Standardized, Precise and Traceable
Every batch passes six strictly controlled process steps, safeguarding adsorption performance, mechanical strength and batch consistency.
Raw Material Selection
Clean, environmentally sound raw materials — selected Datong Jurassic low-ash, low-sulphur coal for uniform porosity, high purity and consistent quality.
Selected Jurassic coalBriquetting
Raw coal is pressed into uniform granules or briquettes on imported and domestic briquetting lines, ensuring a consistent product form.
Briquetting linesCarbonization
Sealed high-temperature treatment in energy-efficient carbonization furnaces forms the initial carbon skeleton and removes volatiles.
Sealed, high temperatureActivation
Steam activation in Slep furnaces creates a rich, multi-stage pore structure and maximises specific surface area.
Slep activation furnacePrecision Screening
Graded screening ensures the particle size distribution meets specification, with stable flow rates and consistent filtration.
Controllable particle sizeLaboratory Testing
Iodine value, methylene blue value, hardness, ash, moisture and pH are tested in line with international industry standards.
