Global Metallurgical Coke Market is expected to reach over USD 700.0 billion by 2020

Date: 2016-09-14

Metallurgical coke is a carbon material resulting from the manufactured purification of multifarious blends of bituminous coal. In its natural form, bituminous coal is soft; its medium-grade composite contains a high occurrence of unstable components. The majority of the unstable components are either reclaimed or recycled.

The production processes of metallurgical coke are the following:
Bituminous Coal
The bituminous coal used in the production of metallurgical coke is found in small quantities in the United States but in larger quantities in Asian and Far Eastern countries, such as India and China. Large reserves have been found in Turkey, especially on the western coastal region of the Black Sea.

Purification Process
The purification process is performed in coke batteries, which are platforms of large enclosed ovens. Once bituminous coal is loaded into the ovens (in a vacuum), it is heated to approximately 1,000 degrees Celsius for more than 22 hours. During the heating process, the unstable components are released, and the remaining solid coal endures a partial melting and subsequent resolidification to a hard carbon. The unstable components include ammonia, coal tar and dozens of other waste products.

Metallurgical Coke
The resulting solid is a stable carbon known as metallurgical coke. Due to the elimination of unstable components and volatile gasses, and also due to the partial melting, “met coke,” as it is sometimes called, has an open, porous structure and may appear glassy in some samples. Met coke has a very low waste product content; however, the “ash” elements that were part of the original bituminous coal remain trapped in the resultant coke. Met coke is available in a variety of sizes, from basketball-sized chunks to fine powder.

Metallurgical coke is used in applications requiring strong-wearing carbon of high performance, high quality and resilience. Some applications for met coke include foundry coatings, drilling applications, heat treatment, oxygen exclusion, electrolytic processes, conductive flooring, friction materials, foundry carbon raiser, corrosion materials, reducing agents, iron ore refining and ceramic packing media. Metallurgical coke is also an agent in the production of ferro-alloys, calcium carbide, elemental phosphorus and carbon electrodes.

The market capacity of global metallurgical coke was estimated to be 3.0 billion tons, and was valued at USD 673.8 billion in 2015, and is expected to reach over USD 700.0 billion by 2020, growing at a CAGR of 2.0% from 2016 to 2020.
