Green petroleum coke (GPC) is the raw, unprocessed form of petroleum coke as it exits the coker unit in an oil refinery. The term "green" does not refer to any environmental property but is an industrial designation indicating that the material is in its as-produced, uncalcined state, still retaining residual moisture, volatile hydrocarbons, and other impurities driven off only in subsequent calcination.​
