The experiments were performed in a fixed bed reactor at 500 ºC. The highest hydrocarbon yield (53.5 %wt.) was obtained with the conditioned liquid. The coke yields were significant in all the cases, from 9 to 14 %wt. The synthetic bio-oil produced lesser hydrocarbons and more oxygenated compounds and coke than the authentic feedstocks from biomass. The previous thermal treatment of the raw bio-oil had the positive effects of increasing 25 % the yield of hydrocarbons, decreasing 55 % the yield of oxygenated compounds and decreasing 20 % the yield of coke, particularly the more condensed coke.
