chemical composition of coal


Types and Composition of Coal - Ground Truth Trekking- chemical composition of coal ,While "coal" is often described as a single commodity, in fact coal varies widely in important physical characteristics such as energy content (usually measured in British Thermal Units, BTU ), carbon percentage, moisture content, presence of contaminants such as sulfur, etc.OKD | Coal compositionCoal composition Coal is a mineral in which the chemical element of carbon is prevalent. Carbon content (the so-called coalification) depends foremost on the time during which the conversion from plant matter to the final mineral took place. OKD, a.s. seated ...
