For example, anthracite coal, which is the highest quality coal, produces more carbon dioxide per Btu than lowquality lignite. This is because anthracite lacks hydrogen, which is a small portion of the content of lower grade coals.

Lignite: This is the softest, youngest, and wettest rank of coal, often referred to as "brown coal" with a carbon content of only 2535% and correspondingly lower energy content. This is present in large amounts in some coal fields in Alaska, but is not currently targeted for mining.

This group of macerals is very sensitive to advanced coalification and the liptinite macerals begin to disappear in coals of medium volatile rank and are absent in coals of lowvolatile rank. When the liptinite macerals are present in a coal, they tend to retain their original plant form and thus they are usually "plant fossils" or phyterals.

Coal rank depends on volatile matter, fixed carbon, inherent moisture, and oxygen, although no one parameter defines rank. Typically coal rank increases as the amount of fixed carbon increases and the amount of volatile matter decreases. Anthracite coal is a highranking coal with more fixed carbon and less volatile matter than

The objective of this research was to evaluate, in salinesodic soils, the effect of the application of a low rank coal (LRC), lignite type, along with an inoculation of bacteria that release humified organic matter (HOM) from this type of coal. The soil microbial activity and related coal biosolubilization enzymes mediated by microorganisms were determined along with the chemical variables ...

Coal rank is the measure of the degree of organic metamorphism (coalification) of a coal, ranging from lowrank peat to highrank metaanthracite (Table 315) Rank can be determined through a number of chemical and physical parameters In general, no single parameter can be used throughout the entire rank range For example.
