摘要
总结了煤热解过程中硫、氮的迁移转化规律 ,讨论了硫氮在煤气、焦油和半焦中的分配情况 ,分析了一种同时脱硫脱氮的煤解耦燃烧工艺 。
The exist forms of sulfur and nitrogen and their transformation behavior during coal pyrolysis have been briefly reviewed. The distribution of sulfur and nitrogen species among gas, liquid and solid products are also presented and evaluated simultaneously. A new coal combustion process which removing SO 2 and NO x simultaneously based on decoupling principle is also analyzed. Several research hotspot topics which are useful to decrease or control sulfur and nitrogen emissions are pointed out.
