INTRODUCTION Calcined petroleum coke (CPC) has been used for more than 120 years to produce the carbon anodes used in the Hall-He´roult aluminum electrolysis process.

Grupo Unimetal - About Coke

About Coke. The green petroleum coke, one of the products generated in the oil coking process, was, until 1934, considered only as a waste and discarded in the environment. Since then, for being a rich source of carbon and energy factor and for containing low ash, it has become an essential product for many industries.
