Parallel and consecutive reactions in fuel gas combustion

Abstract

"The kinetics of the oxidation process of the organic substances known as fuel gas (the alkanes class in general) deals with reactions whose mechanisms are analyzed in many theories and models. Irrespective of the nature and excess of the carburant, all partial combustion intermediates are revealed: alcohols, aldehydes, organic acids (that together with other derivatives from catalytic reforming reactions are characterized by the global parameter VOCs), carbon monoxide and carbon dioxide and finely divided carbon under the form of soot. The volume of oxidation intermediates increases when the carburant excess decreases monotonously to values below the stoichiometric ratio, so that when the limit is reached the carbon dioxide and water vapor volumes can be minimal. This paper puts forward a kinetic combustion model based on the parallel and consecutive reactions producing part of the chemical compounds that form the concentration of VOC, carbon monoxide and finely divided particles of the gas produced by fuel gas combustion."
