Using A Lime Kiln For Calcining Petroleum Coke Rotary

Production and Application of Calcined Coke In Rotary ...

2015-3-12  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 strength, and electrical conductivity of the material.
