In this study the gravimetric tars produced during torrefaction of Corresponding author.E-mail spruce are analyzed and their condensation behaviour at different temperatures is experimentally investigated and modelled. To the knowledge of the authors, tar condensation has so far been investigated only for the volatiles of pyrolysis, but not yet for the tars of a torrgas. The employed experimental setup is described in Section 2, the characterization of gravimetric tars is shown in Section 3 and the condensation experiments and model are described in Section 4. Finally, the conclusions are exposed.
