ABSTRACT:
A method of reducing the airburning tendency of petroleum coke and carbon anodes made therefrom includes calcining the coke and spray quenching the calcined coke with an additive-containing water. The additive includes an effective amount of a compound of aluminum which is soluble in the quench water. The additive is deposited on the quenched coke product surface and protects the coke from oxidation or premature combustion when in contact with the atmosphere at high temperatures. The additive-coated coke can then be formed into an anode which also has a reduced tendency to airburn during use in a high temperature environment such as an aluminum reduction cell or an electric furnace operation.
