Coconut Shell Pelletised Activated Carbon

Coconut Shell Pelletised Activated Carbon — drinking water and point-of-use purification with low fines and long service life. Sanniu Carbon supplies this grade as a block and pelletised form, produced on our own activation lines and tested batch by batch.

Typical duty: drinking water, point-of-use cartridges, beverage processing, solvent recovery. Extruded or crushed block carbon with low pressure drop for deep beds and gas service.

The coconut shell series is characterised by a predominantly microporous structure matched to small molecules, with high hardness. Reference values for the series range from 900-1600 mg/g iodine value, 950-1200 m2/g BET surface area, 40% or higher CTC adsorption and 5% or lower ash, produced by physical activation. The agreed specification for your order is confirmed per batch.

Send the medium to be treated, the flow rate or concentration, the target specification and the required particle size. We confirm the grade and the agreed specification plan before quotation, and a 1-5 kg sample is available for evaluation.

Block and pelletised carbon is used where a deep bed would otherwise cause an excessive pressure drop, and in gas service where mechanical strength and low dust matter. Watch for a rising outlet concentration, a colour or odour change, or an increasing pressure drop. Any of these indicates the bed is loading up; arrange a test or a replacement before the outlet goes out of specification. Thermal regeneration and acid washing are the usual recovery routes.

Values in the specification table follow the series reference ranges and are confirmed per batch. Iodine value and methylene blue adsorption are reported in mg/g, CTC adsorption, hardness and ash content in %, bulk density in g/cm3 and particle size in mesh. Test reports name the sample tested and the method used.
