| Abstract: | A bench-scaled experiment was conducted to recycle oil from pyrolyzing waste printed circuit boards of FR-4 type.This paper presents an innovative alkali treatment-adidification-extraction-vacuum distillation method to extract and separate oil,as well as the characterization of the components in the pyrolytic oil using GC-MS,which shows total phenols account for 62.0% in the oil and the best purity obtained is as high as 96.51%. |
| Keywords: | scrap printed circuit boards(PCB) pyrolytic oil penols extraction separation |
