Experimental characterization of gaseous species emitted by the fast pyrolysis of biomass and polyethylene

Valorisation of forestry waste by pyrolysis in an auger reactor

“…The behaviour of CO 2 with temperature can be characterised by a slight increase or even a decrease (Becidan et al, 2007) attributed to the fact that CO 2 is a product of the pyrolysis of cellulose and hemicellulose by a path less favoured by increasing temperature (Shen et al, 2009). The behaviour of CO 2 with temperature can be also explained as the oxidation of CO, which competes with the kinetically favoured oxidation of hydrocarbons into CO. Hydrocarbon formation increases with temperature therefore there will be less oxygen available to produce CO 2 (Ouiminga et al, 2009). In relation to C 2 -C 4 compounds, it can be observed that these concentrations increase with temperature, although they remain relatively constant from 873 K.…”

“…Referring to CO 2 and CO, which are the main gas products depending on the oxygen present in the fuel, while the concentration of CO increases according to temperature, CO 2 concentration keeps almost constant. The behaviour of CO, with an increasing concentration related to temperature can be explained because an increase of C@O bond breakage (Ouiminga et al, 2009). The behaviour of CO 2 with temperature can be characterised by a slight increase or even a decrease (Becidan et al, 2007) attributed to the fact that CO 2 is a product of the pyrolysis of cellulose and hemicellulose by a path less favoured by increasing temperature (Shen et al, 2009).…”

Pyrolysis of Empty Fruit Bunches: Influence of Temperature on the Yields and Composition of Gaseous Product

“…However, in normal circumstances the heating rate is not very pronounced. The major components of the gas mixture produced from the experiment are CO 2 , CO and H 2 (Tihay and Gillard, 2010;Ouiminga et al, 2009). …”

Reductive and oxidative combustion of polyethylene bags: Characterization of carbonaceous and nitrogenous species

“…Since [22][23][24][25][26][27][28], have used this apparatus with this quantification process, for their research works. For qualitative analysis we can say that because of the weak interaction between the molecular gases, the spectrum of a mixture of gases can be considered as a set of pure compound spectra.…”
