700 C in air with a heating rate of 9.5 Cl minute. The reported ashed weight was assumed to be the filler weight. The thermogravimetric technique as applied to these composite resins was effective in deriving basic information ...

Thermogravimetric analysis and fast pyrolysis of Milkweed

Bioresource Technology, 2014
Pyrolysis of Milkweed was carried out in a thermogravimetric analyzer and a bubbling fluidized bed reactor. Total liquid yield of Milkweed pyrolysis was between 40.74% and 44.19 wt% between 425 °C and 550 °C. The gas yield increased from 27.90 wt% to 33.33 wt% with increasing reaction temperature. The higher heating values (HHV) of the Milkweed bio-oil

Thermogravimetric Analysis and Devolatilization Kinetics of Wood

Industrial & Engineering Chemistry Research, 2002
Thermogravimetric curves have been measured at a heating rate of 5 K/min for several hardwoods (beech, alder, birch, and oak) and softwoods (Douglas fir, two pine species, redwood, and spruce), whose chemical composition varies within the usual standards.

Thermogravimetric analysis of biowastes during combustion

Waste Management, 2010
The combustion of sewage sludge (SS), animal manure (AM) and the organic fraction of municipal solid waste (OFMSW) was assessed and compared with that of a semianthracite coal (SC) and of a PET waste by thermogravimetric (TG) analysis. Differences were found in the TG curves obtained for the combustion of these materials accordingly to their respective
