摘要
采用炼钢精炼渣,通过气固碳酸化反应吸附CO2,考察了不同吸附温度下精炼渣对纯CO2和模拟高炉煤气中CO2的吸附能力。实验结果表明:吸附温度对精炼渣吸附CO2反应有显著的影响,升高温度可以提高精炼渣对CO2的吸附能力;在400℃时,精炼渣吸附纯CO2和模拟高炉煤气中CO2的量分别为4.7 mg/g和9.8 mg/g;吸附温度升高到500℃和550℃时,精炼渣对纯CO2的吸附能力强于高炉煤气中CO2;在550℃时,精炼渣吸附纯CO2和模拟高炉煤气中CO2的量达到最高,分别为14.7 mg/g和12.9 mg/g。
The steel refining slag was used for adsorption of CO2 by gas solid carbonation.The adsorption capability of the steel refining slag to pure CO2 and CO2 in the simulated blast furnace gas was investigated at different reaction temperatures.The experimental results indicated that:The adsorption temperature has a significant effect on adsorption of CO2 by steel refining slag,and the increase of temperature can improve the adsorption capability of steel refining slag;At 400℃,the adsorption amount of pure CO2 and CO2 in the simulated blast furnace gas is 4.7 mg/g and 9.8 mg/g,respectively;When the adsorption temperature is increased to 500℃and 550℃,the adsorption capability of the slag to pure CO2 is stronger than that to CO2 in blast furnace gas;At 550℃,the adsorption amount of pure CO2 and CO2 in simulated blast furnace gas reach the highest value,which is 14.7 mg/g and 12.9 mg/g,respectively.
