Oil shale industry - Wikipedia
The oil shale industry is an industry of mining and processing of oil shale—a fine-grained sedimentary rock, containing significant amounts of kerogen (a solid mixture of organic chemical compounds), from which liquid hydrocarbons can be manufactured.
Oil shale - Wikipedia
Most exploitation of oil shale involves mining followed by shipping elsewhere, after which the shale is burned directly to generate electricity or undertakes further processing. The most common methods of mining involve open-pit mining and strip mining .
Shale oil extraction - Wikipedia
Shale oil extraction is an industrial process for unconventional oil production. This process converts kerogen in oil shale into shale oil by pyrolysis, hydrogenation, or thermal dissolution. The resultant shale oil is used as fuel oil or upgraded to meet refinery feedstock specifications by adding hydrogen and removing sulfur and nitrogen ...
Oil Shale Processing - an overview | ScienceDirect Topics
Generally, surface processing consists of three major steps: (i) oil shale mining and ore preparation (ii) pyrolysis of oil shale to produce shale oil, i.e., kerogen-derived oil, and (iii) processing the shale oil to produce refinery feedstock and high-value chemicals.
Status, disadvantages, and prospects of oil shale in China: An …
2023年12月1日 · Surface retorting technologies usually include three steps: (1) oil shale mining and ore preparation, (2) oil shale pyrolysis to produce kerogen oil, and (3) processing of kerogen oil to produce refined raw materials and high-value chemicals.
Shale Oil - an overview | ScienceDirect Topics
Shale oil is obtained by mining and processing of the shale rocks. However, extracting oil from oil shale is not as simple as extracting oil from underground oil reservoirs as shale oil naturally occurs as solid particles, which cannot be directly pumped to the surface.
Oil Shale and Tar Sands - Bureau of Land Management
The United States holds more than half the world’s oil shale, a fine-grained sedimentary rock containing organic matter from which petroleum products may be distilled. Although it has long been seen as a potential source of secure, reliable, and affordable energy, the technology to produce oil from oil shale in commercial quantities has been ...
Shale oil | Unconventional Oil, Fracking & Extraction | Britannica
One involves mining and crushing oil shale and then transporting the rock to a processing plant where it is heated in special retorts to temperatures of about 500 °C (930 °F). The intense heat releases oil vapours from the rock, which liquefy in a series of condensers.
Advances and challenges in shale oil development: A critical
2020年4月6日 · The fluid transport mechanisms through shale matrix are analyzed in terms of molecular dynamics, pore scale simulations, and experimental studies. The methods employed in fracture propagation simulation and production optimization of shale oil are also introduced.
Oil Shale - National Geographic Society
2023年10月19日 · Mining for oil shale can have damaging effects on the environment. When shale oil is combusted (heated), it releases carbon dioxide into the atmosphere. Carbon dioxide is a greenhouse gas; it absorbs and retains heat in Earth’s atmosphere, a process called the “ greenhouse effect.”
