摘要(Abstract)：

在500℃下,进行了废线路板环氧树脂粉末与Fe系、Ca系和Al系三类氧化物的真空共热解脱溴试验。通过离子色谱分析和氧弹燃烧法,研究了不同氧化物对固、液、气三相热解产物中有机溴和无机溴分布的影响。试验结果表明,Fe系和Ca系氧化物能显著降低热解液体中的溴含量,大部分的溴残留在固相中。其中以Fe3O4和CaCO3的脱溴效果最好,热解液体中的溴分布率从没有添加时的72.10%分别降到8.91%和7.69%,分别有78.74%和90.84%的溴以无机溴的形态残留在热解渣中,有机溴转化为无机溴的效率从没有添加时的46.42%分别提高到82.25%和92.13%。Al系氧化物能明显增加热解液体中的水分含量,原料中的溴绝大部分转移到液相中,包括油相中的有机溴和水相中的无机溴。Fe系和Ca系氧化物的脱溴效果优于Al系氧化物。用GC/MS分析测定了油相中含溴化合物的种类和相对含量。
