Group has developed thermal separation techniques (slow pyrolysis) for commercially exploitable components of wood, sufficient for research purposes as well as for application testing. At the moment, there are two instruments with full computer control including fractioned liquid collection: 1) batch type (3 kg scale) and 2) mobile continuous-type (30 kg/h) SP instruments. Biochar and liquids can be processed from low value wood biomass using this equipment. The composition of pyrolysis liquids and biochar are analyzed by several complementary methods. The most common techniques are elemental analyses, gas (GC) and liquid chromatography (HPLC), mass spectrometry (MS), NMR and Fourier transform infrared spectroscopy (FTIR), as well as structural and compositional characterization with modern electron microscopy (SEM and TEM) techniques.

Due to the extreme multidisciplinary nature of biorefining research, a large collaboration network is necessary to reach the ambitious goals set for projects.

Our current projects include

  • wood distillates and modifications for coating purposes
  • wood distillate fractions for antibacterial, antifungal and antimicrobial applications
  • modified biochar for filtration and fertilizers
  • distillates and biochar from different types of biomass and side streams
