kerogen การใช้

• This diagram is mostly used for differentiating different types of kerogen.
• The complex composition and chemistry of kerogen complicates the results.
• General composition of oil shales constitutes inorganic matrix, bitumens, and kerogen.
• They found that on average the oil is depleted to corresponding kerogen by 230.
• Type IV kerogen contains mostly decomposed organic matter in the form of polycyclic aromatic hydrocarbons.
• Kerogen can be heated, and yield up to of product per ton of rock.
• Kerogen subsequently undergoes thermal decomposition to hydrocarbons.
• Nevertheless, most research on hydrogen isotopes of kerogen show D enrichment with increasing maturity.
• The chemical process of pyrolysis can convert the kerogen in oil shale into synthetic crude oil.
• The name " kerogen " was introduced by the Scottish organic chemist Alexander Crum Brown in 1906.
• Kerogen Type III is formed from terrestrial plant matter that is lacking in lipids or waxy matter.
• The characteristics of the basement sediments can produce conditions conducive to the conversion of kerogen into petroleum.
• Pyrobitumen represents a significant fraction of the ultimate fate of petroleum liquids formed from kerogen during catagenesis.
• In 1912, he introduced the name of kerogen to cover the insoluble organic matter in oil shale.
• This process converts kerogen in oil shale into shale oil by pyrolysis, hydrogenation, or thermal dissolution.
• The kerogen in the rock can be converted into crude oil using heat and pressure to simulate natural processes.
• These processes convert the organic matter within the rock ( kerogen ) into impurities such as sulfur and nitrogen.
• Many of the coal fields date to the Carboniferous period of type III kerogen, a source of natural gas.
• The formation of polymers in this way accounts for the large molecular weights and diverse chemical compositions associated with kerogen.
• In summary, D content of kerogen and coals are complicated and hard to resolve due to the complex chemistry.
