| 摘 要： | 将活性焦担载氧化铁制得Fe/AC脱硫剂用于烟气脱硫,在最经济的烟气脱硫温度窗口(120℃～250℃)显示出高的脱硫活性.考察操作条件对其脱硫活性的影响,并借助EXAFS和TPD表征技术对其内在原因进行探讨.Fe/AC脱硫剂在排烟温度下用于脱硫,其活性明显优于活性焦和纯Fe2O3,且载体炭无氧化烧损.Fe/AC吸硫后形成2种含硫物质:H2SO4和Fe2(SO4)3,H2O和O2的存在可增加Fe/AC对SO2的吸附硫容.由高比表面活性焦制得的Fe/AC有更高的脱硫活性,这源于活性组分Fe2O3在其上良好的分散性.Fe/AC用于脱硫应在适宜空速(800L/(kg·h)]下操作. |

| Abstract: | Activated coke was used to support Fe2O3(Fe/AC) for flue gas SO2 removal. Reaction conditions on DeSOx activity were investigated. The results show that Fe/AC had higher activity than AC or Fe2O3 at temperature of 120 degrees C-250 degrees C. H2SO4 and Fe2(SO4)3 were formed after Fe/AC sorbed SO2, H2O and O2 increased the amount of SO2 adsorption. Fe/AC derived from AC of higher BET surface area had higher DeSOx activity. Fe/AC was suitable to be used at GHSV below 800 L/(kg.h). |
| Keywords: | Fe/AC desulphurizer flue gas SO2 removal EXAFS TPD |
