is a mixture of organic chemical compounds that make up a portion of the organic matter in sedimentary rocks.
Tar are usually mixture of clayand sand combined with water and varying amounts of a blackthick tar called bitumen. Oil shale is a rock that contains a waxy mixture of hydrocarbons called kerogen.
Perhaps your question should be rephrased as: Is oil shale better than crude oil. My simple answer is: Not necessarily. The oil shale is correctly termed kerogen or "unmatured oil" that has been trapped in shales. Extracting and burning oil shales (rock + kerogen) is a low grade fuel (see related link) so I would not consider this better than a good grade crude (Sweet Texas crude). The transformation of the kerogen to a synthetic oil, which frequently is not better than common grades of sweet crude. For example, if there is high sulfur content, then market price may be lower than Texas sweet crude. Also, a complicating factor for refineries is the arsenic content, which comes from the retorting process, and would reduce the market price of the synethetic oil. As discussed in the related link, some of the lower gravity synthetic oil may be used to produce jet fuel or kerosene. The general rule that no two oil reservoirs produce the same crude, applies to synthetic oil from oil shale, but it is more complex as it depends on the kerogen present in the formaion and manner in which the kerogen is transformed into synthetic oil. Please read the related link.
The rock in question is oil shale, from which aspirin, nylon, and perfume can be obtained as by-products through a process called retorting. Oil shale is heated to release kerogen, a precursor to oil, which can then be further processed to produce various products including aspirin, nylon, and perfume.
Chlorophyll contains the metal magnesium.
The nucleus of the cell contains the genome.
Oil shale is a type of rock that contains kerogen, a precursor to oil. When heated, the kerogen in oil shale can be converted into oil and gas. This process is known as pyrolysis.

tMax is the temperature at which maximum hydrocarbons are emitted during the S2 phase of pyrolysis. During the S2 phase, only kerogen is emitted as all other hydrocarbons should have been released during the S1 phase. A higher tMax indicates that the kerogen required higher pyrolysis temperatures to crack. A lower tMax indicates that the kerogen requires lower pyrolysis temperatures to crack. Kerogen cracked at lower temperatures (lower tMax) is more immature since it did not encounter equal temperatures/pressures in situ. Kerogen cracked at higher temperatures is said to be more mature, since all easily accessible kerogen was already cracked in situ (indicating a prolonged exposure to heat and pressure).
Fossil + pressure equals kerogen Kerogen + pressure equals bitumen Bitumen + pressure equal petroleum Petroleum + pressure equals gasoline
two earths, further, coal+pressure=uncut diamond, and cut that using tool then pressure + fosil = kerogen then pressure + kerogen = bitumen then pressure + bitumen = petroleum then pressure + petroleum = gasoline
Coal, natural gas, nuclear power, kerogen
Oil shale is a type of rock that contains a substance called kerogen, which can be converted into oil through a heating process called retorting. It is a potential unconventional source of oil, but extracting oil from oil shale can be expensive and environmentally challenging due to the energy-intensive process and potential environmental impacts.
They allow for the sticking together of kerogen particles in the petroleum process, and create links with the atom cores.
The mining of oil shale requires the extraction of kerogen, a solid organic material, from underground deposits. This involves surface mining or in-situ extraction methods that can be energy-intensive and cause environmental impacts such as land disturbance, water use, and production of greenhouse gases. The extracted kerogen must then undergo a retorting process to produce shale oil.
