Ammonia Conversion To Hydrogen
The method of making hydrogen from ammonia
There are techniques today, to understand the way of converting ammonia into hydrogen. Ammonia is a compound containing nitrogen and hydrogen. Its conversion to hydrogen is of great significance in today's world, related to the change of energy.
The method of making hydrogen from ammonia is the first reason. In ammonia molecules ($NH_3 $), hydrogen atoms can be separated. After a specific reaction, hydrogen can be separated from ammonia. Common methods include pyrolysis. In the high temperature environment, ammonia molecules are energized and cracked, nitrogen is aggregated into nitrogen molecules ($N_2 $), and hydrogen escapes. The reaction formula is roughly: $2NH_3\ stackrel {high temperature} {\ longrightarrow} N_2 + 3H_2 $.
However, the pyrolysis method requires huge energy, so it is supplemented by catalysis. Choosing an appropriate catalyst can lower the energy threshold of the reaction and promote the decomposition of ammonia. Excellent catalysts can efficiently convert ammonia into hydrogen at milder temperatures and pressures. For example, catalysts made of certain metal oxides or alloys can accelerate the bond cracking of ammonia molecules during the reaction, making the precipitation of hydrogen smoother.
There are electrochemical methods. Ammonia is used as the electrolyte, and an electric current is passed to initiate a reaction at the electrode. Ammonia loses electrons at the anode, nitrogen leaves in a gaseous state, and hydrogen is precipitated by electrons at the cathode. This electrochemical method has strong controllability and can be linked to electrical energy, making it unique in specific situations.
Ammonia hydrogen production method, no matter what method, is committed to high efficiency, energy saving and environmental protection. Hope that in the future, this method can be perfected, adding bricks and tiles to the rise of hydrogen energy, making the road to energy more prosperous.
