Calcined Petroleum Coke

Description

Calcined petroleum coke is a black or dark gray hard solid petroleum product, with metallic luster, porous, is composed of tiny graphite crystallization form granular, columnar or needle form of carbon body. The petroleum coke component is hydrocarbon, containing 90-97% carbon, hydrogen 1.5-8%, also contains nitrogen, chlorine, sulfur and heavy metal compounds.

Petroleum coke is a byproduct when raw oil of delayed coking unit is cracked at high temperature to produce light oil. The production of petroleum coke is about 25-30% of that of raw oil. Its low calorific value is about 1.5-2 times that of coal, ash content is no more than 0.5%, volatile content is about 11%, quality is close to anthracite.

Nature and Usage:

Calcined petroleum coke is mainly used to produce carbon products, such as graphite electrode, anode arc, to provide steel, non-ferrous metals, aluminium smelting; Making carbonized silicon products, such as various grinding wheels, sand, sand paper, etc.; To produce commercial calcium carbide for the production of synthetic fibers, ethyl fast and other products; It can also be used as fuel.
