活性焦烟气脱硫技术研究

Research Progress on Activated Coke Flue Gas Desulfurization Technology

二氧化硫是造成我国酸雨的主要污染物质,主要来自于化石燃料的燃烧。目前烟气脱硫技术(FGD)是重要的脱硫手段,而活性焦因其高比表面积、发达的孔隙结构、丰富的官能团和高机械强度,被认为是极具前景的干法FGD技术。本文主要对活性焦烟气脱硫技术进行了介绍,以及其在国内外工业上的应用进行了综述,分析了各种技术的优缺点,并总结了存在的问题。

Sulfur dioxide（SO2）generated from the fossil fuel combustion is the chief contamination of acid rain.Flue gas desulfurization（FGD）technology was proved to be effective to remove SO2.Activated coke is one of the most commonly used dry FGD technology ascribed to its high surface area,abundant pore structure,surface functional groups,and high mechanical strength.Thus,the application,advantages,disadvantages and existing problems of activated coke technology are summarized in this paper.
