Abstract:
Liquid biofuels hold the potential to assist the transition to a bio-based economy and there is an increasing interest to move away from 1st generation to 2nd generation bioethanol due to both ethical issues and feedstock price and availability. The structure of lignocellulosic, however, represents a drawback to the production of bioethanol due to its recalcitrant structure. The objective of this study was to evaluate two processing routes for biomass fractionation and cellulose purification from Miscanthus x giganteus applying subcritical water (SBW) and a modified organosolv method for lignin/hemicellulose extraction. Purified cellulose fibres obtained from Miscanthus were hydrolysed in SBW at 250°C and residence times ranging from 0-40min. Hydrolysis of cellulose derived from sequential SBW mediated extraction resulted in higher yields of glucose
