Petroleum coke's heat content in the U.S. 1960-2020
The heat content of petroleum coke used in the United States was approximately 582 trillion British thermal units in 2020. This was the lowest figure since the 1980's. The source defines heat content as the amount of heat energy available to be released by the transformation or use of a specified physical unit of an energy form (e.g. a barrel of oil). A decrease in heat content means that the fuel is used less efficiently, as more product is needed to generate the same amount of heat.
