“…This result suggested that thermal degradation occurred in two main reaction zones for the untreated sample. Similar curves of the thermal degradation of lignocellulosic fibers have been reported earlier (Mansaray and Ghaly 1999;Alvarez and Vazquez 2004;Ndazi et al 2007b). The first reaction range at around 352 °C in the untreated sample resulted in the final degradation of hemicelluloses (Alvarez and Vazquez 2004), conversion of volatile products (Mansaray and Ghaly 1999), and splitting of aliphatic chains of lignin and C-C bonds of the aromatic ring (Le Van 1989).…”

The first reaction range was not observed in the treated samples due to significant decomposition of hemicellulose, lignin, wax substances, and natural oils already during the alkali treatment (Meszaros et al 2007;Ndazi et al 2007b).…”

This study evaluates the effect of 1% to 5% NaOH treatments of cotton stalk particles on the chemical composition and physical and mechanical properties of particleboards produced with this material. Gas chromatography and Fourier transform infrared (FTIR) spectroscopy indicated that the extractive, hemicellulose, and lignin content of the particles decreased during the alkali treatments, whereas the cellulose content increased. Thermogravimetric analysis (TGA) indicated that the untreated particles exhibited higher thermal stability than the particles treated with NaOH. The decrease in thermal stability of alkali-treated particles seems to be due to degradation of chemical components. Alkali treatments raised water absorption (WA) and thickness swelling (TS) of the produced particleboards. Except for 1% NaOH, the treatments reduced the modulus of elasticity (MOE), modulus of rupture (MOR), and internal bond (IB) strength in relation to the board made with untreated particles. The 1% NaOH treatment of cotton stalks was more effective and beneficial, leading to particleboards with satisfying MOE, MOR, and IB values that met the requirements for general-purpose particleboards used in dry conditions, as indicated by the TS-EN 312 (2012) standard.

In this work, thermogravimetric analysis is carried out on four different biomass samples such as bagasse, coir–pith, groundnut shell and casuarina leaves to study their thermal behaviour. Analysis is put through in an inert nitrogen atmosphere from ambient temperature to 800°C at a heating rate of 10°C/min. Three reaction zones corresponding to dehydration, hemicellulose–cellulose degradation and lignin degradation are observed for all four biomass samples. The kinetic parameters such as activation energy, pre–exponential factor and order of the reaction for all the components of samples are determined using the simple Arrhenius equation. © 2013 American Institute of Chemical Engineers Environ Prog, 33: 256–266, 2014
