活性炭负载丁二酸用于捕获烟气中的元素汞

Activated Carbon Impregnated with Succinic Acid Used for Capturing Elemental Mercury in Simulated Flue Gas

为提高活性炭(AC)对燃煤烟气中元素汞(Hg0)的捕获能力设计了一种新颖高效的AC改性方法:丁二酸(SA)浸渍法。在实验室模拟烟气条件下对处理后的活性炭(SA/AC)进行了汞捕获活性评价,并考察了温度、制备条件、空速对其活性的影响,找出了最佳的制备条件和汞捕获实验条件。结果表明SA/AC汞捕获能力远高于初始AC,110℃下5%SA/AC的活性最高。

To improve gas-phase elemental mercury（Hg0） removal efficiency of activated carbon（AC）,a novel and efficient method was proposed.AC was impregnated with succinic acid（SA / AC）.The effects of SA loading value,temperature,and space velocity on Hg0 removal efficiency of SA / AC were investigated under simulated flue gas conditions.The results showed that the Hg0 capture capability of SA / AC was much higher than virginal AC,and the maximum promotion succinic acid loading value and reaction temperature was around 5wt% and 110 ℃,respectively.
