ELVs (End-of-Vehicles) in Korea incrasease continusely because of increase of used car. Automobile Shredder Residue (ASR) is final product of ELVs (End-of-Vehicles) after recycling. Automobile Shredder Residue are composed of light and heavy fluffs and soil/dust. In this study, 5 ton/day pilot plant of shaft type has been designed and constructed and 15 times of test run were performed. For the stable operation, operation conditions such as the amount of fed ASR and cokes, air flow and temperature in the gasification melting system have been changed and the composition of the produced gas such as $H_2$, CO and $CH_4$ and air pollution compound including dioxin discharged from the stack have been analyzed.

Prior to discuss on recycling status and future prospects for the non-ferrous metals in the Korea, Japan and U.S.A. respectively, worldwide resources of non-ferrous metals and characteristics with recycling of non-ferrous metals are reviewed. In case of recovery non-ferrous metals, recycling of automobile shredder dust and E.A.F. dust are illustrated. Finally, the problems and technological developments associated with recycling of non-ferrous metals are summarized.

폐자동차의 최종처분 과정에서 발생하는 자동차 파쇄 폐기물(Automobile Shredder Dust)은 대부분이 고분자 화합물로 높은 발열량을 가지고 있다. 또한 할로겐족 원소가 포함된 난연성 고분자류가 많아 다이옥신의 생성 우려가 높은 고분자류와 다이옥신 생성의 촉매 역할을 할 수 있는 금속성분이 많이 함유되어 있어 가스화용융시스템에 적용하여 처리하기에 매우 적합한 폐기물이다. 본 연구에서는 ASR의 가스화 용융 시설에서 고농도 CO를 함유한 합성가스를 수성가스전환반응(Water Gas Shift reaction, WGS)을 이용하여 수소의 수율을 높이는 기술을 제시하였다. 가스화 용융 설비에서 배출되는 합성가스 조성을 기준으로 적합한 고정층 WGS 반응기를 설계하고, 고온 촉매(KATALCO 71-5M)와 저온 촉매(KATALCO 83-3X)를 사용하여 실험하였다. 수성가스 반응 후의 가스 조성은 온도가 상승할수록 일산화탄소가 줄어들고 이에 따라 수소와 이산화탄소 발생량이 증가 되어 고온 촉매를 사용했을 경우 일산화탄소 전환율 ($1-CO_{out}/CO_{in}$)은 55.6에서 95.8%까지 상승하였다. 동일한 온도조건에서는 촉매에 관계없이 $CO/H_2$가 감소할수록 전환율도 감소하는 경향을 보였지만 동일한 합성가스 조성에서 일산화탄소 전환율을 비교하면 저온 촉매가 고온 촉매보다 매우 우수함을 알 수 있었다.

Wastes such as shredder dust of disposed vehicles can be decomposed into low calorific flammable gases by Pyrolysis gasification. A stationary electric Power generation using an internal combustion engine fuelled with the waste-pyrolysis gas is an effective way to ease both waste management and energy saving issues. The waste-pyrolysis gas mainly consists of H$_2$, CO, $CO_2$ and $N_2$. The composition and heating value of the gas generated depend on the conversion process and the property of the initial waste. This research analyzed the characteristics of the combustion and the exhaust emissions in a premixed charge spark ignition engine fuelled with several kinds of model gases, which were selected to simulate the pyrolysis-gases of automobile shredder dusts. The influences of the heating value and composition of the fuel were analyzed parametrically. Furthermore, optical analyses of the combustion flame were made to study the influence of the fuel's inert gas on the flame propagation.
