| 摘 要： | 工业废气的脱硫脱硝是工厂废气排放的必要流程,而现阶段一般工厂对于烟气的处理是采用钙基化合物与SO2反应生成石膏,此法耗水量大,不能实现产物充分利用,而且不能实现同时脱硫脱硝。本文主要综述了有关脱硫脱硝的实验进展,特别是针对炭基材料在脱硫脱硝中的应用,以及金属氧化物和稀土元素作为催化剂助剂在脱硫脱硝中的作用。

| Abstract: | Removal of SOx and NOx is the necessary process before industrial distributor discharge into the air. The traditional way of flue gas treatment is through calcium compounds reactions with the SO2 and forms gypsum. This way consumes lots of water and the products can not be fully used. It＇s not to realize the simultaneous desulfurization and denitrification at the same time. This article main summarizes the research and application of the technical progress of desulfurization and denitrification, especially on the application of carbon-based materials, and the research progress of metal oxide and rare-earth elements as catalyst auxiliary. |
