  2. Ammonia - Wikipedia

    en.wikipedia.org/wiki/Ammonia

    In the bloodstream, glutamine is a source of ammonia. [164] Ethanolamine, required for cell membranes, is the substrate for ethanolamine ammonia-lyase, which produces ammonia: [165] H 2 NCH 2 CH 2 OH → NH 3 + CH 3 CHO. Ammonia is both a metabolic waste and a metabolic input throughout the biosphere. It is an important source of nitrogen for ...

  3. Ammonia production - Wikipedia

    en.wikipedia.org/wiki/Ammonia_production

    Alternatively, ammonia from wastewater can be sent into an ammonia electrolyzer (ammonia electrolysis) operating with renewable energy sources to produce hydrogen and clean water. [22] Ammonia electrolysis may require much less thermodynamic energy than water electrolysis (only 0.06 V in alkaline media). [23]

  4. Ammonia pollution - Wikipedia

    en.wikipedia.org/wiki/Ammonia_pollution

    Ammonia seeps into aquatic ecosystem in many different ways from both anthropogenic (waste water, fertilizers, and industrial waste) and natural (Nitrogen fixation and air deposition) sources. [20] Ammonia is toxic to most aquatic life including fish, corals, and planktonic crustaceans. [21] Ammonia can have 2 different forms in water.

  5. Haber process - Wikipedia

    en.wikipedia.org/wiki/Haber_process

    The main source was mining niter deposits and guano from tropical islands. [7] At the beginning of the 20th century these reserves were thought insufficient to satisfy future demands, [8] and research into new potential sources of ammonia increased.

  6. Nitrogen fixation - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_fixation

    The dominant industrial method for producing ammonia is the Haber process also known as the Haber-Bosch process. [70] Fertilizer production is now the largest source of human-produced fixed nitrogen in the terrestrial ecosystem. Ammonia is a required precursor to fertilizers, explosives, and other products. The Haber process requires high ...

  7. Syngas - Wikipedia

    en.wikipedia.org/wiki/Syngas

    Chemical uses include the production of methanol which is a precursor to acetic acid and many acetates; liquid fuels and lubricants via the Fischer–Tropsch process and previously the Mobil methanol to gasoline process; ammonia via the Haber process, which converts atmospheric nitrogen (N 2) into ammonia which is used as a fertilizer; and oxo ...

  8. Nitrification - Wikipedia

    en.wikipedia.org/wiki/Nitrification

    Nitrogen cycle. Nitrification is the biological oxidation of ammonia to nitrate via the intermediary nitrite.Nitrification is an important step in the nitrogen cycle in soil.The process of complete nitrification may occur through separate organisms [1] or entirely within one organism, as in comammox bacteria.

  9. History of the Haber process - Wikipedia

    en.wikipedia.org/wiki/History_of_the_Haber_process

    The history of the Haber process begins with the invention of the Haber process at the dawn of the twentieth century. The process allows the economical fixation of atmospheric dinitrogen in the form of ammonia, which in turn allows for the industrial synthesis of various explosives and nitrogen fertilizers, and is probably the most important industrial process developed during the twentieth ...
