Petroleum coke regularly known as a pet coke is a carbonaceous strong conveyed from oil refinery.This coke can either be fuel grade or anode grade. Petcoke is more than 90 percent carbon and radiates 5 to 10 percent more carbon dioxide than coal on a for every unit-of-vitality premise when it is blazed.

As Petcoke has a higher vitality content, Petcoke transmits somewhere around 30 and 80 percent more CO2 than coal per unit of weight.The contrast in the middle of coal and coke in CO2 creation per unit vitality delivered relies on the dampness in the coal and unstable hydrocarbon in coal and coke.

Specifications and regulations Fuel grade


Parameter Unit Value Significance
Fixed carbon % (m/m) 85 - 91 High carbon indicates high calorific value.
Volatile matter % (m/m) < 12 Low VM indicates difficulty in igniting.
Gross calorific value Kcal/Kg 7,800 - 8,000 Key from customer perspective. Significantly higher than coal.

Key parameters

Parameter Unit Value Significance
Sulphur % (m/m) < 7.5 Lower is better as it is less polluting. Important from regulatory point of view.
Hardgrove Grindability Index (HGI) - 38 - 52 Low value indicates difficulty in grinding.
High carbon content --> higher calorific value
High fixed carbon content --> slower combustion
Lower volatile matter production --> difficult to ignite
Lower ash production --> less waste disposal
High sulphur content --> high corrosion and pollution
Domestic Coal
Very low carbon content --> very low calorific value
Very low fixed carbon content --> faster combustion
High volatile matter production--> easier to ignite
Very high ash production--> heat loss, disposal problem
Low sulphur content --> lower corrosion and pollution
