Developing neoteric ionic liquids for enhancing biomass gasification to produce purified bio-syngas
(NEOBIOSYN) • Design and synthesize novel ILs combined with functionalization and
cosolvent-addition. • Study the biomass preprocessing to provide less recalcitrant and more
suitable raw material for the gasification • Testing gasification performance with pretreated biomass and characterize
gasification performance at different operating conditions • Testing the absorption capacity/selectivity and absorption/desorption rate

Hydrated Ionic Liquids and Their Mixtures: From Chemical Storage and CO2MICALS to Processing of Biomacromolecules
• Develop new hydrated ionic liquids, their mixtures (MIXILs), thus IL-brine systems; • Characterize properties to provide understanding on the underlying mechanisms
and modeling properties for design of MIXILs as an ‘enabler’ technology in CO2 capture;
• Utilize hydrated IL and MIXIL systems in a) dissolution of biomacromolecules; b) CO2 capture and conversion and c) chemical energy storage by facilitating the synthesis of CO2 derived chemicals and fuels;
• Synthesize (industrially) important CO2-derived chemicals and biomacromolecule derivatives via processing of cellulosic biomass and study of protein/enzyme systems in hydrated IL environments.
