“…The biochemical route refers to hydrolysis of cellulosic and hemicellulosic parts of biomass into sugars and subsequently converting these into alcohols, usually ethanol, which can be used as fuel or fuel component (see the recent reviews by Virkajärvi et al, 2009, Dwivedi et al, 2009. (Rudie, 2008) Recently, in Norway, Xynergo has initiated collaboration with CHOREN, and is planning to proceed with pyrolysis. The thermochemical processes are typically based on either gasification of biomass to synthesis gas and subsequently converting the purified gasification gas to liquid products (biomass-to-liquids, BTL), or pyrolysis of biomass into bio-oil, which is subsequent upgraded into fuel grade products.…”
