380V 460V 415V High Purity Hydrogen Ammonia Cracker Unit for Cooper Tube
Ammonia Cracker for hydrogen generation takes liquid ammonia as the source. Having being vaporized,
the ammonia then is heated and decomposes into the mixed gas with 25% nitrogen and 75% hydrogen
under the action of catalyst. In theory, one Kg of ammonia can produce 2.64 Nm3 mixed gas.
Our equipment possesses the characteristics and advantages of compact structure, low space
requirement, small investment, simple operation, low energy consumption and long service life.
Supported by and combined with the XRFC series purifying equipment of our company, the higher purity
shielding gas can be obtained. However, the ammonia as source must be of first class or above, to be
exact, the purity of the source ammonia must be no less than 99.8%.
Properties and Characteristics:
The gas made in this method is a good protective gas which can be used widely in semiconductor
industry, metallurgical industry and other industries and science research which need protective gas.
1. Ammonia is easy to decompose: With not very high pressure, under catalysts, and
a temperature controlled at 750~800ºC, the ammonia will nearly completely decompose, with the
decomposing rate reaching 99.9%.
2. Easy to refine the gas: As the raw material, the liquid ammonia is of very high purity. The volatile
impurities are only little inert gas and water dissolved in the liquid ammonia and there is nearly no
oxygen. Meanwhile, under such conditions, the ammonia decomposition is irreversible. So the water
can be removed by adsorbing with a dew point of -60 ºC while the gas doing through the 5A molecular
sieve. By this way, the nonmetallic elements, for example, chlorine and oxygen which are unpopular
in semiconductor industry can be removed.
3. In China, the liquid ammonia as raw material is accessible at a low price and the raw material
consumption is also relatively smaller( In theory, each Kg of ammonia can create 2.64 Nm3 mixed gas).
