Small chlorine furnace ｜Removal of metal impurities from carbon powder by dry chlorination
Protect the base material with negative pressure operation and oxygen partial pressure control, while minimizing waste liquid with dry methods!
The "small chlorine furnace" enables the dry volatilization and removal of metal impurities such as Fe/Ni/Al remaining in carbon powder through selective chlorination using Cl2/HCl. Chlorination and volatilization are controlled with a staged temperature profile, allowing for low residue in a short time while maintaining the crystallinity and specific surface area of the base material. Additionally, by not using acidic solvents such as hydrochloric acid or sulfuric acid, the burden of waste liquid treatment is reduced, while achieving high purity of the product. 【Features】 ■ Selectively volatilizes metal chlorides through chlorination ■ Dry process eliminates the need for water washing, simplifies post-processing, and improves yield and energy efficiency ■ Base material retention design: Maintains physical properties by controlling oxygen partial pressure and residence time *For more detailed information, please download the materials or feel free to contact us.
