Product Overview
F-14 is our entry-level phosphoric acid activated wood carbon, offering an excellent balance of performance and value for decolorization applications. The phosphoric acid activation process creates a highly developed mesopore structure that excels at removing color bodies, high-molecular-weight organics, and colloidal impurities that steam-activated carbons struggle to capture.
The "F" series designation identifies our phosphoric acid wood carbon line; "14" indicates the methylene blue adsorption tier, reflecting the mesopore volume available for large-molecule adsorption.

How Phosphoric Acid Activation Works
Phosphoric acid acts as a dehydrating agent during carbonization, preventing the collapse of the wood structure and creating an extensive network of transport pores. The acid is then washed out and recovered, leaving a carbon with:
- High mesopore volume for rapid color body adsorption
- Large specific surface area for high capacity
- Fast filtering speed for efficient processing
