关于制备活性粉煤灰的研究

STUDY ON PREPARATION OF ACTIVE COAL ASH

研究了增大低炭粉煤灰的比表面积及制备活性粉煤灰的方法.用 CaCl_2溶液处理再经活化——炭化,能使粉煤灰的比表面积增大数倍;用简便方法进行特殊处理,可使比表面积增大到300 m^2/g 左右.

The methods of increasing the specific surface area of the low-carbon coal ash and preparing the active coal ash were studied.After treated by the solution of CaCl_2 and un- dergone activation-carbonization,the specific surface area of the coal ash may be in- creased several times.When the coal ash was particularly treated by a simple and conve- nient method,its specific surface area was increased to 300 m^2/g or so.
