摘要
应用热重-红外研究了电路板热解过程的动力学方程和相关产物。在高温流化床惰性气氛条件下热解电路板塑料颗粒,采用元素分析和傅里叶变换红外光谱等方法分析所收集的高沸点液体和固体的性质。结果表明,当温度和气速分别升高时,液体产品的收率也随之升高。热解油主要成分是芳烃,含有苯的取代官能团,热解固体产物主要成分是碳和玻璃纤维。
Pyrolysis behavior and pyrolysis products of the scrap printed circuit boards were investigated using a TG-FrIR analysis system. The fluidized bed reactor was used to pyrolyze the scrap printed circuit boards particles under inert gas conditions, and the liquid products with a high boiling point and the solid products were analyzed using elemental analyzer and FT-IR. It is found that the liquid yield increases with temperature or gas velocity. The main component of liquid products is aromatic compounds with substituted functional group. The solid products mainly consist of carbon and fiberglas.
