Microwave Assisted Pyrolysis (MAP) of the plastic fraction of Waste from Electric and Electronic Equipment (WEEE) from end-life computers was run with different absorbers and set-ups in a multimode batch reactor. A large amount of various different liquid fractions (up to 76.6wt%) were formed together with a remarkable reduction of the solid residue (up to 14.2wt%). The liquid fractions were characterized using the following different techniques: FT-IR ATR, H NMR and a quantitative GC-MS analysis. The liquid fractions showed low density and viscosity, together with a high concentration of useful chemicals such as styrene (up to 117.7mg/mL), xylenes (up to 25.6mg/mL for p-xylene) whereas halogenated compounds were absent or present in a very low amounts.
采用多模间歇式反应器，用不同的吸收剂和装置对报废电脑所含的电子电气设备废物（WEEE）中的塑料部分进行微波辅助热解（MAP）。共生成了大量不同的液体馏分（最高可达 76.6wt%），同时固体残渣显著减少（最高可达 14.2wt%）。采用以下不同技术对液体馏分进行了表征：FT-IR ATR、H NMR 和定量 GC-MS 分析。液体馏分的密度和粘度较低，同时含有高浓度的有用化学品，如苯乙烯（最高可达 117.7mg/mL）、二甲苯（对二甲苯最高可达 25.6mg/mL），而卤代化合物要么不存在，要么含量非常低。
