  2. Propane - Wikipedia

    en.wikipedia.org/wiki/Propane

    Propane was first synthesized by the French chemist Marcellin Berthelot in 1857 during his researches on hydrogenation. Berthelot made propane by heating propylene dibromide (C 3 H 6 Br 2) with potassium iodide and water. [9] [10]: p. 9, §1.1 [11] Propane was found dissolved in Pennsylvanian light crude oil by Edmund Ronalds in 1864.

    en.wikipedia.org/wiki/Endothermic_gas

    Synthesised in the catalytic retort(s) of endothermic generators, the gas in the endothermic atmosphere is combined with an additive gas including natural gas, propane (C 3 H 8) or air and is then used to improve the surface chemistry work positioned in the furnace.

    Per tonne of ethylene, 1–1.6 tonne of carbon dioxide (depending on the feedstock) is being produced. [4] Resulting in a staggering amount of more than 300 million tonnes of carbon dioxide that is annually emitted into the atmosphere of which 70–90% is directly attributed to the combustion of fossil fuel.

    Produced in early days of coal gasification; however, only became common after invention of Otto cycle internal combustion engine for which it was an ideal fuel, as well as small-sized, reliable gas producers, which allowed the easy generation of producer gas nearly anywhere a supply of anthracite or coke was available. Gas generally not ...

  6. Atmospheric chemistry - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_chemistry

    Atmospheric chemistry is a branch of atmospheric science that studies the chemistry of the Earth's atmosphere and that of other planets. This multidisciplinary approach of research draws on environmental chemistry, physics, meteorology, computer modeling, oceanography, geology and volcanology, climatology and other disciplines to understand both natural and human-induced changes in atmospheric ...

    en.wikipedia.org/wiki/Gas

    Drifting smoke particles indicate the movement of the surrounding gas.. Gas is one of the four fundamental states of matter.The others are solid, liquid, and plasma. [1] A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).

  9. Atmospheric carbon cycle - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_carbon_cycle

    Methane (CH 4) is one of the more potent greenhouse gases and is mainly produced by the digestion or decay of biological organisms. It is considered the second most important greenhouse gas, [10] yet the methane cycle in the atmosphere is currently only poorly understood. [11] The amount of methane produced and absorbed yearly varies widely. [10]
