Lignocellulosic biomass is difficult to economically disassemble at high yield due to the presence of highly modified structural carbohydrates and aromatic (lignin) polymers. Papers in this session will discuss recent developments and scale-up in mechanical, chemical, and biochemical pretreatment and fractionation processes – both existing and new approaches (e.g., ionic liquids). Improved measurements and control of pretreatment or fractionation processes will also be part of this topic. We will offer three sessions on this topic centered on the chemistry of the process.
