This carbonaceous product is obtained by refining oil. At Repsol we use delayed coking technology. This is a thermal cracking process which turns the heaviest fraction of oil into coke and other high value-added products.
The name of our marketed product is "Green Fuel Grade Petcoke." Only 70% of production is marketed as fuel, while the rest is used as a carbon source in the aluminum and steel industries.
