초록

There have been a lot of efforts to increase recycling rate by more utilization of end of life vehicles (ELVs) in Korea.
The target of recycling rate was set to 85% until 2014 and 95% after 2015 with including up to 10% of energy recovery, according to the law of “regulation about resource recycling of electrical and electronic products and automobiles”.
Therefore, to achieve 95% of recycling rate by the year of 2015, the automobile and recycling industries should develop an innovative technology to treat automobile shredder residues (ASRs) by efficient means of reduction or conversion to energy, which were generated as final left-over after recovering all the valuables from ELVs. As one of the options to convert to energy forms, the gasification of them was proposed. In this study the gasification experiment was performed using ASRs at fixed-bed reactor with a capacity of 1 kg/hr, at different temperatures of 800, 1,000 and 1,200oC, and at equivalence air ratios ranging from 0.1 to 0.5. The syngas (H2 + CO) yield from ASR gasification experiment was obtained up to 86% in maximum and about 40% in minimum in the experimental conditions given. There was a trend that the amount of syngas increased with elevated temperatures and the calorific value also showed similar trend with syngas production.
