Objectif
One of the technological problems that faces society today is the environmentally friendly and economically favourable separation, capture and storage of gases. Here, CO2 that will be critically important in the future European H2 based economy. It is crucial to find a new route to capture and store CO2 produced during various industrial processes with different conditions. The present project aims to initiate novel synthesis strategies for adsorbents with specific properties with respect to gases, notably carbon dioxide, and operating conditions of industrial processes.
Five aspects are tackled along the project:
- what are the most appropriate building block for an adsorbent
- what are the best pore sizes and architectures
- how do adsorption properties agree with those predicted from calculations obtained for materials designed from the two first points.
- what are the industrial prospects in terms of the scale-up of the synthesis of the novel adsorbents pinpointed above
- how does the adsorbent behave with respect to specific applications involving environmentally sensitive gases.
The basic building blocks required for adsorbent synthesis will be investigated with respect to gas interactions. Such groups will include metals, cations, silicon/aluminium wall ratio and organic ligands. After choosing a zeolite benchmark, the project will concentrate on the synthesis of two families of nanoporous materials: periodic mesoporous oxides and metal organic frameworks. An experimental/modelling approach will be followed to search the most suitable materials with the most appropriate building blocks, pore size and architecture.
The materials will be characterised by adsorption of carbon dioxide and tested under industrial conditions. Several materials will be studied for synthesis up-scale. A test application of CO2 elimination during H2 production from Syngas will be investigated before providing a generic modelling tool to select adsorbents for further applications.
