| Abstract: | Pyrolysis as an alternative for recycling waste retarded material was studied.To obtain thermal decomposition behavior,the experiment with printed circuit board as sample,was done using thermogravimetric analyzer and pyrolysis gas chromatography-mass spectrometry(PY-GC-MS)under N2 atmosphere.Results indicated that average activation energy was 182.294 kJ/mol,pre-exponential factor was 3.07×1011s-1,initial reaction temperature was in the range of 580 K~600 K and reaction range increased with the temperature.Temperature has no significant influence on the products and a little bit more small molecules volatile substances produced when it was above 673 K.The pyrolysis products contained high concentration of phenol,brom-phenol,as well as bisphenol A,tetrabromobisphenol A,methyl phenols,C1-C4 alkanes and alkanes. |
