Typical sourcing range
Specifications buyers can use to prepare an RFQ
These are common or configurable manufacturing ranges, not a batch guarantee. Final acceptance values, methods and tolerances are confirmed in the signed product specification and batch COA.
| Raw material | Primarily wood based and commonly phosphoric-acid activated; selected economic grades may be coal based |
|---|---|
| Form | Powdered activated carbon |
| Particle size | Common 200 or 325 mesh grades, normally specified with a minimum passing rate |
| Methylene blue | Common target range: 150-200 mg/g |
| Iodine value | Typical supporting range: 800-1,050 mg/g |
| Ash | Common target range: <=5-10% |
| Moisture | Typically <=5% |
| pH | Unneutralized phosphoric grades may be 2-5; washed or neutralized grades are commonly 4-7 |
| Bulk or tapped density | Typical reference range: 250-450 g/L; method must be stated |
| Application-specific fields | Caramel decolorization, molasses value, iron, chloride, phosphate and filtration time |

Application fit
Common use directions
- Sugar and starch-sugar liquids
- Citric acid and fine chemicals
- Edible-oil and gelatin processing
- Food, beverage and process-liquid decolorization
Custom manufacturing
Fields that can be reviewed
Raw material, activation route, particle size, methylene blue, caramel decolorization, pH, iron, phosphate, chloride and filtration time.
Test-method note: Food-contact or drinking-water suitability is grade-specific and must be supported by the applicable current documents. No blanket compliance claim is made for every grade.

How to specify Decolorization PAC for a bulk order
Use the application, equipment and agreed test methods to turn a typical product range into a contract specification.
Selection factors
- Test the carbon against the actual process liquid because color bodies, impurities and competing solutes vary by feedstock.
- Define initial and target color, dosage, contact time, temperature, pH and the downstream filtration process.
- Use methylene blue, caramel decolorization, filtration time, iron and ash where they reflect the purchasing objective.
- Confirm destination-specific food, beverage or process documents for the exact grade before making a suitability claim.
Quality checks to discuss
- Minimum passing rate at the contracted mesh
- Methylene-blue or caramel-decolorization test
- pH with the preparation method stated
- Iron, ash and filtration time when required
- Actual-liquid sample comparison before a bulk order
Contract boundary: The signed specification identifies guaranteed values, methods, sampling and tolerances. Website ranges remain sourcing references.

FAQ
Decolorization PAC purchasing questions
Methylene blue, caramel or molasses decolorization, iron, ash, pH, filtration time and testing against the buyer's actual liquid are usually more informative.
Yes. Washing and neutralization can be reviewed, but the pH test method, carbon-to-water ratio and contact time must be stated in the specification.
Documents are reviewed for the specific grade and destination regulation. Suitability is not assumed from the product name alone.
