The Compounds Study of Waste PC Main-Board pyrolysis

摘要

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:l) 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.
