Qizhong Chemical prepared 56 tons of 4 mm coal-based extruded activated carbon for a customer in Poland. The material was selected for a biogas purification system, where stable pellet dimensions and dependable adsorption characteristics are important for consistent operation in a fixed-bed treatment unit.
The supplied product was manufactured from high-quality anthracite coal and specified with a carbon tetrachloride activity of CTC 60%. Its low ash content and uniform 4 mm pellet form were key product characteristics for this industrial gas-treatment application.
Product Delivery Process
Based on the customer’s application and requested specification, we prepared a 56-ton batch of 4 mm coal-based activated carbon pellets. Extruded pellets provide a consistent shape that is practical for packed adsorption beds, while the anthracite-based structure makes this product suitable for demanding industrial purification duties.
The project specification focused on the product form, raw material, adsorption grade, and batch consistency. The confirmed details for this order were:
| Parameter | Specification |
|---|---|
| Product form | Extruded activated carbon |
| Pellet diameter | 4 mm |
| Raw material | High-quality anthracite coal |
| CTC activity | 60% |
| Order quantity | 56 tons |
The finished material showed the low-ash and uniform-pellet characteristics specified for the order. Uniform dimensions support consistent bed packing, while lower ash limits non-carbon mineral content in the supplied adsorbent. The bulk quantity was prepared for shipment to Poland, giving the customer a single-source supply for the planned biogas treatment project.
Activated Carbon for Biogas Purification
Biogas can contain contaminants that must be controlled before downstream use. The most appropriate carbon grade depends on the gas composition, contaminant concentration, humidity, contact time, and treatment target. For this reason, product selection should be based on the customer’s operating data rather than pellet size alone.
Qizhong supplies several grades of activated carbon for biogas treatment, including coal-based pellets and application-specific impregnated products. Where hydrogen sulfide is the primary contaminant, buyers can also review our technical introduction to activated carbon for H2S removal before confirming the final grade.
Client Focus
For this order, the central product requirements were a 4 mm pellet size, CTC 60 adsorption grade, low ash content, and uniform material. Qizhong matched these stated priorities with an anthracite-based extruded activated carbon intended for industrial gas purification.
