Green borsch

Bosch process, is an artificial nitrogen fixation process and is the main industrial procedure for the production of ammonia today. Green borsch World War I, the Haber process provided Germany with a source of ammonia for the production of explosives, compensating for the Allied Powers’ trade blockade on Chilean saltpeter.

During the 19th century, the demand for nitrates and ammonia for use as fertilizers and industrial feedstocks had been steadily increasing. The main source was mining niter deposits and guano from tropical islands. Haber, with his assistant Robert Le Rossignol, developed the high-pressure devices and catalysts needed to demonstrate the Haber process at laboratory scale. Ammonia was first manufactured using the Haber process on an industrial scale in 1913 in BASF’s Oppau plant in Germany, reaching 20 tonnes per day the following year. Today, the most popular catalysts are based on iron promoted with K2O, CaO, SiO2, and Al2O3. Earlier, molybdenum was also used as a promoter.

During the interwar years, alternative processes were developed, the most notably different being the Casale process, Claude process and the Mont-Cenis process by Friedrich Uhde Ingenieurbüro, founded in 1921. The steam reforming, shift conversion, carbon dioxide removal, and methanation steps each operate at pressures of about 2. The major source of hydrogen is methane from natural gas. The Haber process relies on catalysts that accelerate the scission of this triple bond. Two opposing considerations are relevant to this synthesis: the position of the equilibrium and the rate of reaction.
