DESCRIPTION
Explore description details to support your evaluation.
Coconut shell activated carbon is a hard, low-dust adsorbent made by carbonising coconut shell and activating it with steam. Its dense, microporous structure gives a high surface area and strong uptake of small molecules, which suits drinking water treatment, process liquid polishing, food and beverage contact work, and vapour-phase odour control. The feedstock contains little ash, so the carbon stays clean and consistent.
Powder, Granular and Columnar Forms
The same coconut shell carbon can be supplied in three forms, and the choice usually follows the separation duty. Powder is dosed into liquid and removed by filtration, giving fast adsorption for batch or shock dosing. Granular carbon works in fixed beds, allowing low pressure drop, backwashing and reuse. Columnar carbon is extruded into cylinders for packed beds and gas-phase service, offering low dust and good mechanical strength.
Selecting the Right Form
Start with the fluid, the target compound and the contact time available. Powder suits short-cycle liquid polishing; granular suits continuous columns and larger volumes; columnar suits air, solvent vapour and odour duties. Then match the particle range and bed design, as capacity, moisture, ash and pH affect performance.
Working with the Specification
Values shown on this page describe the coconut shell series and are a starting point, not a batch guarantee. Delivered figures depend on the raw shell, the activation run and the cut selected. Confirm the key parameters against your process conditions and ask for the applicable batch data with the quotation.
To narrow the choice, send your treatment target, flow rate or concentration, required particle cut and planned quantity. We can then discuss the form and grade that fit the duty and reply with a quotation for your enquiry.

ADVANTAGES
Explore advantages details to support your evaluation.
Three coconut shell carbon forms, one material base, chosen by how each duty handles flow, contact time and regeneration.
Powder form for short-contact liquid duties
Milled coconut shell carbon gives fast adsorption kinetics in batch and continuous liquid treatment where contact time is limited and fine dispersion matters more than bed strength.
Fast kinetics
Granular form for fixed-bed service
Granular coconut shell carbon balances hardness, bulk density and hydraulic flow, so it suits pressure and gravity beds that must hold shape through repeated backwashing.
Bed stability
Columnar form for low pressure drop
Extruded columnar carbon offers an ordered bed with low pressure drop and low dust, useful for vapour-phase and compact gas purification duties.
Low pressure drop
One coconut shell base across all three forms
Because powder, granular and columnar grades start from the same coconut shell series, a plant can compare forms on one specification set before choosing a cut.

OUR COMMITMENTS
Six Reasons Industrial Buyers Trust Sanniu Carbon
The steps our team follows once your inquiry arrives, and what is confirmed in writing before any order.
We review your duty first
We check the medium being treated, the target result and the product form you need, then discuss a selection direction instead of quoting immediately.
Scope of the cited specifications
Quoted figures refer to the frozen specification set for this page and are confirmed per batch before quotation, so the scope of each reference is stated up front.
Batch documents confirmed before trade
The applicable batch values and the documents we can provide are agreed before the order, and no series-wide claim is extended to a single delivery.
Packing agreed when the order is confirmed
Packaging format and moisture-protection requirements are checked at order confirmation, and the order information confirmed by both sides governs.
Price, quantity and lead time by manual check
Availability, price and delivery date are verified by our team and take effect only through a written quotation or an order confirmed by both sides.
Post-delivery follow-up on agreed channels
Questions about use or documents after delivery are received and followed up through the contact channel agreed with you.

Common questions on choosing a form, reading the specification plan and confirming an order for coconut shell activated carbon.
Which coconut shell activated carbon form should I choose?
Match the form to the duty. Powdered carbon gives fast adsorption in batch or short-contact liquid duty. Granular carbon suits fixed beds with lower pressure drop and longer service life. Columnar carbon is a hard, low-dust extruded form for vapour and gas duty and for deep beds where mechanical strength matters. Tell us the medium, flow or concentration, and the target specification, and we can confirm the form.
What are the typical specifications for this series?
Indicative series values are iodine value 900-1600 mg/g, methylene blue adsorption 135-210 mg/g, BET surface area 950-1200 m²/g, CTC adsorption 40-99%, ash content 1-5%, moisture 3-10%, pH 6.5-8.5, and particle size 4-40 mesh for the granular cut. The granular form also shows a hardness of at least 95% and a bulk density of 0.45-0.55 g/cm³. Batch values are confirmed before quotation.
How is particle size agreed for powder, granular and columnar forms?
The ordered cut is agreed per application. The series range is 4-40 mesh, and the final cut depends on whether you run a fixed bed, a slurry, or a gas stream, and on the pressure drop your system allows. The cut is stated in the agreed specification plan and checked on the batch sample before shipment.
Can you supply a sample for evaluation?
Sample supply is one of the points we confirm with you rather than a fixed published term. Send the intended medium, target specification and the form you want to test, and we will share the sample arrangement and the associated documents for your evaluation. No performance guarantee is implied by a sample.
What is the ordering and order confirmation process?
After your inquiry, we check the use scenario, treatment target and product form, and discuss the selection direction. We state the applicable scope of the referenced specifications and documents; batch values and available documents are confirmed before the transaction. Packaging and moisture protection are checked at order confirmation, and price, available quantity and lead time are verified by our team in a written quotation or order.
Which documents apply to this coconut shell series?
We can share the specification plan for the selected grade and the documents that apply to it. Third-party reports are issued for the tested sample only and are not a certification of the whole series. Tell us the destination market and the document you need, and we will confirm what is available before the order.
