Calcined Petroleum Coke

Calcined Petroleum Coke Image

Petroleum Coke is Calcined (roasted at high temperatures, 1200˚ to 1350˚ C) usually in gas fired rotary Kiln or coke oven or shaft kiln to remove moisture, drive off volatile matte, increase the density of the coke structure, increase physical strength, and increase the electrical conductivity of the material. The result is a hard dense, carbon (Calcined petroleum coke) with low hydrogen content and good electrical conductivity. These properties along with low metals and ash contents make calcined petroleum coke the best material currently available for making carbon anode for smelting of alumina to aluminium.
