چکیده انگلیسی
Fourier transform infrared (FTIR) spectroscopy, combined to principal components analysis (PCA), was applied in the classification of biomasses through the composition of their bio-oil. Bio-oils were produced through pyrolysis in a bed fixed reactor, using fifteen biomass sources available in Brazil and its characterization was made using gas chromatography coupled to mass spectrometric detector (GC/qMS). Around two hundred compounds were tentatively identified in the fifteen bio-oil samples. As expected, the chemical compositions in each bio-oil were distinct. Through the chromatographic information and PCA of the FTIR spectra it was possible observed the similarity and dissimilarity of biomasses according their bio-oil compositions. PCA revealed that FTIR spectra of biomasses fell into three different groups representing distinct bio-oil chemical compositions. The biomasses that belong to group 1 showed bio-oil compositions rich in carboxylic acids, the group 2 showed bio-oil compositions consisting predominantly of phenols and group 3 showed bio-oils with a significant amount of nitrogen compounds. Such clustering information allow exploring bio-oil quality prior to pyrolysis process.
