Bio-oils and chars obtained during pyrolysis carried out in a horizontal rotary oven at 500°C under argon flow and the heating rate of 20°C min"1 from pine wood sawdust, polystyrene and 9:1,3:1, 1:1 (w/w) wood/polystyrene mixtures were investigated in view of their application as fuels. The composition of the blend strongly influences the yield and basic properties of pyrolysis products. The higher proportion of polystyrene in the blend, the higher yield of bio-oil and the lower yield ofcharwas observed. The polystyrene addition to pine wood clearly reduces the amount of pyrolytic water in liquid products. All resulted chars are characterized with similar heating value higher than 31 MJ kg'1. Moreover, it was found that ultimate compositions of chars do not significantly depend on the polystyrene addition to biomass in starting blends. Although the visible increase of carbon content and the decrease of oxygen content is observed, the change is not distinct. On the contrary, the carbon and oxygen content as well as the physicochemical properties of oils are strongly influenced by the blend composition but do not change additively. The addition of polystyrene to pine wood sawdust clearly improves the fuel quality, i.e. pour point, viscosity, total acid number and high heating value. The influence of water removal from bio-oils on their physicochemical properties was also determined. Although it was found that water removal from bio-oil gives product with better properties, bio-oils need improvement of chemical structure to meet requirements for fuels.
