Wood Based Powdered
Activated Carbon

The industry standard for decolorization. Highest methylene blue value among all PAC types.

Product Overview

Wood-based powdered activated carbon is the most widely used PAC for decolorization applications worldwide. Produced through phosphoric acid activation of sawdust, it develops an exceptionally high mesopore volume that efficiently adsorbs large color molecules, pigments, and organic impurities.

With methylene blue values reaching 280 mg/g — the highest among all activated carbon types — wood PAC is the undisputed choice for sugar refining, pharmaceutical purification, and food-grade decolorization processes.

Key Applications

  • Sugar & glucose decolorization
  • MSG & amino acid purification
  • Pharmaceutical API purification
  • Citric acid decolorization
  • Wine & spirits clarification
  • Vegetable oil refining
  • Starch syrup processing
  • Chemical intermediate purification

Frequently Asked Questions

Why is wood PAC best for decolorization?
Wood PAC has the highest methylene blue value (up to 280 mg/g) among all activated carbon types, thanks to its well-developed mesopore structure from phosphoric acid activation. Unmatched for removing large color molecules.
What industries use wood PAC?
Sugar refining, glucose production, pharmaceutical API purification, citric acid decolorization, wine and spirits clarification, vegetable oil refining, and chemical intermediate purification.
Phosphoric acid vs steam activation?
Phosphoric acid activation produces higher mesopore volume and better decolorization. Steam activation produces more micropores for general adsorption. Most wood PAC for decolorization uses phosphoric acid process.
What is the caramel decolorization rate?
Our wood PAC achieves caramel decolorization rates exceeding 100%, meeting the requirements of sugar refineries and food processing plants worldwide.
What certifications do you have?
ISO 9001, FCC food-grade, HALAL, Kosher. Every batch tested with COA. Third-party testing through SGS or BV supported.
