Determining the chemical composition and properties of shale rocks poses a significant challenge given that these materials are heterogenous and comprise a complex ...Oil shale samples were pyrolysed at different heating rates. The effect of heating rate on fractional composition of shale oil is investigated in 0.2-6 • C min −1 range. It is found that increasing the heating rate increases the content of aliphatic of the liquid shale oil. Normal paraffins of (C 10 -C 32 ) are identified in aliphatic fraction.As a versatile plant, chicory’s chemical composition and use as a suitable livestock feed supplement or as an alternative feed ingredient (AFI) are thus reviewed. Chicory is a perennial plant grown in different parts of the world, used as forage for livestock, as folklore remedies, or as a vegetable addition in human diets.Chemical composition of oil shale layers . According to the existing exploration data, the OM in the sequence of . the Attarat OS unit is represented by kerogen, usually forming 5 to 30 wt%
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 ...Shale definition, a rock of fissile or laminated structure formed by the consolidation of clay or argillaceous material. See more.…
