Ceramic membranes for gas separation
Our research priorities seek to purify gases (by separation), but also to purify them by associating a processing/reaction step.
 
1-Purification-separation
 
The applications of our developments include:
  • The purification of hydrogen H2, which has applications in many fields:
    • downstream purification of Water Gas Shift reactions
    • fuel cell power supply
    • petrochemical and chemical syntheses: ammonia, methanol...
    • industries: glass, electronics, food, metallurgical, space...
  • The separation of CO2 from gas mixtures, which has major economic and ecological challenges, particularly in the treatment of fumes from coal-fired plants, the most important future energy resource in many countries.
  • The separation of water from organic solvents by gas permeation or pervaporation technologies. 
The main materials studied are: :
  • porous ceramic membranes: zeolites, processed silicas (H2) on alumina, titanium zirconium, macroporous SiC media (MEGA, Mishy, Menoxhy projects)
  • hybrid ceramic-polymer porous membranes (H2, CO2, CO2/N2), for MEGA and NANOGLOWA projects.
  • carbon membranes (H2) (HY2SEPS2 projet)
  • dense ceramic membranes (O2, H2) : perovskites, zirconia… (DEMOYS and CONDOR projets)
 
2-Processing
 
In the field of gas processing, CTI is involved in the development of membrane reactors.

These applications require catalyst impregnation/coating (precious metals or transition metals) to activate the gas processing.
 
Our materials have a high stability at high temperatures (500-1000°C) and chemical resistance enabling development of membrane reactors with high processing yields.
Moreover, the wide variety of geometries achievable (size, shape of the conduits), makes it possible to modify the microstructure (porosity, pore size and shape) and our mastery of impregnation/coating techniques allows optimization of the catalytic membrane reactors for greater efficiency in many applications.
