Coal is a fossil fuel composed primarily of carbons and hydrocarbons. Its ingredients help make plastics, tar and fertilizers. A coal derivative, a solidified carbon called coke, melts iron ore and reduces it to create steel. But most coal -- 92 percent of the U.S. supply -- goes into power...

Electricity can be generated using Underground Coal Gasification (UCG) syngas as feedstock by the following methods: * Combustion in a Gas Turbine Generator (GTG) * Combustion in a boiler to produce steam to drive a steam turbine The main advantage of UCG syngas as feedstock for...

Clean coal technology is an umbrella term used to describe technologies being developed that aim to reduce the environmental impact of coal energy generation. These include chemically washing minerals and impurities from the coal, gasification (see also IGCC), treating the flue gases with steam...

Linc Energy was granted an Exploration Permit for Coal at Chinchilla, Queensland - Australia in December 1998 and commenced work on site in July 1999. Gas was first produced on Boxing Day of the same year. After more than two years of producing gas, Linc was able to prove complete control of the...

Nothing about the chemistry of coal has changed since WWII, and it is still possible to synthesize fuel from coal, which ranges from about 65 percent to 95 percent pure carbon. All that’s required is hydrogen, heat, and pressure. Worldwide, such production is done only in limited amounts...

Gasoline and diesel fuel are hydrocarbons. The name gives us a clue as to how to convert coal to liquid fuel: combine hydrogen and carbon. Hydrocarbon fuels are designated by the number of carbon atoms in their molecules. For example, methane, the main constituent in natural gas, has one carbon...
