Description
The advance in analytical methodology is critical for progress in 1) biorefinery and 2) torrefaction product
commercialization. The chemical characterisation of torrefaction liquid and concentrated tar produced by Arigna
Fuels’ pyrolysis plant allowed identification of polar, volatile, non-volatile compounds, species containing
organically bound sulphur and nitrogen heteroatoms. The results suggest that only combined use of ion chromatography
with Fourier Transform Ion Cyclotron Resonance Mass Spectrometry, and 1H-13C HS-QC can provide
comprehensive information on sugar-like material and lignin-derived compounds. Due to the technical robustness
and short analysis time, Fourier Transform Ion Cyclotron Resonance Mass Spectrometer was found to be a
promising tool for tar analysis containing heavy molecular compounds. Importantly from a technological
standpoint, the presence of aromatic and saturated compounds in both liquid and concentrated tar samples
indicated the predominance of lignin-derived compounds over products originating from cellulose and hemicellulose
polymers.
