Oil shale in Estonia - Wikipedia

Oil shale (Estonian: põlevkivi) is a strategic energy resource that constitutes about 4% of Estonia's gross domestic product. The oil shale industry in Estonia is one of the most developed in the world. In 2012, the country's oil shale industry employed 6,500 people – about 1% of the national workforce. Of all the oil shale fired power stations in the world, the two largest are in Estonia. In 2012, 70% of mined oil shale was used for electricity generation, accounting for about 85% of Estonia's total electricity production. A small

Shale oil extraction - Wikipedia

Internal combustion technologies burn materials (typically char and oil shale gas) within a vertical shaft retort to supply heat for pyrolysis. Typically raw oil shale particles between 12 millimetres (0.5 in) and 75 millimetres (3.0 in) in size are fed into the top of the retort and are heated by the rising hot gases, which pass through the descending oil shale, thereby causing decomposition of the kerogen at about 500 °C (932 °F) . Shale oil mist, evolved gases and cooled combustion gases are removed from the top of the r

oil shale | National Geographic Society

Mar 04, 2013 · Oil shale is a type of sedimentary rock that is rich in kerogen. Kerogen is a part of rock that breaks down and releases hydrocarbons when heated. Hydrocarbons are substances made entirely of hydrogen and carbon. Petroleum and natural gas are probably the most familiar hydrocarbons. The hydrocarbons in oil shale can be used as an alternative to petroleum or natural gas.
