The Haber process, [5] also called the Haber–Bosch process, is the main industrial procedure for the production of ammonia. [ 6 ] [ 7 ] It converts atmospheric nitrogen (N 2 ) to ammonia (NH 3 ) by a reaction with hydrogen (H 2 ) using finely divided iron metal as a catalyst:

The electrochemical synthesis of ammonia involves the reductive formation of lithium nitride, which can be protonated to ammonia, given a proton source. The first use of this chemistry was reported in 1930, where lithium solutions in ethanol were used to produce ammonia at pressures of up to 1000 bar, with ethanol acting as the proton source ...
The Ostwald process begins with burning ammonia.Ammonia burns in oxygen at temperature about 900 °C (1,650 °F) and pressure up to 8 standard atmospheres (810 kPa) [4] in the presence of a catalyst such as platinum gauze, alloyed with 10% rhodium to increase its strength and nitric oxide yield, platinum metal on fused silica wool, copper or nickel to form nitric oxide (nitrogen(II) oxide) and ...
With the help of renewable electricity, water can be separated into its components, hydrogen and oxygen, as part of water electrolysis. To produce e-fuels, a synthesis gas consisting of hydrogen and carbon dioxide is provided, which is then converted into hydrocarbons in a subsequent synthesis process, which can then be used as a fuel.
Ammonia decomposition has been demonstrated to be slightly more efficient than simple hydrogen oxidation, confirming the great potential of ammonia as a fuel other than an energy carrier. [ 7 ] Unfortunately, ammonia cannot be directly synthesized on the fuel electrode of a rSOC, because the equilibrium reaction
Synthesis gas ("syngas") is obtained from biomass/coal gasification is a mixture of hydrogen and carbon monoxide. The H 2:CO ratio is adjusted using the water-gas shift reaction. Coal-based FT plants produce varying amounts of CO 2, depending upon the energy source of the gasification process. However, most coal-based plants rely on the feed ...
