Stage Chimie Hauts-de-Seine entre avril et septembre 2023 5 mois
IFP Energies nouvelles (IFPEN) est un acteur majeur de la recherche et de la formation dans les domaines de l’énergie, du transport et de l’environnement. De la recherche à l’industrie, l’innovation technologique est au cœur de son action, articulée autour de quatre priorités stratégiques : Mobilité Durable, Energies Nouvelles, Climat / Environnement / Economie circulaire et Hydrocarbures Responsables.
Dans le cadre de la mission d’intérêt général confiée par les pouvoirs publics, IFPEN concentre ses efforts sur :
Context
Ammonia is considered as a good hydrogen and energy carrier, and a promising solution for de-carbonization. However, the poor combustion characteristics of ammonia (e.g., high ignition energy, low flame speeds, and limited flammability) are obstructing it from becoming a feasible solution. Therefore, various technologies have been developed to boost ammonia combustion, such as blending of hydrogen, methane, diesel, and additives. Although these technologies show different boosting capabilities, they also impose new challenges such as higher NOx emissions and introduction of CO2 emissions.
One potential way is through the using of NOx as boosting additives. Comparing to other additives, it is easy to obtain (abundant in the exhaust gas from the combustion of NH3 and NH3/H2 mixtures) and could boost the combustion without introducing CO2 emissions. The main composition of NOx is mainly NO with NO2, and N2O. NO2 is known the have high reactivity and could boost combustion through a "NO2-NO" loop which generates OH radicals. Although NO is typically considered to be much less reactive, a recent study on the impact of NOx addition on methane combustion found that NO acts as an inhibitor on ignition at low concentrations but become a promoter as NO concentrations increase in the mixture. These indicates that boosting ammonia combustion with NOx addition could be of great potential.
