Product Overview
F-18 is the flagship of our phosphoric acid wood carbon series, delivering maximum mesopore development and decolorization capacity. With methylene blue adsorption exceeding 240 mg/g, this grade handles the most challenging color loads while maintaining the rapid filtration and consistent performance that production managers depend on.
The premium performance of F-18 comes from extended phosphoric acid contact time and optimized activation temperature profiles that maximize pore development without compromising particle integrity. The result is a carbon that processes more color per pound, reducing overall carbon consumption and waste generation.

Key Application Areas
- High-color-load sugar syrups — cane sugar with high polyphenol content
- Dark beer and spirits — achieving target color without over-filtration
- Recycled oil re-refining — removing oxidation products and pigments
- Specialty chemical production — high-purity intermediates
- Water-based ink and coating purification
Economic Analysis
While F-18 carries a higher per-pound price than F-14 or F-16, the superior capacity often delivers lower total treatment costs:
- 15–20% lower carbon dosage for equivalent decolorization
- Reduced filter cake volume and disposal costs
- Faster cycle times = higher production throughput
- Less frequent filter media replacement
