ABSTRACT:
High quality petroleum sponge coke suitable for use in the manufacture of electrodes is produced by adding an effective amount of an oxygen-containing carbonaceous material which tends to decompose at high temperatures, such as sawdust, coal, or lignite to delayed coker fresh and/or recycle feed. This addition eliminates or reduces the formation of shot coke and promotes the formation of high-quality, easy-to-grind petroleum sponge coke.
