  • Underground Coal Gasification netl.doe.gov

    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 gasification vessel at the surface. 1 Obviously, this has the one great cost-saving and simplifying advantage of not requiring the coal to be mined in order to be gasified.

    13/02/2021· The industries, such as underground coal mining industry that use steel structures in underground environments, where A. ferrooxidans is present, therefore, need to be aware of the impacts of such a bacterium on the integrity of the steel structure. 4. Conclusions. An experimental program was conducted to study the influence of A. ferrooxidans in corrosion of cable bolts commonly used in

  • Underground Coal Gasification: A Brief Review of

    01/06/2009· Coal gasification is a promising option for the future use of coal. Similarly to gasification in industrial reactors, underground coal gasification (UCG) produces syngas, which can be used for power generation or for the production of liquid hydrocarbon fuels and other valuable chemical products. As compared with conventional mining and surface gasification, UCG promises lower capital

  • South Africa: The future of underground coal gasification

    25/09/2018· In broad terms UCG is a technology where coal is ignited underground with a controlled flow of oxidant gas, (such as air, enriched air etc.) and water. It converts the coal into synthetic gas, of which the gas is directly used as fuel, co-fired with other fuels such as natural gas, or coal and can power gas turbines for electricity generation. To clarify whether UCG constitutes a mining

    A. Taskaev, in Underground Coal Gasification and Combustion, 2018. Abstract. Underground coal gasification technology, conceived in 1868, has not attained a fully commercial status after almost 150 years of its development. It is important to spell out specific criteria that must be met before UCG may be considered for a large commercial application, especially given complex nature of UCG
