Study of two promising MOFs, MIL-91(Ti) and MIL-160(Al), for CO2 capture from flue gas

For two decades, the reduction of anthropogenic CO2 emissions from industries has become one of the most crucial issue to combat global warming. Shifting towards a low-carbon economy needs cost-effective novel carbon capture utilization or sequestration (CCUS) solutions. Current benchmark technique, absorption-regeneration amine-based process, suffers from high energy penalties due to solvent regeneration and high environmental impacts. So, adsorption process is widely considered as a promising alternative. In this regard, MOFs as adsorbent offer tremendous potential, owing to their large CO2 adsorption capacity and high CO2 affinity. However, the performances of these materials have rarely been fully evaluated in real industrial conditions. In this context, this study focuses on the determination of performances on two promising MOFs, MIL-91(Ti)1 and MIL-160 (Al)2,3 in conditions close to real industrial conditions (presence of water, NOx, SOx…) for the purpose of being used in a post-combustion capture process based on a Vacuum Pressure Swing Adsorption (VPSA) process.
