Exploration on Methods of Making PAFC Using Coal Gangue

Abstract:

Article Preview

The paper expounded the impact of coal gangues on environment. Also it deals with the feasibility of making polymeric aluminum and ferric chloride (PAFC) using coal gangue. Through orthogonal test, the paper explores such factors as roasting temperature, roasting time, hydrochloric acid concentration, reaction temperature and grain size influence on the making process, and give the best operation conditions: roasting temperature is 700°C, roasting time is 1.5~3.5h, hydrochloric acid concentration is 25%~30%, reaction temperature is 120°C and grain size is 60 mesh. At last, the qualities of products are analyzed and the conclusion is given: it is feasible to make PAFC from coal gangue and it should be popularized.
