Abstract

Wood vinegar, a biomass pyrolysis smoke condensed byproduct, was collected in four different temperature ranges: 110–170 °C (WV1), 170–250 °C (WV2), 250–350 °C (WV3) and 350–500 °C (WV4), according to the kinetic stages that characterize it. The chemical properties, organic compounds and concentration of metal ions for each of the fractions were analyzed and the hypothesis evaluated is that the characteristics of each of the fractions are distinct. The organic compounds identified are known valuable compounds in the chemical industries, belonging to the groups of phenols, ketones, acids, alcohols, aldehydes, alkanes, aromatic hydrocarbons and nitrogenous compounds with furan derivatives. In each of the fractions, a high content of specific compounds was identified, and in contrast to the other fractions, no significant difference was found between the organic compounds identified in WV3 and WV4. Each of the fractions contained inorganic elements that are essential for soil fertility.
