“oil shale”的概念、定义、翻译、参考文献-科学参考

oil shale

Chemistry

A fine-grained carbonaceous sedimentary rock from which oil can be extracted. The rock contains organic matter – kerogen – which decomposes to yield oil when heated. Deposits of oil shale occur on every continent, the largest known reserves occurring in Colorado, Utah, and Wyoming in the USA. Commercial production of oil from oil shale is generally considered to be uneconomic unless the price of petroleum rises above the recovery costs for oil from oil shale. However, threats of declining conventional oil resources have resulted in considerable interest and developments in recovery techniques.

Chemical Engineering

An oil-bearing fine-grained carbonaceous sedimentary rock containing an organic matter called kerogen. It is generally uneconomic to extract oil from oil shale unless the cost of extraction falls below the cost of petroleum. A number of recovery methods, such as fracking, are currently being pioneered in response to threats of declining oil reserves.

Geology and Earth Sciences

Dark grey or black shale containing organic substances that yield liquid hydrocarbons on distillation, but that do not contain free petroleum.
