2015-3-12 · Calcined coke is the best material for making carbon anodes for smelting of alumina to aluminum. Petroleum coke is usually calcined in a gas-fired rotary kiln or rotary hearth at high temperatures, around 1200 to 1450 °C, to remove moisture, drive off volatile matters, increase the density of the coke, increase physical
The calcination of petroleum coke is to remove sulfur, moisture, and volatiles, and the raw petroleum coke is calcined at 1200 to 1350 ° C to make it a substantially pure carbon. The largest user of calcined petroleum coke is made of aluminum, and 70% is used to make an anode that reduces bauxite.
2019-4-30 · The amount of calcined petroleum coke is determined according to the ratio of other raw materials and carbon content. The characteristics of carburizing agent itself choose pure carbon graphitized material, reduce too much impurity in pig iron, and the selection of carburizing agent can reduce the cost of casting production.
Petroleum Coke: Industry and Environmental Issues Congressional Research Service Summary In early 2013, media outlets around Detroit, Michigan began publishing stories about large piles of petroleum coke stored along the Detroit Riverfront. Petroleum coke (petcoke) is a black-
