Abstract
Cost-effective fractionation (pretreatment) of lignocellulosic biomass is necessary to enable its large-scale use as a source of liquid fuels, bio-based materials and bio-derived chemicals.
Highlights
The vast majority of today’s transportation fuels and organic chemicals are derived from fossil resources, mainly from oil
The pretreatment resulted in fractionation of the biomass into the following components: (1) a cellulose rich material, (2) a precipitated lignin and (3) a recovered ionic liquid solution containing a range of solutes
The resulting two materials and the ionic liquid solution were analysed in detail, for the first pass time course and for the recycling experiment
Summary
The vast majority of today’s transportation fuels and organic chemicals are derived from fossil resources, mainly from oil. Compositional analysis of the pulp material confirmed the extraction of lignin and hemicellulose into the ionic liquid solution as the major reason for the mass loss relative to the initial biomass weight.
