Effect of the additive concentration on the modification of petroleum coke and anode quality

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Calcined petroleum coke is one of the major raw materials for anode manufacturing, which is used as the carbon source in electrolytic cells for primary aluminium production. It constitutes around 65%–70% of the anode recipe. Therefore, the quality of calcined coke has an important impact on anode quality, which affects the cost, energy ...
