Calcined Petroleum Coke - Oxbow

Calcined petroleum coke is a critical ingredient in the production of aluminum. It is created by placing high quality raw "green" petroleum coke into rotary kilns, where it is heated to temperatures between 1200 to 1350 ˚C (2192 to 2460 ˚F). The high temperatures remove excess moisture, extract all remaining hydrocarbons and modify the crystalline

Aluminium Bahrain creating a lasting legacy

at a temperature of 970 C. Alumina fed into these cells is liquidised by molten cryolite, which can dissolve alumina and conduct electricity at high temperatures. Partially immersed anodes, which are produced at the calciner plant, are in turn suspended above each cell and the carbon lining of the cell acts as the hode. An electrical current of

Calcined Petroleum Coke : Manufacturers, …

Calcined Petroleum Coke comes from delayed coke which extracted from oil refinery. Although Calcined Petroleum Coke contains a little bit higher level of sulfur and nitrogen than pitch coke, the price advantage still makes it widely used during steel-making and founding as a kind of carbon additive/carburant.
