discussed in the Chemical Action Theory. According to this theory the action of certain flame and glow retardants is to promote the pyrolysis products when the polymer is subjected to thermal degradation. Ideally the carbon present in cellulose could be
the fact that some inorganic salts, like some painting pigments, can affect the formation of some pyrolysis products or lead to secondary pyrolysis reaction [ 34 , 35 ]: the ability of the powder pigment to influence the pyrolitic behaviour could not
TG–IR was used to further analyze the gas products during the thermal degradation. Figure 4 shows the 3D TG–IR spectrum of gas phase in the thermal degradation of LDPE3 under nitrogen. From this figure, FTIR spectra of all the volatile pyrolysis

of intermediate pyrolysis products with evolvement of CO 2 and H 2 O occurs from 250 to 500 °C, more intensively from sample 1. The decomposition of the residual carbonates or burning of some residual carbon [ 26 ] is followed at temperatures above
two and continues to 500 °C, which corresponds to the secondary decomposition of pyrolysis products derived from the second phase. The volatility behaviour of methyl esters is comparable with that of diesel fuel. Figure 3 depicts a
occurs at higher temperatures when most of thermal decomposition processes are finished. Thus, in gasification process the primary pyrolysis products, condensable and non-condensable vapours and mainly char undergo secondary reactions with gasification
temperature and the extract obtained was analyzed for the content of PAH. The gaseous products of elastomer thermal decomposition were obtained by their pyrolysis performed in glass pyrolytic test-tubes. The pyrolysis products were transferred by means of a
