Upgrading of raw anthracites by acid extraction and chemical activation |
| 초록 |
The upgrading of raw anthracites was carried out by extraction with hydrochloric acid and chemical activation with potassium hydroxide. Prior to the chemical activation, the raw anthracites were ball milled for size reduction and treated with hydrochloric acid solutions to extract ash components and to increase their carbon content. The data obtained by elemental analyses show that ash components such as silica and alumina were effectively extracted during acid treatment, which depends on the concentration of hydrochloric acid. Furthermore it was shown that the chemical activation combined with acid extraction can be a promising process for preparing moderate-quality activated carbon using raw anthracites. |
