Hydrophobic behavior of pyrolysis oils obtained by pyrolysis of Scots pine wood (Pinus sylvestris L.) by using extruder type pyrolyzer at 450, 550 and 600 ºC was the objective of the study. Sapwood specimens (15×25×50 mm along the grain) were impregnated with the obtained pyrolysis oils by full- and empty cell treatment. The results indicated that wood impregnated with the studied pyrolysis oils has significantly lower water absorption values than that of the control group. Promising results were found about the anti swelling efficacy of the oils, being in the range of 60-90%. No significantly difference was found in the hydrophobic characteristic of wood samples treated by full- and empty cell process even though the oil uptake of samples treated with full cell process was significantly higher than that of the empty cell process.
