Kuraray Activated Carbon Alternative: Every Grade Cross-Referenced
Kuraray (marketed as KURARAY COAL™, and through its Calgon Carbon and Chemviron subsidiaries) runs one of the widest activated carbon catalogs in the world — coconut shell, coal and wood grades spanning gas-phase, water, food, gold recovery and energy storage. If you are sourcing a specific Kuraray grade and want a lower-cost drop-in with published specs and factory-direct pricing, this page maps every Kuraray grade to a HojeeCarb equivalent.
One thing up front, in the interest of an honest comparison: Kuraray's public product pages list each grade's raw material and application but do not publish quantitative specs (iodine number, CTC activity, hardness). So we cannot line grades up number-for-number from public data. What we can do is match by raw material, physical form and duty — and put our own published numbers on the table so you know exactly what you are buying. For any Kuraray grade, request their TDS/COA and compare it against the HojeeCarb figures below.
1. Kuraray at a Glance — Three Raw Materials, One Owner
Kuraray's carbon range splits across three feedstocks — coconut shell, coal and wood — in granular (GAC), powdered (PAC), pellet and fine-powder forms. Because Kuraray owns Calgon Carbon and Chemviron, several familiar coal grades (BPL, Filtrasorb, CAL, CPG, HGR, Centaur) are actually Calgon brands sold under the same group. We map by raw material and duty below, because that is the only honest basis when quantitative specs are not public.
2. Coconut Shell Grades → HojeeCarb Coconut Equivalents
Coconut shell is Kuraray's largest family — micropore-rich carbon for gas-phase, high-purity water, food decolorization and gold recovery. HojeeCarb produces coconut carbon in the same forms and duties.
| Kuraray Grade | Form / Duty | HojeeCarb Equivalent |
|---|---|---|
| GG / GS / GC | Coconut GAC & pellet — VOC, H₂S, solvent recovery, catalyst support | HojeeVapor CSP1100 (coconut pellet, CTC 40–80%) |
| GA (gold) | Coconut — gold recovery (CIL/CIC) | HojeeGold CG31 / CG32 / CG33 (6×12, iodine 1000 / 1050 / 1100) |
| GLC / GLC-P | Coconut GAC/PAC — decolorization, decaffeination | HojeePure CG1100 (food-grade coconut) |
| GW / GW-H | Coconut — drinking water, taste/odor, THM, food & beverage | HojeeAqua CG1050 + HojeePure CG1100 |
| PGW | Coconut fine granular — point-of-use filters, chlorine + VOC | HojeeAqua CG1100 (12×40 fine) |
For the full coconut range and specs, see our coconut shell activated carbon products. Gold-recovery buyers can also read the CG31/CG32/CG33 gold-carbon page for CTC/K/R figures.
3. Coal Grades → HojeeCarb Coal Equivalents (incl. Calgon Brands)
Kuraray's coal family is where the Calgon and Chemviron brands sit. These are bituminous and coal-based grades for water, PFAS, decolorization, mercury and desulfurization — the duties our coal-based activated carbon line is built for.
| Kuraray / Calgon Grade | Duty | HojeeCarb Equivalent |
|---|---|---|
| Filtrasorb™ | PFAS, water & wastewater organics | HojeeAqua BG800 (coal 8×30) — see Filtrasorb page |
| BPL™ / AP4-60 | Odor, VOC, catalyst support (coal pellet) | HojeeVapor BP60 / BP50 (coal columnar) |
| CPG™ / CAL™ / SGL | Sugar, chemical purification, decolorization | HojeeAqua BG800 / wood decolorizing PAC |
| SLA | Water organics, wastewater | HojeeAqua BG700 / BG800 |
| Centaur™ | Catalytic — chloramine / chlorine / H₂O₂ destruction | HojeeCarb catalytic coal GAC (confirm duty) |
| ST1X | Impregnated — H₂S, mercaptans, SO₂, Cl₂, HCl | HojeeVapor BG800 (4×8 H₂S) + impregnated grade |
| HGR™ | Mercury removal (impregnated) | Sulfur-impregnated mercury carbon (custom) |
| PORTLAND | Coconut & coal PAC — flue-gas dioxin | HojeeVapor BPW1000 (coal PAC injection) |

4. Wood-Based Grades → HojeeCarb Wood Equivalents
Kuraray's wood-based powders handle decolorization and purification duty in food, pharma and chemical processing. HojeeCarb's wood PAC line matches by methylene-blue decolorizing power and mesh.
