Date: 13/12/2022 – 9:00 – Salle des thèses S3 102 Abstract: The work of this thesis falls within the context of automobile depollution, more precisely in the three-way catalysis (TWC) and the oxygen storage capacity measurements (OSC) of the catalysts used in these reactions. During the project, a study on samples of ceria-zirconia oxides is

Date: 16/12/2022 – 9:30 – CNRT conference room Abstract: In the context of energy and economic crisis, the smooth energy transition will require a proper combination of energy efficiency and integration of renewables to achieve the optimum trade- off between the increasing energy demand and environmental commitments according to Paris Agreement. In that context, the

Date: 19/12/2022 – 14:00 – CNRT conference room Abstract: Chabazite (CHA) type zeolite is one of the most promising zeolitic frameworks for CO2 capture and separation due to its large cages and high microscopic flexibility. In this thesis we showed that CHA particle sizes can be tuned by altering the incubation time during the synthesis

Date: 16/12/2022 – 14:30 – CNRT room conference Abstract: Metal-sulfide materials for ethane conversion in presence of CO2 Ethane processing is a large industrial branch for high-valuable chemicals production. Steam cracking of oil fractions is the major process currently used to produce ethylene. An alternative ethane conversion strategy is the oxidative dehydrogenation of ethane with
