The climate change demands reduced emission of CO2 to the atmosphere especially from mobile and stationary sources like fossil fuel fired power plants. The latter have in the near future to perform CO2 capture and deposition and/or change of fuel to CO2 -neutral biomass, alone or combined with e.g. coal. Flue gas from biomass combustion leads however, to a drastic increase of the potassium salt content causing fast deactivation of the V2O5/TiO2 catalyst traditionally imployed in most power plants. Here we report our latest results concerning an alternative deNOx technology utilizing ionic liquids as selective gas absorbers in a possible end-of-pipe installation. Design of effective ionic liquid NO absorbers, the possible absorption mechanism as well as the absorption capacity versus temperature, NO partial pressure and other components of the simulated flue gas will be addressed. The performance of selected systems as Supported Ionic Liquid Phase absorbers will also be highlighted.
