The following paper gives the reader a brief history of coal and its uses. It also analyzes the refining technique known as the Integrated Gasification Combined Cycle or IGCC as well as some history and new technologies associated with this fossil fuel.
From the Paper:"Coal is a sedimentary organic rock that contains a lot of carbon, typically between 40 and 90 percent carbon by weight. Ancient plants and animals accumulating in moist peat bogs form coal. As plants die off in a wet area, they pile up into peat. It takes between 4,000 and 100,000 years for one meter of peat to accumulate. This process happens best in river deltas or coastal plains. Over time, further deposits compress these peat seams and the carbon content of the coal is concentrated. The older the coal gets, generally, the harder and blacker it gets. There are four "ranks" of coal. Listed from lowest to highest rank, they are: lignite, subbituminous, bituminous, and anthracite. Rank is determined by energy content and chemical composition. Lignite is the youngest form of coal and is soft and brown, not much different than dried peat. Lignite has a low energy content, typically about 13 million Btu per ton. The carbon content is low also, around 40 percent. Lignite is typically used only when higher grades of coal are not available or affordable. Subbituminous coal is common in the US. It has an energy content of about 18 million Btu per ton, and is used mostly in coal-fired power plants. Bituminous coal is the most widespread form in the US and is high in energy content, averaging 24 million Btu per ton. Bituminous and subbituminous account for most coal use in America. The hardest coal, anthracite, is found mostly in Pennsylvania, but most supplies of anthracite there have been exhausted. The energy content is high, around 23 million Btu per ton, but it tends to have a high sulfur content. It is more than 90 percent carbon. "
