摘要
研究了微波场中低变质煤与塑料共热解时微波功率对焦油组成的影响.利用色谱-质谱联用仪(GC-MS)和傅立叶红外光谱仪(FT-IR)对焦油的组成进行了分析表征.结果表明,随着微波功率的增大,热解焦油呈现出轻质化趋势.当功率由480W增加到800W时,焦油中轻质油含量增加13.2%,重质油含量减少24.2%.焦油中烷烃类物质含量增加4.4%,烯烃含量增加9.1%,而芳香烃类物质含量减少14.6%.因此,微波功率对热解后焦油成分具有重要的影响.
The mixture of low metamorphic coal and plastic is studied under the condition of microwave co-pyrolysis, using FT-IR analysis and GC-MS to characterize the blue-coal and tar, and the effects of microwave power on the tar yield and component are investigated that is focused on. This research shows that with the increase of the microwave power, the tar get more and more cleaner. When the microwave power increased from 480 W to 800 W,the light of oil, alkane and olefins increase by 13.2%, 4.4% and 9.1% in the tar. But the heavy oil and aromatic hydro- carbons decreased by 24.2% and 14.6%. Therefore, microwave power has an important impact on the co-pyrolysis.
