Cleaner Fossil Energy and Carbon Capture Technologies Research Group

The Group has an international reputation for research focussing on developing solid adsorbents for post-combustion capture (PCC) where both activated carbons (ACs) and supported amines have the potential to reduce regeneration energies considerably lower than for advanced amine systems.

 

Prof Colin Snape

Carbon Dioxide Capture

 
 

There is extensive international collaboration, including the Chinese Academy of Sciences with whom the carbon bead adsorbents have been jointly developed and the Korean Institute of Energy Research who are testing 100 kg quantities of adsorbents prepared at Nottingham.

Other research covers fundamental aspects of oxyfuel combustion, including circulating fluidised beds. Further, Nottingham is one of the core partners in the UK CCS Research Centre.  Further, the adsorbents developed has also bene used for multi-pollutant control, including mercury.
