The New Technology of Preparation Activated Carbon from Lignite

Abstract:

The lignite resource is rich in Xilingol League in Inner Mongolia. The two new methods were achieved to preparation activated carbon which used lignite as raw material. Firstly, the lignite was acidized by hydrochloric acid to prepare activated carbon. The catalytic materials in the ash as calcium, magnesium, iron and other elements were significantly reduced after that and the activated speed of the coal was significantly lower than the original coal, which are conducive to the development of uniform porous carbonized compound and decrease the hole broken. And a better surface area and adsorption properties of activated carbon was obtained. Secondly, with the carbonization and activation temperature at 800°C and 45 min, we can get the activated carbon with the excellent adsorption performance through fluidized catalysis of lignite.
