# Powdered Activated Carbon (PAC) | 100–325 Mesh — YELI Carbon > Source: https://www.yelicarbon.com/product-pac.html Fine, high-surface-area powders for rapid adsorption kinetics — ideal for batch dosing, decolorization, taste & odour control and emergency treatment. [Powdered activated carbon] Product 02 ## Powdered Activated Carbon (PAC) PAC particles are ground to 100–325 mesh for maximum external surface and rapid adsorption. It is dosed directly into liquids or slurries for fast purification without fixed-bed equipment. **Definition:** powdered activated carbon (PAC) is granular carbon milled to a fine powder — typically **100–325 mesh** — so that surface area becomes the limiting factor, not particle size. Typical surface areas run **800–1,200 m²/g** (BET), and a typical PAC carries an iodine value of **800–1100 mg/g**. It is the fastest-acting format for batch dosing, decolorization and emergency treatment, with dosing usually measured in **5–50 mg/L** depending on the contaminant load.

It excels at removing colour, taste, odour, TOC and micropollutants in water, food and chemical processes. Food and pharmaceutical grades are manufactured with low insolubles, acid-washing and de-ashing options, and are available with NSF, KOSHER, HALAL and FDA-compliance documentation. - ✓Custom particle-size distribution (PSD) curves - ✓Slurry-ready and pre-wetted options - ✓Low-insoluble food and pharma grades - ✓Acid-washed / de-ashed on request ### Typical Applications - Taste & odour control in drinking water - Decolorization of sugars, syrups and oils - Pharma & fine chemical purification - COD / TOC reduction in wastewater - Soil remediation & sediment treatment - Emergency response / spill treatment ### Packaging - 15 / 25 kg bags - 500 kg jumbo bags - Big-bag with liner, custom packing Technical Data ## Typical Specifications Indicative values — final parameters are matched to your application.

Finer powder (200–325) reacts faster but is harder to filter; coarser (100–200) is easier to handle in batch dosing. Custom PSD is available. How much PAC do I need for my process? + Typical dosing is 5–50 mg/L of liquid, but the right dose depends on the contaminant and target level. Send us your liquid matrix and target, and we will recommend a dose and run a lab jar test if needed. Can you supply food-grade or acid-washed PAC? + Yes — acid-washed, de-ashed, food/pharma and slurry-ready options are all available, with a COA on every batch. How does PAC dosing differ from GAC in a gold or water plant? + PAC is dosed as a fine powder into the liquid, contacted for a short time, then removed — there is no fixed bed, so doses are easy to adjust (typically **5–50 mg/L**) but the powder is usually used once. GAC sits in a fixed or moving bed, contacts the stream continuously, and can be regenerated. In a gold plant, granular 6×12 mesh carbon with iodine **1000–1300 mg/g** is the standard for CIP/CIL circuits, with make-up around **20–100 g per tonne of ore**; PAC is rarely used there because fine powder cannot be screened, eluted and regenerated in the same way. In a water plant, PAC suits seasonal taste-and-odour events and emergency dosing, while GAC handles continuous treatment. ### Coal vs Wood vs Coconut PAC YELI Carbon supplies all three bases. Typical industry ranges: **Wood-based** PAC has the highest pore volume and methylene blue values, ideal for decolorization. **Coal-based** PAC is the workhorse for water treatment at lower cost. **Coconut shell** PAC offers low ash and high purity, preferred where consistency matters. | Property | Coal-based | Wood-based | Coconut shell | | Iodine value | 800–1000 mg/g | 700–1100 mg/g | 900–1100 mg/g | | Methylene blue | 150–200 mg/g | 200–300 mg/g | 150–250 mg/g | | Ash content | 8–15% | 3–8% | ≤ 3–5% | | pH options | Neutral–alkaline (6–11) | Acidic–neutral (4–7) | Wide (5–11), near-neutral low-ash grades | | Typical use | Municipal water, wastewater COD/TOC | Decolorization of sugars, syrups, oils | Food/pharma, taste & odour, purity-critical | | Relative cost | Lowest | Mid-range | Highest | **About YELI Carbon:** we manufacture from our own factory in Longyan, Fujian, China (20+ years, 10,000 m² plant, two activation furnaces). Hardness is tested by the ASTM D3802 ball-pan method, and every batch ships with a COA stating iodine value, hardness, moisture, ash and particle size — the test method is on the certificate. ## Need PAC for a Specific Process?
