Étude cinétique de la pyrolyse en phase gazeuse de molécules organiques contenant des hétéroatomes représentatives de composés toxiques présents dans les sols pollués

Abstract : The pyrolysis of seven surrogates of toxic compounds (diethyl ether, bromoethane, methyl chloroacetate, nitromethane, isopropyl nitrate, diethylamine and chlorobenzene) was studied during the thesis in two different types of reactors at the laboratory scale: a silica jet-stirred reactor (JSR) and an alumina tubular reactor (TR) to carry out studies at temperatures above 1200 K. Axial temperature profiles were measured and were used to take into account the temperature gradient in the TR. In addition to gas chromatography, a new analytical technique for our laboratory was used: The Fourier Transform InfraRed Spectroscopy (FTIR), for which an analysis method has been developed. As part of the study, detailed kinetics models were developed except for the diethylamine. Overall, these kinetics models well predict the reactivity temperature dependence and the formation of the major products determined experimentally. Since there is a lack of kinetic data in the literature for the pyrolysis and oxidation of brominated, chlorinated and nitrogen compounds, many kinetic parameters were estimated in most of the kinetic models developed
