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

Abstract

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 CO 2. The yields of CO and C 1 -C 4 hydrocarbons increased with increasing the pyrolysis temperature.
