Coal granular activated carbon — various mesh sizes
Water & Gas Phase

Coal Granular
Activated Carbon

Irregular granular particles from premium anthracite coal. Available in multiple mesh sizes for fixed-bed adsorption columns.

Product Overview

Coal-based granular activated carbon (GAC) is produced from high-quality anthracite and bituminous coal through steam activation. The resulting product features a well-developed pore structure with balanced micropores and mesopores, providing excellent adsorption capacity for both liquid and gas phase applications.

Available in a wide range of mesh sizes from 4×8 to 20×50, our coal GAC is the most cost-effective choice for large-scale water treatment plants, industrial filtration systems, and environmental remediation projects. Options include standard, acid-washed, and impregnated grades.

Available Mesh Sizes

4×8 Mesh

Coarse filtration, high flow rate

8×30 Mesh

Frequently Asked Questions

What is coal granular activated carbon?
Coal granular activated carbon (GAC) is produced from anthracite or bituminous coal through steam activation and crushing into irregular granular particles. It features balanced micropore and mesopore structure for versatile liquid and gas phase adsorption.
Which mesh size should I choose?
8x30 mesh is the most popular for general water treatment. 4x8 for coarse filtration with high flow rates. 12x40 for fine filtration with maximum contact area. Choose based on your flow rate and target contaminant size.
How does coal GAC compare to coconut shell GAC?
Coal GAC is 30-50% cheaper and better for large-scale industrial use. Coconut shell GAC has higher hardness, lower ash, and more micropores — preferred for drinking water and food-grade applications.
What is the MOQ and delivery time?
MOQ is 3 tons. Standard products ship within 7-10 days. Custom specifications may require 15-20 days. Free samples available for testing.
Can coal GAC be acid washed or impregnated?
Yes. Acid washing reduces ash to below 3% and neutralizes pH for food-grade applications. Impregnation with KOH, KI, or sulfur enhances removal of specific gases like H2S and mercury.
