It was actually first discovered by Karl Frederic Kuhlmann of Lille, who obtained a patent sixty years earlier.
This procedure replaced the inefficient Birkeland-Eyde method, which involved air passing through a special zone generated by an electric arc. Its formulator worked with assistant Eberhard Brauer and Friedrich Uhde, who later developed the dual-pressure method for this, which involves cooling in a heat exchanger train resulting in preheating tail gas. It was actually first discovered by Karl Frederic Kuhlmann of Lille, who obtained a patent sixty years earlier. But its namesake developed a more efficient catalyst; the catalyst used today is most often a platinum-rhodium metal gauze heated to about 900 degrees Celsius. This method was greatly improved by the introduction of the work of Haber and Bosch, since it requires the combustion of ammonia followed by absorption in water. FTP, name this premiere way to make nitric acid.
