Fast pyrolysis of medium-density fiberboard using a fluidized bed reactor

Fast pyrolysis of medium-density fiberboard was carried out using a fluidized-bed reactor under various conditions to find an optimum pyrolysis condition. When the pyrolysis temperature was varied between 425 °C and 575 °C, the maximum bio-oil yield of 52 wt% was obtained at 525 °C. The quality of the bio-oil product increased with increasing pyrolysis temperature. Pyrolysis at a high temperature removed significant amounts of oxygenates and acids, producing more valuable species such as aromatics and phenolics. The main gaseous products were CO and CO₂. The yields of CO and C₁-C₄ hydrocarbons increased with increasing the pyrolysis temperature.
