     fractions of waste square timber and waste ordinary plywood were pyrolyzed in a pyrolysis plant equipped with a fluidized bed reactor and a dual char separation system. the maximum bio-oil yield of about 65 wt.% was obtained at reaction temperatures of 450–500 °c for both feed materials. for quantitative analysis of bio-oil, the relative response factor (rrf) of each component was calculated using an effective carbon number (ecn) that was multiplied by the peak area of each component detected by a gc-fid. the predominant compounds in the bio-oils were methyl acetate, acids, hydroxyacetone, furfural, non-aromatic ketones, levoglucosan and phenolic compounds. the wop-derived bio-oil showed it to have relatively high nitrogen content. increasing the reaction temperature was shown to have little effect on nitrogen removal. the ash and solid contents of both bio-oils were below 0.1 wt.% due to the excellent performance of the char separation system.
