The generated pyrolysis vapor was condensed by three-stage coolingquench with coolant at the first stagewater cooling with shell-and-tube heat exchanger at the second stageand ice bath cooling at the last stage. The liquids obtained from each stage were named biooil 1bio-oil 2 and bio-oil 3correspondingly. It was found that with the addition of CaO to pinethe water content in bio-oils increased the heating value decreasedthe ph increasedthe content of ketones and hydrocarbons increased while phenols decreased. The bio-oils stability tests showed that phenols content increased increased to 50 % when 30 % of CaO is added esters decreased and the water content increased after the bio-oils stored for 30 days at room temperature.
