    Abstract: 本研究是將工業區廢水汙泥以熱裂解法進行處理,在無氧環境進行加熱後,汙泥可以分解成低分子的裂解油及不可冷凝氣體。實驗中由常溫加熱至150℃後,每隔一段時間增加100℃,逐步加熱至700℃,加熱至100℃時汙泥會開始進行水脫附,有機物質在500℃完成主要的裂解反應。過程中可取得各裂解溫度區間的液體產物,並收集最後殘餘之固體物,剩餘之固體以灰分和碳為主,可當活性碳做進一步的利用。裂解油之熱值已達到市售油品水準,可將裂解油和市售柴油混合利用,但是裂解過程中所花費之耗能成本更是決定此項裂解機制的效益是否符合市場需求。
    In this study, industrial sludge was treated by pyrolysis. After heating in anaerobic environment, the sludge can be decomposed into low molecular cracking oil and non-condensable gas. In the experiment, after heating from room temperature to 150 ℃, the temperature is increased to 100 ℃, and then gradually heated to 700 ℃. When the temperature is 100 ℃, the desorption of the sludge will begin and the organic material will complete the main cracking reaction at 500 ℃. The process can be obtained in the temperature range of the pyrolysis liquid products, and collect the final residual solids, the remaining solid ash and carbon-based, can be further used when the activated carbon. The caloric value of pyrolysis oil has reached the level of commercial oil, can be used to mix pyrolysis oil and commercial diesel oil, but the cost of energy consumed in the cracking process is to determine whether the effectiveness of the cracking mechanism is in line with market demand.
