difference between calcined petroleum coke and needle coke in alaska

Université du Québec à Chicoutimi

Calcined petroleum coke and coal tar pitch are the raw materials used in producing carbon anodes for aluminum electrolysis. Carbon materials derived from biomasses are low in cost and considered renewable. Partial replacement of petroleum coke with bio-coke has the potential to reduce the environmental emissions during aluminum production.
