Hydrogen Generator

1. Principle of hydrogen generator

• Ammonia decomposition

The ammonia decomposition device uses liquid ammonia as raw material, which is evaporated and vaporized through the intermediate oil removal tank and the vaporizer. The gaseous ammonia is decomposed into 75% hydrogen and 25% nitrogen in the high-temperature catalyst bed of the decomposition furnace. The subsequent purification device removes and decomposes Trace amounts of ammonia and trace water impurities in the gas.

• Water electrolysis

The water electrolysis hydrogen production system is a water electrolysis cell composed of a pair of electrodes immersed in the electrolyte, separated by a diaphragm to prevent gas penetration. When a certain direct current is passed through, the water decomposes, and then hydrogen gas is precipitated at the cathode. Oxygen evolves from the anode. 

2. Features of Hydrogen Generator

Ammonia decomposition:

1. Low cost: Compared with water electrolysis hydrogen production, it has the advantages of less investment, small size, low energy consumption and high efficiency.

2. Reliable performance: By controlling the temperature with an automatic temperature controller and adjusting the flow rate with a valve, a continuous and stable gas volume can be obtained without the need for specially trained operators. The use of high-quality catalysts, heat-resistant stainless steel, nickel-chromium alloy electric heating elements and stainless steel valves ensures a longer service life of the entire system.

3. The equipment has a compact structure, small floor space, and is skid-mounted. The installation process is simple and requires no infrastructure. It can be placed on site and can be put into normal production after connecting the water, electricity, and air inlet and outlet pipes.

4. High safety, the decomposition pressure is as low as 0.05Mpa, it decomposes immediately after use, and the gas consumption can be fluctuated at will within the rated gas production range. Under normal circumstances, there is no need for storage tanks to store hydrogen. It is an oxygen-free hydrogen production, and the whole process of hydrogen production is uniform. It is an oxygen-free environment.

   
   

Water electrolysis:

1. No pollution, zero emissions: Using pure water as raw material, only hydrogen and oxygen are produced, zero emissions, no pollution, green and environmentally friendly.

2. Small power consumption and low cost: The unit consumption of the electrolytic cell is 4.4KW.h, greatly reducing production costs.

3. High pressure and high purity: the working pressure can reach up to 3.2Mpa, and the crude hydrogen purity is 99.7%+-2%., after purification up to 99.999%
