應用微波電漿進行汽車殘渣(ASR)處理之研究
Transforming Automobile Shredder Residue (ASR) into Valuable Byproduct by Microwave Plasma
摘要
報廢車輛受到了世界各國政府的廣泛關注，因為若僅採用掩埋而不進行任何前處理狀況下，它所含有害物質將直接嚴重影響環境和人類健康。報廢車輛 (ELV) 的處置會產生車輛粉碎殘餘物 (ASR) 的異質高分子量廢棄物，熱處理是回收商常用的一種處理方法，但廢棄物混合物中含有氯和金屬，可能會造成焚化爐設備出現問題。 因此，本研究採用微波電漿技術進行ASR處理實驗，利用電漿技術可以將ASR轉化為CH4、H2、CO和CO2等能源氣體。研究結果顯示在25% 碳酸鈣、25% 雞骨、1,000 W 功率和 7 L.min-1 氮氣載氣實驗參數下，合成氣生成可達最佳效率，生成 2.09 % H2、0.92 % CO、0.3 % CH4 和 0.19% CO2合成氣。當使用碳酸鈣和雞骨作為載體時，重金屬去除率和VOCs去除能力可達最大效率。研究數據清楚地指出催化劑具有重大影響，研究採用掃描電子顯微鏡 (SEM)分析，確認材料的表面性能在微波電漿後有所不同；另透過X光繞射儀(XRD)和傅立葉轉換紅外光譜儀 (FTIR)測量，確認 ASR 樣品在微波電漿前後的結晶度。

End-of-life vehicle waste has received a lot of attention from governments all over the world because it contains hazardous wastes that directly affect the environment and people when treated only by landfilling, without any preprocessing. The disposal of end-of-life vehicles (ELVs) produces a heterogeneous high-molecular-weight waste stream of automotive shredder residue (ASR). Heat treatment is one method that has aided recyclers, but the waste mix contains chlorine and metals that may cause problems with standard incinerator equipment. As a result, this study employs microwave plasma technology to conduct ASR experiments, and ASR can be converted into energy gases such as CH4, H2 CO and CO2 using plasma technology. The best efficiency of synthesis gas was synthesized under ideal circumstances using 25% CaCO3, 25% chicken bone, 1000 W of power energy, and 7 L.min-1 of nitrogen carrier gas, precisely 2.09 % H2, 0.92 % CO, 0.3 % CH4, and 0.19 % CO2. When CaCO3 and chicken bone were employed as supports, the capacity of heavy metal removal rates and VOCs removal were likewise maximal. The data clearly suggests that catalysts have a significant impact. SEM analysis was used to confirm that the surface performance of the materials differed following microwave plasma. XRD and FTIR measurements were also used to confirm the crystallinity of the ASR sample before and after microwave plasma.
