subbituminous coal typically contains 35 45 carbon

Sub-bituminous coal Wikipedia

Sub-bituminous coal is a type of lower grade coal which contains 35%-45% carbon. The properties of this type are between those of lignite, the lowest grade coal, and those of bituminous coal, the second highest grade of coal. Sub-bituminous coal is primarily used as a fuel for steam-electric power generation.
