| 摘 要： | 试探讨矿区电厂煤质和燃烧条件对粉煤灰物化特征(粒径分布、比表面积、孔径及孔径分布)的影响,以及粉煤灰物化特性对吸附特性和选择性的影响.研究表明:吸附容量仅与有效吸咐表面积有关;粉煤灰的粒径和孔径分布与灰熔温度ST和煤的变质程度有关;粉煤灰对活性红的吸附在试验范围内,并与langmuir模型相符合.

| Abstract: | This paper studies the effect of coal quality and combustion condition on the physicochemical features of coal fly ash in mining area power plant,which includ particle size distribution,specific surface area,pore size and distribution.The effect of the physicochemical characteristics on the adsorption characteristics and selectivity was also discussed.Researches indicate that the adsorption quantity is only related to the effective adsorption surface area.Particle size and the pore distribution of the coal fly ash depend on the fly ash smelting temperature(ST) and the coal's deterioration.The fly ash's adsorption of active red,within testing range,conforms to Langmuir Model. |

| Keywords: | coal fly ash physicochemical performance adsorption characteristics relevance study |
