Q: What is spherical activated carbon?

Spherical AC consists of uniform, round particles with >90% sphericity. This unique shape provides excellent flow characteristics, minimal channeling, and very low pressure drop in packed bed applications.

Uniform spherical particles with superior flow characteristics and minimal pressure drop for demanding gas phase applications.

Product Overview

Spherical activated carbon is produced through a specialized process that creates uniform, round particles with high sphericity (>90%). This unique shape provides excellent flow characteristics, minimal channeling, and very low pressure drop in packed bed applications.

The uniform particle size and shape make spherical carbon ideal for applications requiring consistent performance, such as gas masks, respirator cartridges, and precision filtration systems. Also used as catalyst carriers and chromatography packing material.

Frequently Asked Questions

What is spherical activated carbon?

Spherical AC consists of uniform, round particles with >90% sphericity. This unique shape provides excellent flow characteristics, minimal channeling, and very low pressure drop in packed bed applications.

What is it used for?

Gas masks, respirator cartridges, automotive cabin air filters, catalyst carriers, chromatography packing, and precision filtration systems requiring uniform flow distribution.

What sizes are available?

2×4mm for gas masks and respirators. 3×8 mesh for catalyst carriers. 4×6 mesh for industrial gas treatment. Custom sizes available on request.

How is it made?

Produced through a specialized process using coal or petroleum pitch as raw material. The spherical shape is formed during production, not by grinding — ensuring uniform density and strength throughout each particle.

What is the MOQ?

MOQ is 3 tons. Free samples available. Lead time 10-15 days for standard specifications.

Precision Engineered Carbon

Custom sphericity, size distribution, and impregnation available. Free samples for testing.
