Coal gasification is the process of producing syngas–a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4), and water vapour (H 2 O)–from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas". Coal gas is combustible and ...

Process. The process that creates coal varies slightly in different areas depending on the plants and conditions that are present, but the overall process is similar. There are two main phases in coal formation: peatification and coalification. Bacterial activity is the main process that creates the peat during peatification.
Coal is a hard rock which can be burned as a solid fossil is mostly carbon but also contains hydrogen, sulphur, oxygen and is a sedimentary rock formed from peat, by the pressure of rocks laid down later on top.. Peat, and therefore coal, is formed from the remains of plants which lived millions of years ago in tropical wetlands, such as those of the late .

The United States currently operates 268 coal preparation plants in 14 states according to the latest annual census of coal processing plants conducted by Coal Age . The facilities, which are primarily located in West ia (80), Kentucky (56), and Pennsylvania (44), represent a total installed feed capacity of over 200,000 tons per hour.
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production.

The discovery of gold on the Wiwatersrand was closely followed by the discovery of coal in Boksburg in 1887. The vast Witbank coalfield was developed in the 1890s and
Thermalbased power plants can produce electricity from coal or other fuel sources. The coalfired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2.
