Underground Coal Gasification | netl.doe.gov
Underground Coal Gasification (UCG) takes advantage of the same chemical reactions of coal to produce product gases, as those occurring in conventional gasifier reactors. The main difference is that in UCG the underground coal seam itself becomes the reactor, so that the gasification of the coal takes place underground instead of in a manufactured gasificationUCG-GTL - Underground Coal Gasification - Gas To Liquids,Underground Coal Gasification - Gas To Liquids (UCG-GTL) UCG-GTL is the "revolutionary" successful combination of two known processes, Underground Coal Gasification (UCG) and the conversion of the resultant Gas (Syngas) To Liquids (GTL).. UCG and GTL as separate processes have been extensively trialed and have been in commercial use in many countries for more than 50 years.UNDERGROUND COAL GASIFICATION (UCG),Underground Coal Gasification involves igniting a coal seam underground and pumping out the partially burned gases that result.
