Anodes are produced by mixing the calcined petroleum coke with the coal-tar-pitch (CTP) binder, at temperatures higher than the pitch softening point, to produce the green anode paste. The paste is vibro-compacted or pressed to form the green anode block which, is finally baked to acquire the desired electrical and mechanical properties  .

A typical prebaked anode is made from a mixture of petroleum coke, coal tar pitch, and butts. An anode butt is the rest of the used anode removed from the cell during anode changing. The butts content in the new anodes can vary, but normally it is between 15% and 25%. 2. The main constituent of prebaked carbon anodes is calcined petroleum coke.
Calcined Petroleum Coke (CPC) manufacturing Process by PreRish Tri (PEPL): 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 degrees C (2192 to 2460 F).
