Calcined Coke

Calcined petroleum coke is a granule made by high-temperature roasting of a high-quality petroleum coke with a low hardness and a high porosity. The addition of calcined petroleum to chatter in the friction material not only helps prevent metal sticking and improves frictional properties. Moreover, the coke has a high porosity, increases the friction coefficient of the friction material, and reduces the thermal decay of the friction material at high temperatures.

Petroleum coke used in the production of electrodes for the steel and aluminum industries.

It has deposited on the catalysts used in oil refining, such as those in a catalytic cracker. This coke is impure and is only used for fuel. Petroleum coke's high heat and low ash make a good fuel for power generation in coal-fired boilers but is high in sulfur and low in volatile content which pose some environmental and technical problems with its combustion
