Characteristics of Bio-oil of Forest Products Waste by Fast Pyrolysis Made Process

Petroleum consumption is increasing, while the supply is continuously depleted. Currently, the alternative biofuel such as bioethanol, biodiesel and bio-oil have been developing from various natural sources, including forest product's waste. This paper studies the characteristic of bio-oil made of wastes from forest industries by fast pyrolysis process. Mahogany wood powder, bark and paper sludge were heated in the temperatures of 400oC, 450oC, 500oC, and 550oC to produce bio-oil. Results show that bio-oil can be produced from all three materials studied. Mahogany wood powder which was heated at 550oC produces the highest liquid yield of 25%, yields of bio-oil is 5 %, phenol 3.66%, pH 2.98, specific gravity 1.092 g/cm3, heating value 9,28 MJ/kg. The fast pyrolysis process produces bio-oil which is predominantly composed of acetic acid and phenols.
