| 摘 要： | 进行了微波加热条件下陕北孙家岔低变质煤与塑料共热解的实验研究.结果表明:随着塑料添加比例的增大,兰炭产率逐渐降低,焦油产率明显提高.当塑料加入量为10%时,焦油产率可达到17%,同时煤气中H2,CO和CH4的含量显著增加,分别可达到44.21%,18.75%和21.97%.塑料的加入有利于提高焦油的回收率,优化热解煤气成分,对煤气的进一步综合利用具有重要意义.

| Abstract: | Recycling and harmless handling can be achieved by co-pyrolysis of coal and plastic.In this paper,we study on co-pyrolysis of different proportion of Sunjiacha coal and plastic under microwave heating conditions.The result indicates that with the increasing of proportion of plastic,char yield gradually reduced,the yields of tar markedly improved.When the proportion of plastic is 10%,the content of char yield goes up to 17%,at the same time the content of H2,CO and CH4 increased obviously in coal gas,the content of H2 is up to 44.21% and the content of CO and CH4 up to 18.75% and 21.97%.Therefore,the addition of plastic is not only benefit to improve the recovery of tar and optimize the component of pyrolysis gas,but have an great effect on the further comprehensive utilization of gas. |
