利用热解法处理回收废线路板被认为是目前废线路板回收工艺中最具有前景的一项技术.其中废线路板热解后的有机高分子热解油具有潜在的利用价值.但是热解油成分比较复杂,导致了废线路板热解工艺没有得到大规模的工业化应用.通过对成分复杂的热解油进行常压实沸点蒸馏将热解油切割成不同温度段的馏分,再对不同馏分进行分析检测.分析发现,热解油各馏分主要以碳氢化合物为主,其中碳含量均在50%以上;热解油中以苯酚、4-异丙基苯酚、2-异丙基苯酚等苯酚类物质为主,含量超过600;热解油IR检测含有CH2、CH-OH等特征峰;另外热解油中还检测出含溴苯酚类有机物,含量在10%以下.对热解油各馏分进行成分分析,为废线路板热解的机理研究及热解油的资源化利用提供基础数据和理论依据.
