Petroleum coke buyers should not request a quote by product name alone. A useful inquiry should include product direction, fixed carbon, sulfur content, ash, moisture, volatile matter, particle size, application, quantity, packing and destination. If the requirement is CPC or GPC, state the product family clearly and confirm supply by batch specifications.
Definition
Petroleum coke is a carbon material category used in industrial purchasing. CPC means Calcined Petroleum Coke. GPC means Graphitized Petroleum Coke, and semi graphitized petroleum coke and fully graphitized petroleum coke are treated as part of the GPC product family.
Product and supply reference
Petroleum Coke Specification Checklist
| Field | What buyers should provide | Why it matters |
|---|---|---|
| Product direction | Petroleum coke, CPC / Calcined Petroleum Coke or GPC / Graphitized Petroleum Coke | Sets the correct product family and specification basis |
| Fixed carbon | Target value or acceptable range | Helps match carbon level and available batches |
| Sulfur content | Maximum value or target range | Important for foundry, metallurgy and aluminum carbon material use |
| Ash, moisture, volatile matter | Test values, target ranges or control limits | Shows impurity level, drying condition and batch stability |
| Particle size | 0-1 mm, 1-5 mm or another required range | Affects screening, packing, feeding and application performance |
| Purchase terms | Quantity, packing, destination and expected delivery time | Determines quotation, logistics and supply feasibility |
Inquiry Checklist
- Product name: petroleum coke, CPC / Calcined Petroleum Coke or GPC / Graphitized Petroleum Coke
- Fixed carbon, sulfur content, ash, moisture and volatile matter requirements
- Particle size range and application
- Quantity, packing method, destination and expected delivery time
- Whether sample, test report or batch photos are required
Procurement Context
Turn this knowledge into a specification-based inquiry
For procurement, this topic should eventually be translated into product route, specification fields, quantity, packing and destination so the buyer can send an executable RFQ.
FAQ
Which petroleum coke specification should buyers check first?
Start with product direction, fixed carbon, sulfur content and particle size. Then confirm ash, moisture, volatile matter, application, quantity, packing and destination.
Are CPC and GPC both petroleum coke purchasing topics?
They can be discussed in petroleum coke purchasing, but the terms must be clear. CPC is Calcined Petroleum Coke, while GPC is Graphitized Petroleum Coke.
Can a supplier quote with only fixed carbon and sulfur content?
Those values are useful for an initial discussion, but particle size, quantity, packing, destination and application are also needed for a practical quote.
Why does the application matter?
Different applications focus on different limits for sulfur, ash, particle size and stability. Application helps the supplier match the correct product direction and batch.
Are listed specifications fixed commitments?
No. This page explains inquiry fields. Final supply should be confirmed by batch data, samples and order communication.
