Gas Treatment
High mechanical strength and a well-developed pore structure for air purification, VOC abatement, desulfurization, deodorization and solvent recovery.
Learn MoreWhy Choose Datong Guiyi Carbon
From raw-material advantage to technical service — a quality moat that is hard to replicate.
Scarce, Superior Raw Material
We use Datong's unique low-ash, low-sulphur Jurassic coal — around 5% ash and under 0.7% sulphur, known as natural clean coal and a scarce feedstock for premium activated carbon.
Advanced Production Systems
Imported and domestic briquetting lines, energy-saving carbonization furnaces, Slep activation furnaces and refining lines deliver 12,000 tonnes of high-grade briquetted activated carbon a year.
Certified Quality
ISO 9001 certified, with products meeting GB/T, AWWA and NSF 61 standards, and a long-held share of more than 70% of China's water-plant purification carbon market.
Company Profile
Datong Guiyi Carbon Co., Ltd. is located in the Pharmaceutical Industry Park (Plot 02), Datong Economic and Technological Development Zone, Shanxi, China — a large coal deep-processing enterprise integrating activated carbon R&D, production, sales and application support. The company employs 150 people, including over 60 technical specialists, with RMB 260 million in total fixed assets and 53,200 m² of operating area, producing 12,000 tonnes of high-grade briquetted activated carbon per year.
Through independent R&D and the adoption of advanced technologies, processes and equipment from home and abroad, the company now operates two imported and two domestic briquetting lines, two high-efficiency energy-saving carbonization furnaces, two refining lines, six Slep activation furnaces, and a 600 m² laboratory and R&D centre. It has developed more than 100 stable, high-quality activated carbon grades across six major categories, trusted and favoured by customers.
Six Process Steps, Quality Controlled at Every Stage
Fully traceable from raw-material selection to packaging, ensuring stable performance and consistent batches.
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.
