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, minimizing waste liquid with a dry process!
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. By controlling chlorination and volatilization with a staged temperature profile, it achieves low residue levels in a short time while maintaining the crystallinity and specific surface area of the base material. Additionally, since it does not use acidic solvents such as hydrochloric acid or sulfuric acid, it reduces the burden of waste liquid treatment while enhancing the 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 details, please download the PDF or feel free to contact us.
