Last updated: April 2026 dataGreen (uncalcined) petroleum coke is a carbon-rich solid by-product of crude oil refining, widely used as a fuel in cement kilns, power plants, and industrial boilers where its high calorific value offsets its elevated sulfur content. Because it has not undergone the high-temperature calcination process, it retains volatile matter and is not suitable as a direct anode material for aluminum smelting — that distinction drives the commercial separation from calcined coke. Canada is the leading US import supplier, with Germany, Brazil, and Mexico also among the top sources. Sulfur content and volatile-matter specifications are the primary quality parameters buyers negotiate.

Not-calcined (green) petroleum coke retains volatile matter and higher sulfur levels, making it suitable primarily as a fuel. Calcined coke has been heat-treated to remove volatiles and moisture, producing a dense, low-volatile carbon material used as anode stock in aluminum smelting and other electrochemical processes.
Canada is the top supplier, followed by Germany, Brazil, and Mexico, with Kuwait also among the leading sources. Supplier selection is often driven by sulfur content specifications and freight economics relative to the buyer's industrial facility.
