摘要
采用微波加热技术对低变质煤与油页岩的共热解特性进行探讨,研究了不同配比混合物的热解产物产率及成分,并通过气相色谱-质谱(GC-MS)联用技术对液体产物的成分进行了分析.结果表明:微波热解过程中,适当配入低变质煤可提高焦油产率,增加热解气中可燃气体CO,CH4及H2的含量;微波热解共混物所得焦油成分主要是烃类(约50%～80%),其中烷烃和芳香烃居多(约40%～50%左右),其次是少量的以苯酚类为主的含氧化合物,而并未检测出含氮化合物,这一组成有利于焦油的进一步加氢处理.
This research mainly explored co-pyrolysis characteristics between low meta- morphic coal and oil shale under microwave irradiation, discussed the yield and composition of copyrolysis product, and analyzed components of liquid products by gas chromatography-mass spec- trometry （GC-MS） combined with techniques. The results show that appropriately add low meta- morphic coal to oil shale can improve the yield of tar and increase the content of flammable gas- CO, CH4 and H2. Tar is composed mainly of hydrocarbons （about 50%-80%） in which some hydrocarbons such as alkanes and aromatic hydrocarbons are majority （about 40 %-50 %）, and secondly of less oxygenated compounds with phenol-based and none of nitrogen compounds.
