This project aims to combine existing knowledge about the elementary thermal reactions of pyrolysis and combustion which take place simultaneously in the various processes of hydrocarbon oxidation. Particular attention is paid to methane and light hydrocarbons because the degradation of heavy hydrocarbons requires a reasonable knowledge of the elementary reactions involving hydrocarbons and radicals of low molecular weight, which condition the entire chemical evolution of the reagent system. On the basis of experience gained regarding the pyrolytic reactions of hydrocarbons, the process of partial combustion of light hydrocarbons was studied. This was done by completing an existing kinetic diagram by the addition of the elementary kinetic acts, which are significant and important in defining the interactions of radicals and oxygenated compounds. Although containing considerable kinetic simplifications, the diagram which was developed features approximately 60 chemical species and over 1000 elementary reactions. It can describe pyrolysis and partial oxidation, define the limits of ignition and characterise the combustion of light hydrocarbons.
