The Compounds Study of Waste PC Main-Board Pyrolysis

This paper has an explicit exposition on the study of waste PC-Main Board recycling by pyrolysis approach. The decomposing of PC-Main Board is completed above 400°C. For PC main boards around 77% solid residual (pyro-solid), 9 % pyro-oil and 14% pyro-gas were produced after the pyrolysis.The volatile detected by gas chromatography-mass spectrometry (PY-GC-MS) and the results indicated that:1) No significant influence of temperature on the products were observed over 400°C, only with the increase of temperature the small molecules volatile substance became a little high. 2) The characteristic pyrolysis products contained high concentrations of phenol, brom- phenol, while bisphenol A, tetrabromobisphenol A, methyl phenols, C1-C4 alkanes and alkanes were present.
