Abstract:
The development of cost-effective lignocellulose based biorefineries requires optimum valorisation of all main biomass constituents, i.e. both sugar polymers and lignin. Most pretreatment technologies, developed to increase the enzymatic hydrolysis of the cellulose fraction for the fermentative production of second generation biofuels or platform chemicals, produce a lignin-rich residue containing minerals and non-converted sugars, which is only suited for heat and power generation. By separating lignin prior to conversion of the cellulose fraction, a high quality lignin may be produced with suitable characteristics for higher-value applications such as the production of phenolics for resins. A pretreatment process that is capable of effective separation of lignin from lignocellulose is the organosolv process [1,2]. ECN is developing an organosolv fractionation technology with the aim to separate all lignocellulose constituents including lignin with sufficient quality for further conversion into fuels and chemicals [2,3].
