What are the types of coal USGS

What are the types of coal? There are four major types (or “ranks”) of coal. Rank refers to steps in a slow, natural process called “coalification,” during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are: Anthracite: The highest rank of coal.

Coal Analysis and Production Information Thermo Fisher

Coal Analysis and Production Information Thermo Fisher

Coal is a common energy source in the steel industry to extract iron from iron ore, and in the cement production process. The four main types of coal are lignite, sub-bituminous, bituminous, and anthracite. Each type has varying amounts of hydrogen, oxygen, nitrogen, sulphur, and carbon, and as a result they have different uses.

Emissions from the Cement Industry

Emissions from the Cement Industry

May 09, 2012 Cement manufacturing is highly energy- and emissions-intensive because of the extreme heat required to produce it. Producing a ton of cement requires 4.7 million BTU of energy, equivalent to about 400 pounds of coal, and generates nearly a ton of CO 2. Given its high emissions and critical importance to society, cement is an obvious place to ...
