COMBUSTION

 

Topics « Combustion » handles all the aspects related to controlled and accidental combustion in :

  • the generation of energy for all kinds of propulsion,
  • the electricity production (thermal power plants, coal combustion, etc.),
  • the use of civil and/or military high energy density materials (HEDM),
  • the energetic conversion of biomass,
  • process safety (in particular the hydrogen risk in the industries),
  • the formation and reduction of pollutants (NOx, PAHs, VOCs, etc.). All the fuels are considered (biofuels, synthetic fuels, metals, etc.).

The basic sciences needed for the treatment of these subjects are chemical thermodynamics, chemical kinetics (both homogeneous and heterogeneous), theoretical thermochemistry among others.

GAS HYDRATES

 

Clathrate hydrates are crystalline supramolecular structures, in which the water molecules form polyhedral patterns defining cavities where various hydrophobic molecules can fit. Gas hydrates are clathrates formed by oil and natural gas components, air components, or hydrogen. They are studied for various reasons...

ORGANIC SYNTHESIS AND SUPRAMOLECULAR CHEMISTRY

 

The group of organic chemistry develop mainly research projects on the chemistry of heterocycles, on isocyanide based multicomponent reactions and on macromolecular chemistry.
The group has acquired an expertise on :

We approach all these fields with a common interest for the developement of new reactions. Ugi adducts have been used in various radical reactions as well as transition metal catalyzed processes. In agreement with the developpement of green chemistry, most of our synthetic approach are analyzed in term of step and atom economy.

The research on supramolecular chemistry mainly focuses on the preparation and use of p-conjugated organic materials. These materials are either prepared for the nanostructuration of 2D and 3D surfaces or for their use as new liquid crystals. These research are organized through a network of physicists of the CEA and IPCMS for the optoelectronic applications.

HYDROGEN NETWORK

 

The Chemical Engineering group is involved in each stages of the hydrogen network such as the production, the storage and the energy recovery. The production is studied thermochemically or from water dissociation by using the biomass gasification process or the iodine/sulfur thermochemical cycles. The storage of the gas is considered in solid form and the technologies studied are the gas hydrates and the storage by adsorption in Organic Frameworks materials type. Concerning the energy recovery, the research activities are essentially focussed on the hydrogen combustion..
