What is calcined coke used for?

Calcined petroleum coke (CPC) is the product from calcining petroleum coke. This coke is the product of the coker unit in a crude oil refinery. The calcined petroleum coke is used to make anodes for the aluminium, steel and titanium smelting industry.

How do you make coke calcined?

Calcined petroleum coke is a critical ingredient in the production of aluminum. It is created by placing high quality raw “green” petroleum coke into rotary kilns, where it is heated to temperatures between 1200 to 1350 ˚C (2192 to 2460 ˚F).

What is coke calcination?

Coke calcination is a process that involves the heating of green petroleum coke in order to remove volatile material and purify the coke for further processing. Calcined coke is vital to the aluminum industry, where it is used to produce carbon anodes for aluminum production.

What is calcination process?

How is calcination done?

As per the popular definition, calcination is defined as the process of converting ore into an oxide by heating it strongly. The ore is heated below its melting point either in absence of air or in limited supply. This method is commonly used for converting carbonates and hydroxides to their respective oxides.
