摘　　要：在微波加热方式下,采用自行设计的两段式石英反应器考察热解温度和吸波剂的添加对褐煤与棕榈壳共热解特性的影响,利用气相色谱-质谱联用仪和气相色谱仪分别对焦油和热解气体进行分析.结果表明:在褐煤与棕榈壳共热解过程中二者存在明显的协同作用,挥发分产率有明显增加.利用活性炭做吸波剂时,焦油产物有一定的轻质化,且轻气体产物中产生较高含量的CO和H_2.在600℃下,活性炭做吸波剂时,CO和H_2在轻气体中的总产率达到91.98%(体积分数).The lignite and palm kernel shell were co-pyrolyzed using a newly developed two-stage reactor under microwave radiation.The effects of co-pyrolysis temperature and catalyst on co-pyrolysis charactenstics were investigated.The tar and gas from pyrolysis were subsequently analyzed using gas chromatography-mass spectrometry and gas chromatograph respectively.The results show that there is a synergetic effect between lignite and palm kernel shell during microwave co-pyrolysis process.The yield of volatile matter increases compared with the calculated value.When activated carbon is used as the microwave absorbent,it seems to change in the tar composition towards smaller molecular weight products and this significantly promote the high content of H_2 and CO in the gas phase.The total volume fraction of H_2 and CO is 91.98% at 600 ℃.
