Description du sujet de thèse
The PhD project is part of the PEPR SPLEEN program funded by the French National Research Agency (ANR). The research will be conducted at the Institut de Chimie des Milieux et Matériaux de Poitiers (IC2MP). The objective is to investigate the synthesis of ammonia via non-thermal plasma-assisted catalysis.
Catalytic materials synthesized at UCCS in Lille will be tested in a plasma reactor developed in the laboratory. The active phases of the catalysts will consist of transition metal oxides deposited on supports such as alumina or silica, oxides with a low dielectric constant, making them suitable for plasma-catalysis coupling. These materials will be thoroughly characterized before and after reaction under plasma discharge conditions.
The non-thermal plasma ammonia synthesis reaction will be performed at atmospheric pressure and low temperature (T < 300°C). A parametric study will be carried out to optimize NH₃ yields by investigating reaction temperature, power input, and catalyst nature. The results will be expressed in terms of reactant conversion and ammonia selectivity. Additionally, a kinetic study will be conducted to determine the partial reaction orders with respect to N₂ and H₂, as well as the activation energy of the reaction.
In this PhD project, the candidate will be required to:
• Write a bibliographic report highlighting significant advances in the field of ammonia production under plasma discharge.
• Perform catalytic tests under plasma discharge conditions.
• Analyze and process the obtained data.
Contexte de travail
