Conteúdo: | Residual wood fines were used as raw material to produce fast pyrolysis bio-oil in a pilot plant for furtherutilization as antifungal and hydrophobic agent for wood protection. Phenolic compounds derived fromlignin mostly composed the obtained bio-oil. Pinewood was impregnated with natural and diluted bio-oilaiming three different final loads. Scanning electron microscopy images revealed that the internal surfaceof the tracheids was coated by the bio-oil. Fourier-transformed infrared analysis showed no chemicalreactions between wood and bio-oil, while thermogravimetric studies stated changes in the thermalstability of the impregnated pinewood. The bio-oil impregnation proved to be effective to decrease thewater absorption and wettability of the pinewood. In addition, the bio-oil impregnated pinewood withlow load (7.95%) had decay resistance improved by 2.6 and 4.5 times against T. versicolor and G. trabeumfungi, respectively, meanwhile the highest bio-oil loading (81.3%) inside pinewood caused the mortalityof the whole fungal colony in the first days of test.
