Abstract :In this study, aliphatic compounds obtained by pyrolysis of sunflower-extracted bagasse were characterized by column chromatography method. The pyrolysis liquid product was separated into two fractions using pentane: pentane-soluble (aliphatic, aromatic, polar fractions) and insoluble (asphaltic) compounds. The chemical composition of the aliphatic fraction was investigated using chromatographic and spectroscopic techniques (FTIR, column chromatography and GC). According to column chromatography results, pyrolysis oil consists of 52 % aliphatic, aromatic, polar fractions and 48 % asphalten. Column chromatography indicated that the pyrolysis liquid product consists of 8,58 % aliphatic, 19,76 % aromatic and 23,66 % polar fractions. Furthermore, it was shown that the aliphatic compounds mixtures (including from C23 to C31) could be separated into their compounds by the column chromatography method. Chemical characterization of the pentane soluble fraction obtained from the pyrolysis of sunflower extraction bagasse indicated that the pentane soluble fraction could be a raw material source for aliphatic chemicals. The aliphatic compounds obtained by this method can be considered to be a useful alternative to diesel fuels because their carbon distribution is similar to that of diesel fuels.
