N2 - Experimentally, liquefaction of printed circuit board wastes in motor oil at 593 K for 30 minutes generated approximately 73% of oils, 4% of gases, and 23% of copper-rich solid residues. The cuts of the light oils produced from liquefaction of printed circuit board wastes into weighted boiling fraction were primarily naphtha and gas oil. Over 90% of copper in liquefaction residue was recovered. An increase in aromaticity in product oils observed by proton NMR and FTIR spectroscopies was attributed to repolymerization or condensation, to some extent, involved in the liquefaction process.
