Conference paper


Liquid biofuel was obtained by solvolytic liquefaction of lignocellulosic (LC) biomass in glycerol. Different types of wood, reaction temperatures and homogeneous catalysts were tested to obtain solvolytic oil with suitable fuel properties. Liquefaction conditions have little effect on fuel properties, so the upgrade step had to be introduced. Feasibility of hydrodeoxygenation (HDO) upgrading method using commercially available Ni, NiMo and Pd catalysts was investigated under elevated pressure and temperatures between 200 and 325 °C.
