    摘要: 本研究探討藉感應加熱技術熱解處理生
    物污泥轉化國內大宗食品加工業所產生之生
    物污泥為生質燃油之可行性;藉由控制快速
    熱裂解反應爐的停留溫度、升溫速率和停留
    時間等三個主要操作條件,在輔以樣品粒徑
    大小為0.5mm 及冷凝收集溫度為-10℃的試
    驗條件下,來求取生質燃油的最佳產率。研
    究結果顯示,操作條件對於生質燃油產率皆
    有所影響;三種生物污泥的最高焦油產率可
    達25-30%左右。
    對冷凝收集的生質焦油產物做其物理和
    化學特性分析,包括熱值、水份、主要元素、
    pH 值、傅利葉紅外線光譜(FTIR)及氣相層析
    質譜(GC-MS),顯示所得之產物熱值偏低、
    呈現酸性、含氧量偏高,與其他生質廢棄物
    之結果類似,但所含多環芳香族碳氫化合物
    (PAHs)則低於農業廢棄物之結果,若要實際
    運用所得生質焦油,則須進一步去除所含水
    份,以提昇(upgrading)其熱值。
    The objective of the research was to study
    fast pyrolysis with using induction-heating for
    manufacturing the bio-fuel from the
    food-processing wastes. Under the conditions
    of controlling holding temperature, heating rate,
    and hold time, the optimal yield of bio-oil was
    approached in the present study. The
    experimental results showed that these
    operating parameters had significant effect on
    the yield of bio-oil, which could be obtained at
    the percentage yield of 25-35% from three
    bio-sludges.
    The physical and chemical of bio-oil
    collected from the cryogenic condensation
    were further conducted, including heating
    value, elemental analysis, pH value, Fourier
    Transform infrared (FTIR) and gas
    chromatograph-mass spectroscope (GC-MS).
    The characteristics of resulting bio-oils showed
    to be high contents of water and oxygenated
    components, resulting in low pH and low
    heating values. The results were very similar to
    bio-oils obtained from other biomass materials.
    The contents of polycyclic aromatic
    hydrocarbons (PAHs) in the bio-oils, however,
    were significantly lower than those from
    agricultural wastes. Therefore, the bio-oil
    should be further upgraded to increase its
    heating value by the removal of water while it
    was practically used as bio-fuel.
