ABSTRACT
This chapter discusses extraction of bio-oil-derived chemicals by Ionic liquid (IL) where hydrogen bonding of imidazolium-[Tf2N]-based ILs will be modelled by COSMO-SAC theory. On the basis of the COSMO framework, Lin and Sandler (2002) derived the variation of this model to accommodate nonideality in phase equilibria calculation and predict activity coefficients. In COSMO-SAC, the activity coefficients are calculated segmentwise and the chemical potential of each molecule is determined by summing up contributions of every segment. The electrostatic contribution originates due to the electrostatic interaction between solute and solvent. One of the applications where the hydrogen bonding is put to test can be aqueous-based systems. On a similar line, lignocellulosic biomass has received a great attention as a renewable energy resource as they can improve energy security and reduce carbon emissions. The last decade saw considerable research in the fast pyrolysis process for the production of liquid fuel and chemicals from biomass.
