Ammonia Cracker
PSG Engineering Company’s ammonia cracker is a system that uses heat (850–950°C) and a catalyst (nickel or ruthenium-based) to break down ammonia (NH₃) into hydrogen (H₂) and
nitrogen (N₂). The process involves vaporizing liquid ammonia, cracking it in a high-temperature reactor, and purifying the hydrogen output
PSG Engineering Company Ammonia Cracker – Working Principle and Process Information An ammonia cracker is a system that thermally decomposes anhydrous ammonia (NH₃) into a hydrogen-nitrogen gas mixture (75% H₂, 25% N₂) through catalytic cracking. Below is a step-bystep description of its operation:

Advantages of an Ammonia Cracker
- Cost-effective hydrogen source – Ammonia is cheaper and easier to handle than pure hydrogen.
- Easy storage & transport – Ammonia is simpler to store and move than compressed hydrogen.
- Stable forming gas – Produces a consistent H₂–N₂ mixture for industrial use.
- Reliable operation – Supports continuous gas production.
- Low-carbon option – Using green ammonia reduces emissions.
- Flexible integration – Works with furnaces and purification systems.
- Reduced cylinder usage – Less need for delivered hydrogen cylinders.
Applications of Ammonia Cracker Units
- Heat-Treatment Furnaces (Most Common Use) Annealing, Brazing, Sintering, bright annealing, Carburizing/neutral atmospheres Uses H₂–N₂ mixture as a reducing atmosphere.
- Metallurgical Industries metal powder reduction, stainless steel processing, Galvanizing lines, Heat-treated alloy steels Hydrogen-rich gas prevents oxidation and improves surface finish.
- Chemical & Process Industries On-site hydrogen generation for chemical reactions, hydrogenation processes Reducing agent for metal oxides, Ammonia decomposition for nitrogen supply (depending on purity needs)
- Electronics & Semiconductor Controlled atmosphere furnaces, Reduction/cleaning of components using hydrogen
- Fuel Cell Hydrogen Supply With PSA purification, cracked gas → high-purity H₂ Used for small-to-medium hydrogen fueling setups where ammonia is used as hydrogen carrier.
- Laboratories & R&D Low-cost hydrogen source Controlled H₂/N₂ mixture for experiments
- Glass & Ceramics Reduction and controlled atmosphere for specialty glass manufacturing Deoxidizing environment for ceramics processing
- Powder Metallurgy Heat treatment of sintered parts Reduction of powder oxides
