  2. Syngas to gasoline plus - Wikipedia

    en.wikipedia.org/wiki/Syngas_to_gasoline_plus

    The primary difference between the Fischer–Tropsch process and methanol to gasoline processes such as STG+ are the catalysts used, product types and economics. Generally, the Fischer–Tropsch process favors unselective cobalt and iron catalysts, while methanol to gasoline technologies favor molecular size- and shape-selective zeolites. [ 8 ]

  3. Synthetic oil - Wikipedia

    en.wikipedia.org/wiki/Synthetic_oil

    Synthetic oils are also used in metal stamping to provide environmental and other benefits when compared to conventional petroleum and animal-fat based products. [4] These products are also referred to as "non-oil" or "oil free". A polyalcanoate synthetic oil is widely used to lubricate pendulum clocks.

  4. Volume units used in petroleum engineering - Wikipedia

    en.wikipedia.org/wiki/Volume_units_used_in...

    Oil conversion factor from m³ to bbl (or stb) is 6.28981100 Gas conversion factor from standard m³ to scf is 35.314666721 Note that the m³ gas conversion factor takes into account a difference in the standard temperature base for measurement of gas volumes in metric and imperial units.

  5. Common ethanol fuel mixtures - Wikipedia

    en.wikipedia.org/wiki/Common_ethanol_fuel_mixtures

    Summary of the main ethanol blends used around the world in 2013. Several common ethanol fuel mixtures are in use around the world. The use of pure hydrous or anhydrous ethanol in internal combustion engines (ICEs) is only possible if the engines are designed or modified for that purpose, and used only in automobiles, light-duty trucks and motorcycles.

    So periodic oil and filter changes should still be done with synthetic oil, but some synthetic oil suppliers suggest that the intervals between oil changes can be longer, sometimes as long as 16,000–24,000 kilometres (9,900–14,900 mi) primarily due to reduced degradation by oxidation.

  7. Synthetic fuel - Wikipedia

    en.wikipedia.org/wiki/Synthetic_fuel

    After Allied bombing of Germany's synthetic-fuel production plants (especially in May to June 1944), the Geilenberg Special Staff used 350,000 mostly foreign forced-laborers to reconstruct the bombed synthetic-oil plants, [23]: 210, 224 and, in an emergency decentralization program, the Mineralölsicherungsplan (1944-1945), to build 7 ...

  8. Hydroxyl value - Wikipedia

    en.wikipedia.org/wiki/Hydroxyl_value

    The conversion between hydroxyl value and other hydroxyl content measurements is obtained by multiplying the hydroxyl value by the factor 17/560. [2] The chemical substance may be a fat, oil, natural or synthetic ester, or other polyol. [3] ASTM D 1957 [4] and ASTM E222-10 [5] describe several versions of this method of determining hydroxyl value.

  9. Syngas - Wikipedia

    en.wikipedia.org/wiki/Syngas

    Syngas, or synthesis gas, is a mixture of hydrogen and carbon monoxide, [1] in various ratios. The gas often contains some carbon dioxide and methane.It is principally used for producing ammonia or methanol.
