摘　　要：介绍了活性焦联合脱硫脱硝技术的机理、工艺和优点。指出了活性炭脱硫脱硝工艺具有可以实现同时脱除SO_2,NO_x和粉尘,脱除效率高,投资小等优点,通过加热再生活性焦,可获得高浓度的SO_2气体,用于生产硫酸、液体二氧化硫或硫磺,有效回收硫资源。该技术具有流程简单、占地面积小、无二次污染、费用低、应用范围广等特点,比较适合我国国情。The mechanism, techniques and advantages of activated coke combined desulfuration and denitration technology is described. It is pointed out that the technology has a lot of virtues such as removing NOx, SO2 and particulate at the same time, high efficiency, and low investment, etc. high concentration of SO2 which can be used in the production of sulfuric acid, liquid sulfur dioxide or sulfur can be obtained by regenerating the used activated coke through heat process. The technology has advantages of simple process flow, compact installation, no secondary pollution, low cost and wide range of application, etc. , which is suitable to the situations in China.
