LPF Phosphoric Acid Wood Powder Carbon – High-efficiency Decolorization for Food & Pharma

LPF series is a high-performance wood-based powdered activated carbon prepared by phosphoric acid chemical activation process. Using high-quality wood chips as raw material, it forms a well-developed mesoporous structure with excellent decolorization and impurity removal capacity, mainly used for decolorization and purification of liquid products in food, pharmaceutical and chemical industries.

Key Features

  • High Decolorization Efficiency

    Developed mesoporous structure with excellent macromolecular pigment adsorption, methylene blue value ranges from 225 to 240 mg/g for different grades.

  • Fast Adsorption Kinetics

    90% of particles pass 200 mesh, fully contacts with feed liquid, short decolorization cycle and high production efficiency.

  • Stable Phosphoric Acid Process

    Controllable pore size distribution with good decolorization selectivity, low adsorption of effective product components.

  • Grade Optional

    Available in LPF-F14 and LPF-F16 grades, which can be selected according to decolorization depth requirements.

Applications

  • Wine & Beverage Decolorization: Wine, beverages and brewing products require color, odor and impurity removal to improve taste and clarity. LPF's phosphoric acid-activated mesoporous structure adsorbs macromolecular pigments and colloidal impurities without stripping desirable flavor compounds.

  • Sugar Liquor Refining: Sugar production demands removal of colored impurities to improve whiteness and product quality. LPF's developed mesopores target sugar color molecules effectively, providing consistent decolorization performance.

  • Pharmaceutical & Chemical Purification: Chemical products and pharmaceutical intermediates need decolorization and refining to improve purity. LPF's fast adsorption kinetics and high decolorization efficiency support continuous industrial production.

  • Food Additive Refining: Food additives and fermentation products require color and odor control to meet food safety standards. LPF's stable quality and reliable safety certification support these applications.

Technical Advantages

Technical Advantages.png
  • Phosphoric acid activation creates rich mesopores with better macromolecular pigment decolorization effect than coal-based powdered carbon.

  • Stable batch quality and consistent performance suitable for continuous industrial production lines.

FAQ

Q: What is the difference between LPF-F14 and LPF-F16?

A: LPF-F14 has methylene blue value ≥225 mg/g, suitable for conventional decolorization. LPF-F16 has methylene blue value ≥240 mg/g with stronger decolorization capacity for deep decolorization of high-color-value feed liquids. For the strongest decolorization, consider F-18.

Q: What is the recommended dosage?

A: Typical dosage ranges from 0.1% to 0.5% of feed liquid weight, varying with raw material color value and target chroma. Jar testing is recommended. For higher dosage efficiency, F-16 or F-18 may achieve better results at equivalent dosage.

Q: Can LPF be used for drinking water treatment?

A: LPF series is mainly designed for liquid product decolorization in food and pharmaceutical production. For municipal drinking water treatment, we recommend coal-based B-series powdered activated carbon.
