Petroleum coke testing analyses the chemical and physical properties of pet coke to determine its quality and industrial suitability.
Pet coke testing ensures fuel efficiency, quality consistency, and compliance with environmental and industry standards.
Key parameters include, ash, sulfur content, volatile matter, fixed carbon, and calorific value.
Petroleum coke (pet coke) is primarily used as a fuel and carbon source in industries such as cement, power generation, steel, and aluminium production. It is also used in the manufacture of electrodes, anodes, and other carbon-based products.
The core difference is that GPC (Graphite Petroleum Coke) is produced by graphitizing CPC (Calcine Petroleum Coke) at temperatures exceeding (2500ºC to 3000ºC, resulting in a higher, more ordered carbon structure and lower sulfur content compared to CPC, which is calcined at lower temperatures 1200ºC to 1400ºC. While GPC is essentially “refined” CPC, both are considered essential carbon-based materials depending on the specific requirements of the foundry or smelting operation.
Petroleum coke generally has a high calorific value, typically ranging between 7,500 and 8,500 kcal/kg, depending on its grade and composition.
