煤质活性炭除灰方法比较

Comparison of methods for removing ashes from coal activate carbon

对独山子石化公司活性炭厂生产的3种煤质破碎活性炭进行了除灰实验,采用的除灰方法有化学酸洗法、重力去石法及磁分离法。从实验结果来看,每种除灰方法都有自身的优缺点,但它们之间又存在很大的互补性,如果将这几种方法联合使用,除灰效果将更加理想。

The experiments with some methods including acid washing,gravitational and magnetic separation for removing ashes from coal activate carbon producted by Active Carbon Plant in Dushanzi Petrochemical Company were carried out.The results indicated that every method had its advantages and disadvantages,but they had replenishments for each other,it was found that the results of removing ashes would be better if these methods were used together.
