Abstract:
Fast pyrolysis is the first step of the bioliq® concept, which is developed at the Karlsruhe Institute of Technology for synthetic fuels production from biomass. In the bioliq® fast pyrolysis plant shredded straw or other types of dry biomass are mixed with a hot heat carrier (sand) in a twin screw mixer reactor with two rotating screws. At a temperature of 500 °C and in the absence of oxygen the biomass particles are rapidly decomposed within seconds and char, pyrolysis gas and liquid condensates are produced. Results of the obtained products of the pyrolysis test campaign in November 2014 are presented. The products were analyzed in detail in regard to their use in the subsequently following gasification step. As product distribution, the liquid products were found to be 61 wt.%, the solids fraction to 21 wt.% and the un-condensable pyrolysis gas to 18 wt.%. The obtained products were analyzed by elemental analysis, Karl Fischer titration, 1HNRM, etc.). From that, a mass balance could be set up. During the last test campaign representative products were obtained. It was found that the water content in the aqueous phase is significantly high which causes a low higher heating value (~ 4 MJ/kg). The used method for the particle size measurement gives a good idea of the particle size distribution but has to be improved. The same applies to the measurement of viscosity for the organic condensate, because the condensate contains particles what makes it difficult to use conventional measurement methods.
