1.2 Formation and reduction of pollutants from combustion

Autres activités de recherche du groupe I :

1.1 : Détermination des paramètres fondamentaux

1.3 : New fuels

1.4 : New combustion technologies for energy production

Combustion of fuels generates pollutants. Many efforts have been devoted to understand the mechanisms of formation of pollutants (nitrogen oxides, polyaromatic hydrocarbons, soot) and to propose means to reduce their formation. ICARE has been very much involved in these studies.

1.2.1 Chemical kinetics of NOx formation and destruction

Nitrogen oxides (NOx) are important pollutants formed during combustion in air. Nitric oxide (NO) is generally the most important. In collaboration with the Ecole des Mines at Albi, we have studied the reduction of NO by solid fuels (ACL35). Our kinetic models have been extended to conditions relevant to a cement plant calciner. This work showed the importance of nitrogen and sulphur mass fractions in the fuel on the formation/reduction of NOx. Among the intermediates formed during the (...)

1.2.2 Soot and precursors

1.2.2.1 Formation of PAH and soot precursors Soot is still one of the most difficult combustion generated pollutant to reduce. The formation of soot precursors (benzene, cyclopentadiene, PAH) was studied in a JSR and a chemical kinetic modelling was performed within a research program of ESA-MAP "ombustion Properties of Materials for Space Applications Phase 2 (2005-2012) in collaboration with LCD in Poitiers, the Universities of Lund and Cottbus. Analytical procedures involving (...)
