Combined analytical strategies for chemical and physical characterization of tar from torrefaction of olive stone

• A range of complementary analytical techniques can determine composition tars. FT-ICR analysis showed that sulfur and nitrogen in the tar was low. Torrefaction viscosity similar to fossil-based resin binders. be used as a binder road asphalt or biomass briquettes. The advance methodology is critical for progress 1) biorefinery 2) torrefaction product commercialization. chemical characterisation liquid concentrated produced by Arigna Fuels’ pyrolysis plant allowed identification polar, volatile, non-volatile compounds, species containing organically bound sulphur heteroatoms. results suggest only combined use ion chromatography with Fourier Transform Ion Cyclotron Resonance Mass Spectrometry, 1 H- 13 C HS-QC provide comprehensive information on sugar-like material lignin-derived compounds. Due technical robustness short time, Spectrometer found promising tool heavy molecular Importantly from technological standpoint, presence aromatic saturated compounds both samples indicated predominance over products originating cellulose hemicellulose polymers.
