Abstract
The present invention relates to the use of petroleum coke for the manufacture of carbonaceous anodes for the aluminum smelting industry. The inclusion of Group 4 and/or Group 13 metal compounds as additives to the petroleum coker feedstock diminish the oxidizing tendencies of the metal impurities inherent in the petroleum coke.
