    摘要註: 本論文主要探討廢棄物中之銅及鋅在不同氣化條件下對產氣率與產氣組成之影響,主要以配製不同組成之人工模擬廢棄物,在不同操作操作溫度與ER值條件下,經流體化床操作,評估銅及鋅對於氣化之影響,作為廢棄物氣化程序操作之參考。由於銅和鋅為廢棄物中含量較豐富之重金屬,因此將探討此兩種重金屬應用於氣化技術之可行性,同時亦能將廢棄物轉化為生質能以達到廢棄物資源化的目標。由本研究結果顯示,操作溫度800oC,ER值0.3條件下,單一添加銅0.3 wt%以上或添加鋅0.1 wt%以上,可以增加合成氣H2的莫耳百分率並同時降低 CO2的莫耳百分率。但總熱值會降低,產氣率沒有明顯的變化,對於H2產量可以增加;相較未添加重金屬之H2產量,添加Cu可增加H2產量34.48%,添加Zn可以增加H2產量41.38%。同時添加銅和鋅,較未添加的控制組H2的莫耳百分率增加, CO2的莫耳百分率減少,總熱值降低,產氣率沒有明顯的變化。在操作溫度800oC,ER (Equivalence ratio)值0.3操作條件下,以濃度0.1wt%混合添加銅和鋅的效果最佳,可以彌補單一添加銅的低H2的莫耳百分率以及單一添加鋅的產氣低熱值,且具有最高的H2產量。由本研究結果顯示同時添加Cu和Zn濃度0.1 wt%,操作溫度800oC,ER值為0.3時為最佳操作條件。 The study investigates the effect of Cu and Zn on artificial waste gasification. The experiments were carried out in a bubbling fluidized bed gasifier by using artificial waste. The operating parameters included operating temperature and ER (Equivalence ratio). Due to Cu and Zn are the kinds of heavy metal abundant in waste, we want to know the feasibility of applied in gasification technology. The goal of waste resource as biomass will be achieved at same time. The results show that the H2 mole percent and H2 production are better among those for adding Cu0.3 wt% and Zn0.1 wt% operated at 800oC, ER0.3. But in those cases, LHV is low and gas yield is not changed significantly. To compare with non-addition metal experiment, adding Cu could promote H2 production more than 34.48% and adding Zn could promote H2 production more than 41.38%. The co-addition of Cu and Zn could increase H2 mole percent and H2 production, decrease CO2 mole percent and LHV, no significant change with gas yield. At operating temperature 800oC, ER0.3, co-addition of Cu and Zn at 0.1 wt% has better result with H2 production and Zn with LHV. The optimal operating parameter in our study is co-addition of Cu and Zn with 0.1 wt%, operating temperature is 800oC and ER is 0.3.
