改性粉煤灰的制备及从烟气中吸收SO2试验研究
Preparation of Modified Fly Ash and Adsorption of SO2 in Flue Gas
摘要
Abstract
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 h and dried for 2 h .关键词
