Hydrogen Maker Ammonia Cracker System , Liquid Ammonia Generator

Hydrogen is indispensable for the bright hardening of metals. But, viewed from the standpoint of safety,

hydrogen gas is by no means an advantageous atmosphere. Dissociated ammonia atmosphere or

forming gas is the only furnace atmosphere that can make up the demerits of hydrogen and function

nearly 100% as if it were hydrogen gas. There are cases where forming gas cannot replace pure

hydrogen, but such cases are very rare. For almost all applications involved, forming gas atmosphere

will answer the purpose.

An ammonia cracker, NH3-Cracker or hydrogen generator is used for the production of forming gas. Hydrogen

and Nitrogen are

generated in a cost effective way in a volume ratio of 3 : 1 or in a weight ratio of 14 : 3. Capacities from

5m3/h to 60m3/h are available.

The NH3 is coming from bottles or from an ammonia tank. The ammonia gas is preheated in a heat

exchanger and vaporizer and then cracked in the main furnace unit. The furnace is electrically

heated by special LGO heating elements.

The dissociation of ammonia gas NH3 takes place at a temperature of 920°C in the presence of a

special nickel catalyst in an electrically heated furnace.
2NH3-N2 + 3 H2
The cracked gas then passes the heat exchanger for cooling and for preheating the incoming gas.

This way and in combination with the low power consuming LGO heating

elements, it can be made sure that only a minimum of electricity has to be used for the cracking process.

Technical figures;

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).
