Columnar Activated Carbon for PSA Nitrogen and Air Separation Systems
Coal-based columnar activated carbon candidate for buyers sourcing adsorbent media for air separation, PSA nitrogen equipment, desulfurization, solvent recovery, and wastewater polishing. Key checks should focus on CAS alignment, pellet diameter, iodine value, CTC, methylene blue value, bulk density, mechanical strength, ash/moisture limits, chloride residue, packing format, and export document readiness before RFQ confirmation.

Package and route
Packing notes
Common packing shown: 25 kg bags and 500 kg ton bags; jumbo bags and palletized options may be available
Confirm inner liner, moisture barrier, pallet dimensions, container loading quantity, and whether fumigation-free pallets are available
For cargo consolidation from China, request bag dimensions, gross weight, CBM per pallet, stacking limits, and photos of export packing
Ask whether neutral packing, buyer labels, batch labels, and COA-linked lot numbering can be provided
Applications and sourcing options
Check whether this product fits the buyer's actual application.
Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.
Use context
Common applications
Adsorbent bed media for air separation and nitrogen production equipment, subject to OEM specification approval
Airflow purification where low bed resistance and uniform pellet size are required
Industrial wastewater polishing or chemical sewage adsorption applications
Solvent vapor recovery systems requiring pellet activated carbon with controlled adsorption indices
Desulfurization, denitration, odor control, and gas-phase purification projects
Bulk industrial adsorbent procurement for consolidated export shipments from China
How we compare
Sourcing options
Factory-direct RFQ for customized iodine value and pellet size
Sample order for lab and pilot equipment validation before bulk purchase
Container-load supply in 25 kg bags or 500 kg big bags
Consolidated shipment with other non-conflicting industrial materials from China
Third-party pre-shipment inspection with sampling, photos, and document review
Private-label or neutral export packing subject to supplier confirmation
Human review
Compliance notes
Request current SDS, COA, TDS, packing list, commercial invoice, certificate of origin, and any destination-specific declarations before shipment
Confirm DG classification with the supplier and forwarder; activated carbon may require review depending on activation history, moisture content, and self-heating test status
Check whether the product is sold as activated carbon, coal-based activated carbon, or chemical auxiliary adsorbent across COA, SDS, label, invoice, and customs documents
Verify EINECS listing shown by supplier, as the extracted page lists EINECS 264-84-4 and this should be checked against the buyer's regulatory database
Confirm REACH, RoHS, food-contact, drinking-water, or NSF-related requirements only if relevant to the end use; do not assume certification from marketplace text
For air separation equipment use, confirm oxygen compatibility expectations and any equipment OEM media specification before approval
No regulatory guarantee is implied; final import, use, and customs classification should be verified by the buyer's compliance team
