Anodes - Aluminium Bahrain

Carbon anodes are produced from the following ingredients: calcined petroleum coke and coal tar pitch. The coke is first crushed and segregated into size fractions then mixed to obtain the required anode quality. This dry mix is preheated then mixed with pitch to bind the coke particles into anode blocks. Appliions:

Petroleum Coke (Petcoke) - GNGROUPMS | PETROLEUM OIL

The further processing of green coke by calcining in a rotary kiln removes residual volatile hydrocarbons from the coke. The calcined petroleum coke can be further processed in an anode baking oven in order to produce anode coke of the desired shape and physical properties. The anodes are mainly used in the aluminum and steel industry.

Petroleum coke – DYM Resources

Petroleum coke Residual crude oil left over from oil refining can be further processed to produce petroleum coke (also called petcoke) in delayed coking units. Petcoke is a versatile, cost-effective source of energy and high-quality carbon.

Aluminium smelting - Wikipedia

For manufacturing of the graphitized anodes, anthracite and petroleum coke are calcined and classified. They are then mixed with coal-tar pitch and pressed. The pressed green anode is then baked at 1200 °C and graphitized. Coke anodes are made of calcined petroleum coke, recycled anode butts, and coal-tar pitch (binder).

Calcined Petroleum Coke Assessment Explained | S&P Global

We began assessing anode-grade calcined petroleum coke (CPC) on a monthly basis in May 2013 at the request of the aluminum industry. The US Gulf CPC price assessment was the first to reflect the spot tradable value for CPC used by aluminum smelters, in a market where most purchases are done quarterly or semi-annually, and often retroactively.
