CB2G2. Resources & Facilities
The Second generation Biofuel Centre is a Process Development Units (PDUs) to produce 2nd generation biofuels on a pilot scale level as an intermediate step towards the industrial scale-up of these technologies and as a biorefinery test platform. The CB2G constitutes an integrated trial and demonstration platform designed to develop process, equipment and specific components, new biofuels and to apply bio-refinery concepts to biofuels production processes.

• The core of the process equipment is the torrefaction reactor of special design manufactured by LIST AG (www.list.ch):
• It is a cylindrical horizontal reactor with an agitator shaft and attached elements of special design procuring axial transport characteristic for all kind of biomass, radial product homogenisation inside the reactor and excellent heat transfer conditions.
• Reactor heating is carried out indirectly through the hot reactor walls, the actively heated shaft tube and the actively heated internal shaft elements using thermal oil as heat transfer fluid.
