Activated coke
活性焦炭 / Aktivkoks / 활성 코크스
A material composed of porous carbon that has selective adsorption properties for specific substances, and has been chemically and/or physically treated (activated) to achieve high adsorption efficiency. The product is available in various forms, such as powder, granules, and cylindrical shapes.
Dry desulfurization and denitrification of combustion flue gas from power plants and steelworks (removal of sulfur oxides (SOx) and nitrogen oxides (NOx))
Manufacturing process
※This process is just one example, and the manufacturing methods vary by company.
Processing in a low-oxygen environment is required to prevent dust explosions.
The vertical roller mill VX Mill" enables grinding and particle size adjustment under an inert gas atmosphere by the following mechanical characteristics and system.
A closed-loop circulation system enables operation under an inert gas atmosphere.
Roller pressure and table speed are adjustable to achieve the target particle size.
Due to the extremely high flowability of the material, the kneading intensity must be controlled to obtain optimal formability, bulk density, and uniformity. Furthermore, wear resistance against carbon is required for all material-contact parts.
The twin-screw continuous kneader "KRC Kneader" enables adjustment of the kneading intensity while producing uniform and stable products by the following mechanical characteristics.
Kneading intensity is adjustable through paddle configuration and rotation speed.
Binder viscosity is maintained by heating the jacketed barrel.
Wetted parts are made of wear-resistant materials. And easy to replace.
