Petroleum coke is a black solid coke produced by cracking and coking heavy oil (mainly residual oil) at a high temperature of 490-510℃ by a delayed coking device. "Moyuan petroleum coke is mainly sponge coke, with a production capacity of 600,000 tons/year, which is widely used in the fields of electrolytic aluminum and new energy anode materials, among others.

Calcined coke is a product made from petroleum coke as raw material by removing the humidity and volatile components of petroleum coke at a high temperature of 1300℃ in a calcining furnace and optimizing petroleum coke structure. Chambraod has a Moyuan calcined coke capacity of 200,000 tons/year. It is widely used in the fields of pre-baked anode, new energy anode, rare metal smelting, and so on.
