A Study on Pyrolysis of Waste Printed Circuit Boards in a Batch Reactor

Abstract:

In this work the pyrolysis of waste printed circuit boards (PCBs) were investigated through TG technology and a quartz tube batch reactor, respectively. The TG analysis results showed that the total mass loss from 30-800^oC for PCB1 and PCB2 were 35.7% and 41.1%, respectively. With the increase of pyrolysis temperature in a batch reactor, gas yield of PCB2 increased, but increasing rate gradually decreased. The gas yield of PCB2 for pyrolysis time of 1min, 5min and 10min at 600 °C were 30.5%, 31.1% and 31.7%, respectively. It is suggested that the better pyrolysis temperature was at the range of 500-600 °C and the optimal pyrolysis time was 1min. The higher gas yield of PCB2 was obtained at air atmosphere than that at nitrogen atmosphere.
