LIGNOCELLULOSIC BIOMASS CONVERSION

摘要

The present invention relates to a process for the production of second generation biofuels and/or sugar based chemicals - for example ethanol, butanol etc - and/or materials - for example plastics, single cell proteins etc. - together with sulfonated lignin from lignocellulosic biomass, in particular from lignocellulosic biomass comprising, among others, annual plants, agricultural waste, or wood. In particular, the present invention relates to a process for the production of sugar based chemicals, biofuels or materials together with sulfonated lignin from lignocellulosic biomass comprising the pretreatment of a lignocellulosic biomass in a sulfite cooking step.
