What is met coal and why is it so important to WV? WBOY 12 News

Metallurgical coal or "met" coal is a certain grade of coal that is used to produce coke, an essential ingredient in the steelmaking process, as opposed to thermal coal which is used for energy production. Met coal is rarer and more valuable than thermal coal and has fewer impurities. Although West ia is the second highest producer ...

Possible CO2 mitigation via addition of charcoal to coking coal blends ...

Processes involving biomass oxidation are considered to be CO 2 neutral since the replenishing of the biomass by normal growth will remove CO 2 from the atmosphere. Thus the use of charcoal in the production of metallurgical coke, to be used as a reducing agent in the formation of iron, would be a strategy for the reduction of CO 2 in the overall ironmaking process.

Influence of biomass on metallurgical coke quality

Influence of biomass on metallurgical coke quality

Abstract. Two industrial coal blends used in coke making were subjected to tests in order to assess the influence of waste sawdust (SC2 from chestnut and SP1 from pine) on the quality of the coke produced. The biomass was added in quantities of up to 5 wt.%. It was observed that biomass produced a substantial decrease in the plastic properties ...

More attention is paid to ironmaking as the most energy consuming segment of the process chain. For example, blast furnace ironmaking including sintering and coking plants consumes about 6575% of the entire energy at an integrated steelworks (ca. 1112 GJ/t hot metal) (Babich, 2009).Both direct and indirect coal use, in the form of coke, is presented.