| Kuraray Grade | Duty | HojeeCarb Equivalent |
|---|---|---|
| PA | Wood PAC — drinking water, humics, THM | HojeePure wood PAC |
| CPW / ENO PC / CPL / SCW | Wood PAC — decolorization, purification | HojeePure WPW1200 / WPW-MB18 |
| L2S / L3S / L4S / 3SW | Wood — decolorization, purification, catalyst support | HojeePure WPW1200 / WPW-MB18 |
CPL buyers can also see our dedicated CPL Activated Carbons alternative for food & pharma.
5. Specialty Grades — Matched on a Custom Basis
A few Kuraray grades are engineered specialty products rather than standard water or gas carbon. We are upfront that these are matched by custom spec, not pulled off the shelf:
- YP — high-purity coconut carbon for supercapacitors (EDLC) and lithium-ion batteries. An energy-storage grade with tightly controlled surface area and purity; discuss a custom coconut carbon with our technical team rather than expecting a stock swap.
- GN — carbon molecular sieve (CMS) for nitrogen separation. A structured specialty product outside the standard adsorbent range.
- GA (gas separation) — coconut grade for H₂/CO₂/He purification. Confirm target gas, purity and cycle before matching.
- T-BFU / TS / Meiping — impregnated coconut carbons for aldehyde/VOC capture and antibacterial point-of-use filters. Available as impregnated grades on confirmation of the active loading.
6. Why Buy the Alternative From HojeeCarb
- Published specs, not a black box. Where Kuraray keeps iodine/CTC/hardness off its public pages, we put our figures on the COA that ships with every batch — so you know exactly what you are loading.
- Factory-direct pricing. We manufacture coconut, coal and wood carbon ourselves, so you skip the branded markup for equivalent duty.
- Free samples before you commit. Run our grade against your current Kuraray carbon under identical conditions before allocating volume.
- Export-ready. English-speaking sales, full documentation, and shipping to 50+ countries with 5-ton MOQ on standard grades.

Frequently Asked Questions
Does Kuraray publish activated carbon specs like iodine number and CTC?
No. Kuraray's public product pages list each grade's raw material, physical form and application, but do not publish quantitative specs (iodine number, CTC activity, hardness). This is common among branded carbon makers. So a grade cannot be matched number-for-number from public data — you match by raw material, form and duty, then request Kuraray's TDS/COA and compare it against the published HojeeCarb figures before committing.
Is HojeeCarb a drop-in replacement for Kuraray / KURARAY COAL carbon?
For most water, gas-phase, decolorization and gold-recovery duties, yes — HojeeCarb offers a coconut, coal or wood grade in the same raw material and physical form as the Kuraray grade, at factory-direct pricing. A few Kuraray specialty grades (YP supercapacitor carbon, GN carbon molecular sieve, GA gas-separation grade) are engineered products we match on a custom basis rather than off-the-shelf. Always confirm with a sample and side-by-side test.
Which Kuraray grades are actually Calgon Carbon products?
Kuraray owns Calgon Carbon and Chemviron, so several 'Kuraray' coal grades are Calgon brands: BPL, Filtrasorb, CAL, CPG, HGR and Centaur. If you are sourcing one of those, our coal-based GAC (HojeeAqua BG series) covers the same duty — see our dedicated Calgon Filtrasorb alternative page for the water-treatment grades.
Can HojeeCarb match Kuraray's YP supercapacitor carbon?
YP is Kuraray's high-purity coconut shell carbon for electric double-layer capacitors (EDLC) and lithium-ion batteries — an energy-storage grade with tightly controlled surface area and purity. It is a specialty product, not a standard water or gas carbon. We can discuss a custom-engineered coconut carbon for energy storage, but confirm your surface area, purity and particle spec with our technical team first rather than treating it as an off-the-shelf swap.
What is the minimum order and do you provide samples?
MOQ is typically 5 tons for most coconut, coal and wood grades, with kilogram-scale free samples for lab testing before a bulk order. Every shipment ships with a COA covering the parameters relevant to your grade. Tell us the Kuraray grade you run and your annual volume and we'll send a matched spec sheet and FOB pricing within 24 hours.
