Product Description

Huajing’s Edible Oil Decolorization Coconut Shell Carbon is a specialized adsorbent material developed through extensive research specifically for the oil refining industry. Leveraging the company's 29 years of experience in activated carbon manufacturing and its advanced biomass co-generation technology, this product is produced using high-hardness, premium-grade coconut shells as raw material. It employs a chemical-free, high-temperature steam physical activation process to precisely engineer a pore structure optimized for adsorbing pigments found in oils. It is specifically designed for the decolorization, impurity removal, degumming, and deodorization of various oils, including edible oils, mineral oils, lubricants, and biodiesel.
While ensuring high decolorization efficiency, this coconut shell activated carbon does not compromise the nutritional value or physicochemical properties of the oil itself. It facilitates rapid filtration with minimal residual oil loss, thereby significantly reducing corporate production costs and elevating the grade of finished oil products. It serves as a critical consumable for oil processing enterprises seeking both large-scale procurement solutions and stable production operations.

What are its Core Advantages?

1. Exceptional Decolorization Capability with Tangible Results:
● Iodine Value ≥ 1000 mg/g; features a highly developed microporous structure capable of efficiently adsorbing polycyclic aromatic hydrocarbons (PAHs), pigment molecules, and odor-causing substances present in oils.
● Verified through empirical testing, our Edible Oil Decolorization Coconut Shell Carbon can reduce oil color intensity by over 90%, meeting the rigorous standards required for both food-grade and industrial-grade applications.

2. High Purity and Zero Contamination:
● Ash Content ≤ 5%; heavy metal levels remain significantly below national regulatory limits, thereby preventing secondary contamination and ensuring the safety of the processed oils.
● Effectively removes surface impurities while maintaining a neutral pH range (6–9), ensuring that the chemical properties of the oil remain unaltered.

3. Cost-Effective with Significant Savings:
● High Strength (≥95%): Minimizes breakage loss and extends service life.
● Rapid Filtration Speed: Reduces equipment pressure and energy consumption, resulting in overall cost savings of over 30%.

4. Customized Services for Precise Matching:
● Supports Custom Particle Sizes: Available in ranges such as 10–24 mesh, 20–40 mesh, etc., to suit various filtration systems.
● Free Decolorization Testing: We provide complimentary testing to optimize dosage ratios and process parameters.

Production Process

Multi-Stage Activation: Carbonized coconut shells undergo a stepped-temperature activation process (850°C → 920°C → 950°C). This ensures uniform development of mesopores while preventing over-activation, which could otherwise compromise structural strength.
High-Intensity Magnetic Separation: Following activation and screening, the carbon granules pass through two stages of high-gradient magnetic separators (magnetic field strength: 12,000 Gauss) to remove trace iron particles introduced by equipment wear.
Screening and Classification: A six-layer vibrating screen system is utilized to precisely control the 20–40 mesh fraction, ensuring it constitutes ≥95% of the product. This process also screens out oversized particles (>20 mesh) and fine powders (<60 mesh), guaranteeing product uniformity.
