Decolorization Powdered Activated Carbon

Decolorization Powdered Activated Carbon

Decolorization Powdered Activated Carbon

Made from high-quality wood-based, coconut shell, or coal-based raw materials through refined carbonization and activation, this decolorization activated carbon is a black fine powder with an extremely developed pore structure that selectively adsorbs colored impurities from liquids and gases. Buyers working with sugar liquors, fruit juices, beverages, and edible oils often order it as a food grade activated carbon, so pigment removal can be completed while the valuable components of the liquid are retained.

Key Features and Specifications

A high-capacity adsorbent with a broad pore structure, developed for industrial liquid pigment removal in food, chemical, and pharmaceutical processing.

Fine black powder with a highly developed internal pore structure

High Decolorization Ability

A developed pore structure, high specific surface area, and suitable surface chemical properties deliver a strong effect on caramel color, chlorophyll, anthocyanin, azo dyes, and anthraquinone dyes.

Good Selectivity

Adsorption follows the structures, sizes, and polarities of pigment molecules, so colored impurities are targeted while effective components and nutrients are retained.

Fast Adsorption Rate

Fine particle size and uniform dispersibility allow the powder to reach adsorption equilibrium in a relatively short time under suitable contact conditions.

Iodine Value Wood-based: 700–1000 mg/g · Coconut shell: 900–1200 mg/g · Coal-based: 300–600 mg/g
Particle Size More than 80% passes through a 200-mesh sieve (particle diameter below 0.075 mm)
Specific Surface Area Mostly 800–1500 m²/g
pH Value Approximately 4 to 10
Methylene Blue Adsorption Value Coconut shell powdered activated carbon for decolorization: 180–250 mg/g
Raw Material Base Wood-based, coconut shell, or coal-based
Form Black fine powder

Applications Across Food, Pharmaceutical, and Chemical Processing

The powdered form disperses quickly in liquids, which suits batch and continuous decolorization duties across several industries.

Food Industry

Sugar and sugar liquor refining where caramel pigments and melanoidins must be removed, plus fruit juices, beverages, brewed wines, and edible oils.

Pharmaceutical Industry

Drug synthesis, extraction, and refinement steps that require colored impurities to be removed from liquid process streams.

Chemical Engineering

Purification of synthetic pigments and color control in plastics, rubber, and chemical fiber production.

Textile Printing and Dyeing

Removal of dye color from wastewater streams and support for fabric pre-treatment operations.
