Oil Shale Processing

2 Description of Oil Shale Processing. Shale oil processing is defined as an industrial process to which raw shale oil is subjected to extract oil from it—basically a process to produce unconventional oil [1].Because shale oil exists as solid sedimentary rocks, its extraction is more complex than extraction of conventional oil [1].It cannot be directly pumped out of the ground …

Oil Shale

Oil shale is different than shale oil. Shale oil (and gas) occurs in rocks where the oil is as a liquid between sediment grains. On the other hand, oil shale does not contain liquid petroleum and is actually the rock marlstone which contains kerogen, a precursor to oil. The kerogen must be heated to more than 750 degrees to convert it into a ...
