    The production stopped in 1963, but Wietze has hosted a Petroleum Museum since 1970. [28] Oil sands have been mined since the 18th century. [29] In Wietze in lower Saxony, natural asphalt/bitumen has been explored since the 18th century. [30] Both in Pechelbronn as in Wietze, the coal industry dominated the petroleum technologies. [31]

  3. Hydrocarbon - Wikipedia

    en.wikipedia.org/wiki/Hydrocarbon

    Petroleum (lit. ' rock oil ') and coal are generally thought to be products of decomposition of organic matter. Coal, in contrast to petroleum, is richer in carbon and poorer in hydrogen. Natural gas is the product of methanogenesis. [13] [14] A seemingly limitless variety of compounds comprise petroleum, hence the necessity of refineries.

    r-ch 2-ch 2-ch 2-r → r-ch=ch-r + ch 4 In these formulas, R represents the remainder of a cellulose or lignin molecule to which the reacting groups are attached. Dehydration and decarboxylation take place early in coalification, while demethanation begins only after the coal has already reached bituminous rank. [ 43 ]

  5. Fossil fuel - Wikipedia

    en.wikipedia.org/wiki/Fossil_fuel

    Burning coal, and to a lesser extent oil and its derivatives, contributes to atmospheric particulate matter, smog and acid rain. [39] [40] [41] Air pollution from fossil fuels in 2018 has been estimated to cost US$2.9 trillion, or 3.3% of the global gross domestic product (GDP). [9]

  6. Solid fuel - Wikipedia

    en.wikipedia.org/wiki/Solid_fuel

    It is the solid carbonaceous material derived from destructive distillation of low-ash, low-sulfur bituminous coal. Cokes made from coal are grey, hard, and porous. While coke can be formed naturally, the commonly used form is man-made. The form known as petroleum coke, or pet coke, is derived from oil refinery coker units or other cracking ...

  7. Carbon-based fuel - Wikipedia

    en.wikipedia.org/wiki/Carbon-based_fuel

    Carbon-based fuel is any fuel principally from the oxidation or burning of carbon.Carbon-based fuels are of two main kinds, biofuels and fossil fuels.Whereas biofuels are derived from recent-growth organic matter [1] and are typically harvested, as with logging of forests and cutting of corn, fossil fuels are of prehistoric origin [2] and are extracted from the ground, the principal fossil ...

  9. Cannel coal - Wikipedia

    en.wikipedia.org/wiki/Cannel_coal

    Cannel coal from the Pennsylvanian of NE Ohio. Cannel coal or candle coal is a type of bituminous coal, [1] also classified as terrestrial type oil shale. [2] [3] [4] Due to its physical morphology and low mineral content cannel coal is considered to be coal but by its texture and composition of the organic matter it is considered to be oil shale. [5]
