Kinetic of thermal decomposition of residues from different kinds of composting

Differences between combustion and oxy-combustion of corn and corn–rape blend using thermogravimetric analysis

“…This behaviour was previously described by the other authors in the literature [48,58] in terms of lignin content. The obtained activation energies are in accordance with the results previously reported for several bioresidues [5,17,24,[30][31][32][33]41,48,50,54,59,60], considering that the oxy-combustion processes generally disfavour chemical reactions. The pre-exponential factors and orders of reaction are in accordance with the previous results [5,[30][31][32][33]54,59,60].…”

“…In this case, Doyle's approximation was used for f(α) [15,16,22,39,[40][41][42], which involves measuring the temperatures corresponding to fixed values of α from experiments at different heating rates [30].…”

Thermogravimetric analysis of biowastes during combustion

“…The Flynn Wall and Ozawa model-free isoconversional method has also been used for the determination of the activation energy associated to the combustion of the SS, AM and OFMS here used, giving slightly higher values than those in this work (140, 143 and 174 kJ/mol, respectively) (Sánchez et al, 2009). This last isoconversional method was used to determine the E corresponding to the combustion of the OFMSW after composting by different dispositions (248, 257 and 259 kJ/mol) (Crespi et al, 2003) and that corresponding to the combustion of different organic solid residues after composting (283 and 258 kJ/mol) (Silva et al, 2004).…”

“…Non-isothermal kinetic methods have been used to study the thermal decomposition kinetics of residual carbonaceous materials such as low rank coal (Kök, 2005), rubber (Moreno et al, 2006), sugarcane bagasse (Ramajo-Escalera et al, 2006), residues from composting (Silva et al, 2004) or urban solid residues composting (Crespi et al, 2003).…”

Characterization of Maturity Level in Laying Hen Manure by Chemical and Thermogravimetric Analysis

“…The first transition, at approx. 124°C, is attributed to residual water removal (free and bound water) from the samples [1,26] . The three transitions in the range 180-600°C, approx.…”
