  2. Factorio - Wikipedia

    en.wikipedia.org/wiki/Factorio

    Factorio is a construction and management simulation game developed and published by Czech studio Wube Software. The game was announced via an Indiegogo crowdfunding campaign in 2013 and released for Windows , macOS , and Linux on 14 August 2020 following an early access phase, which was made available on 25 February 2016.

  3. Sicilian method - Wikipedia

    en.wikipedia.org/wiki/Sicilian_method

    In its most basic form the ores were piled in a mound and ignited. The semi-pure sulfur flowed down and the solidified mass was collected at a lower level. It was the only industrial method of recovering sulfur from elemental deposits until replaced by the Frasch process. [1] Most of the world's sulfur was obtained this way until the late 19th ...

  4. Contact process - Wikipedia

    en.wikipedia.org/wiki/Contact_process

    The contact process is a method of producing sulfuric acid in the high concentrations needed for industrial processes. Platinum was originally used as the catalyst for this reaction; however, because it is susceptible to reacting with arsenic impurities in the sulfur feedstock, vanadium(V) oxide (V 2 O 5) has since been preferred.

  5. Coal liquefaction - Wikipedia

    en.wikipedia.org/wiki/Coal_liquefaction

    The resulting coal tars and oils from pyrolysis generally require further treatment before they can be usable as motor fuels; they are processed by hydrotreating to remove sulfur and nitrogen species, after which they are finally processed into liquid fuels. [11] In summary, the economic viability of this technology is questionable. [10]

  6. Oleum - Wikipedia

    en.wikipedia.org/wiki/Oleum

    Oleum (Latin oleum, meaning oil), or fuming sulfuric acid, is a term referring to solutions of various compositions of sulfur trioxide in sulfuric acid, or sometimes more specifically to disulfuric acid (also known as pyrosulfuric acid). [1] Oleums can be described by the formula ySO 3 ·H 2 O where y is the

  7. Polysulfide - Wikipedia

    en.wikipedia.org/wiki/Polysulfide

    The energy released in the reaction of sodium and elemental sulfur is the basis of battery technology. The sodium–sulfur battery and the lithium–sulfur battery require high temperatures to maintain liquid polysulfide and Na + -conductive membranes that are unreactive toward sodium, sulfur, and sodium sulfide.

  8. Pyrotechnic composition - Wikipedia

    en.wikipedia.org/wiki/Pyrotechnic_composition

    Zinc – used in some smoke compositions, together with sulfur used in some early amateur rocket fuels, also in pyrotechnic stars; heavy, zinc-based compositions may require additional lift to fly high enough; moisture-sensitive; can spontaneously ignite; rarely used as primary fuel except in smoke compositions, can be encountered as a ...

  9. Sulfation - Wikipedia

    en.wikipedia.org/wiki/Sulfation

    Sulfation is a process used to remove "sulfur" from the combustion of fossil fuels. The goal is to minimize the pollution by the combusted gases. Combustion of sulfur-containing fuels releases sulfur dioxide , which, in the atmosphere, oxidizes to the equivalent of sulfuric acid , which is corrosive.
