Bamboo-Based Powder Activated Carbon

Bamboo-Based Powder Activated Carbon — indoor air purification, odour control and humidity buffering. Sanniu Carbon supplies this grade as a powder form, produced on our own activation lines and tested batch by batch.

Typical duty: indoor air purification, odour removal, water polishing, humidity control. Fine powder for batch dosing, decolourisation and short contact-time treatment.

The bamboo-based series is characterised by micropores of 0.4-1.2 nm, close to the size of formaldehyde molecules. Reference values for the series range from 800-1150 mg/g iodine value, 800-1200 m2/g BET surface area, 45% or higher CTC adsorption and 15% 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.

Powder carbon is dosed into the batch or the stream rather than held in a bed. Finer powder adsorbs faster but is harder to recover, so it is usually applied where contact time is short or where the carbon is consumed in the process. 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.
