PAACS activities focused on the design and optimization of new catalyst structures to improve heat and material transfers in fixed beds (gas / liquid). It was also aimed at developing new production processes of existing catalyst materials in architecture and microstructure controlled via nanotechnologies. The two main industrial applications concerned were industrial gas production processes and derivatives and of automobile exhaust post treatment systems.
Its main objectives were in particular:
- strong technological and strategic differentiation compared to the concurrence and catalyst manufacturers,
- societal and environmental benefits (improved air quality)
- better management of raw materials (precious metals)
- reduced overall costs.
During the project, different types of stacks were experimentally characterized by hydraulic studies (pressure drop, axial and radial dispersion in the bed) and bed topology studies by image analysis (porosity, orientations, etc.)
This project was the subject of several publications and resulted in the filing of 3 patents.
