Calcined Petroleum Coke CPC

Calcined petroleum coke is a black or dark gray hard solid petroleum product with metallic luster and porosity. It is a carbon body made of tiny graphite crystals formed into granules, columns or needles.

Petroleum coke must be calcined to meet the requirements of industrial production. The calcination temperature is usually around 1300°C. The purpose is to remove the volatiles in petroleum coke as much as possible.

Product Features

It greatly reduces the hydrogen content of calcined petroleum coke and improves the degree of graphitization. As a result, the high-temperature strength and heat resistance of the graphite electrode are improved, and the conductivity of the graphite electrode is improved.
