BIO-OIL PRODUCTION VIA FAST PYROLYSIS: PRODUCT YIELDS AND COMPOSITION
Corncob has been investigated as an alternative feedstock to obtain fuels and chemicals via pyrolysis in a well-swept fixed-bed reactor. Chemical structure of bio-oil product forming during the process was elucidated. The influence of heating rate and sweeping gas (N2) flow rate on the pyrolysis product yields were investigated. According to the experimental results, maximum bio-oil yield of ％37.8 was obtained at a pyrolysis temperature of 600℃, heating rate of 700℃/min and at sweeping gas flow rate of 200 cm3/ min. The structure of oil was explained in detail by analyzing with gas chromatography/mass spectrometry (GC/MS) method. The pyrolysis oils were found to be chemically highly heterogeneous and contained mainly phenols, carbonyl groups, esters, and nitrogenous compounds. Among these compounds, the most abundant compounds were detected as phenolics in bio-oil. According to these results, corncob bio-oil is a valuable source of chemical raw materials.
