Research on pyrolysis kinetics and products analysis of waste circuit boards

  • 摘要: 在氮气氛围下,利用热重分析(TGA)对废旧电路板(WPCB)非金属粉末进行热解动力学试验,并利用Py-GC∕MS(pyrolysis-gas chromatoraph∕mass spectrum)和TG(thermo gravimetric)∕MS测试手段对热解产物进行分析。结果表明,WPCB粉末热解过程经历水分蒸发、分解和稳定3个阶段,其中分解阶段包含有机质挥发分解和残渣分解2个过程,其表观活化能分别为250.74和23.58 kJ∕mol,指前因子分别为1.35×10 31和3 428.92 min -1。热解产物主要包括苯环取代的芳香族化合物和含溴化合物,此外还包括少量低分子量的碳氢化合物、苯并呋喃等。苯环取代的芳香族化合物主要包括苯、甲苯、乙苯、二甲苯、苯酚、异丙基苯酚;含溴化合物主要包括溴甲烷、溴乙烷、溴苯酚、二溴苯酚、溴化氢。
