改性粉煤灰陶粒的制备及其吸附SO2性能研究
Ceramsite Sintered from Modified Fly Ash and Bentonite Clay and Its Properties of Adsorption of SO2
摘要
Abstract
Haydite is prepared from modified fly ash, bentonite clay and limestone through granulating, drying and roasting process. The characteristics of haybite are specified by scanning electron microscopy (SEM) and the measurement of specific surface area and pore size distribution. After studying the SO2 adsorption property of this ceramsite,the results show when the mass ratio of modified fly ash: bentonite: limestone: cement is 10= 1:1: 0. 4,burnt under 500 ℃ celsius for 10 min.the haydite has 3 -4 mm particle size and 32. 8 m2 · g-1 of specific surface area. The maximum S02 adsorption capacity of this haybite is 30.939.5 mg · g-1.关键词
