Coal Process Coking

Coking Process an overview ScienceDirect Topics

It is well established that the coking process and thermoplasticity, can be markedly modified by the addition of organic and inorganic materials to coals. This chapter discusses a study to elaborate the influences of adding various organic compounds, and organic materials, on the thermoplastic properties of a noncaking bituminous coal over a range of pressure and at two heating rates.

Metallurgical coal Wikipedia

Metallurgical coal or coking coal is a grade of coal that can be used to produce good-quality coke. Coke is an essential fuel and reactant in the blast furnace process for primary steelmaking. The demand for metallurgical coal is highly coupled to the demand for steel. Primary steelmaking companies often have a division that produces coal for coking, to ensure a stable and low-cost supply. Metallurgical coal is low in ash, moisture, sulfur and phosphorus content, and its rank is usually bituminous

What is Coking Coal Aspire Mining Limited

The Chinese coking coal market is likely to be the largest consumer for Ovoot coking coal due to its size and proximity. Premium coking coals such as Fat (Ovoot coal) and Primary coals, are in particular high demand within China primarily due to the low ratio of these coals in China’s own coal reserves but also due to the growing requirement for higher quality coking coals in the coke industry.

Coking coals. Although chemical composition alone cannot be used to predict whether a coal is suitable for coking, prime coking coals generally have volatile matter contents of 20 to 32 percent—i.e., the low- and medium-volatile bituminous ranks.

This is why we start by converting our coal into metallurgical coke.
