A fourth coal type classification is directed towards coals of lignite rank which are sometimes referred to as ‘brown’ coal At very low ranks, coal types manifest themselves as color variations, ranging from dark brown to a ‘pale’ brown hue (George, 1982) ()In part, these color variations are the result of the ratio of preserved plant material to resinous componentsAnthracite is the highest metamorphic grade and most desirable coal since it provides the highest energy output With even more heat and pressure driving out all the volatiles and leaving pure carbon, anthracite can become graphite Anthracite coal, the highest grade of coal Humans have used coal for at least 6,000 years, mainly as a fuel source16 Energy and Mineral Resources – An Introduction to Geology2023年11月1日 Anthracite Coal – High Carbon Content and Heating Value Anthracite coal is a type of coal that stands out for its high carbon content and impressive heating value With carbon content ranging from 86% to 97%, it contains the highest percentage of carbon among all coal ranksThis high carbon content contributes to its exceptional heating value, making anthracite Types of Coal Anthracite, Bituminous, Subbituminous, LigniteThere 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 carbonrich, and harder material The four ranks are: Anthracite: The highest rank of coal It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high What are the types of coal?
