In North Dakota, the Great Plains Synfuels Plant converts coal into synthetic natural gas (syngas). Syngas produced from coal can also be used to produce electricity and hydrogen. Currently, no commercially operating facilities in the United States produce liquids from coal, but coal has been converted to liquids in South Africa for decades.
Classification of coal based on volatile matter and cooking power of clean material Sponsored Links Coal is a readily combustible rock containing more than 50 percent by weight of carbonaceous material formed from compaction and indurations of variously altered plant remains similar to those in peat.
Coal—A Complex Natural Resource. An overview of of factors affecting coal quality and use in the United States . By Stanley P. Schweinfurth. INTRODUCTION. Coal is abundant in the U.S., is relatively inexpensive, and is an excellent source of energy and byproduct raw materials.
The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or "ranks," of coal are determined by carbon content. There are four ...
Classifications of Coal. There are four basic types of coal. Classifications, or coal ranks, are based on how much carbon, volatile matter, and heating value are contained in the coal: Anthracite (hard coal) is the highest-ranked coal. It is hard and jet-black, with a moisture content of less than 15%.
