摘要
研究了对粉煤灰进行改性并用以从烟气中吸收SO_2,考察了温度、m(Ca(OH)_2)/m(Na_2SiO_3·9H_2O)、液固体积质量比对粉煤灰改性的影响。结果表明:在m(Ca(OH)_2)/m(Na_2SiO_3·9H_2O)=2/1、温度80℃条件下,对粉煤灰改性14h,干燥2h,所得改性粉煤灰对烟气中SO_2的吸收量达137.998mg/g,吸收效果较好。
The preparation of modified fly ash and adsorption of SO2 in flue gas were studied.The effects of temperature,m（Ca（OH）2）/m（Na2SiO3·9H2O）and mass ratio of liquid-to-solid on modified fly ash were examined.The results show that the adsorption effective of modified fly ash for SO2 in flue gas is good,the adsorption reaches 137.998 mg/g under the conditions of temperature of 80 ℃,m（Ca（OH）2）/m（Na2SiO3·9H2O）=2/1,coal fly ash being modified for 14 hand dried for 2 h.
