Product Description
75% H₂ + 25% N₂ Ammonia Decomposition for Hydrogen Production
This SMT reflow soldering ammonia decomposition hydrogen production equipment is a specialized gas production system customized for the electronic welding industry. It integrates ammonia cracking, gas purification, and stable gas supply into an efficient and energy-saving SMT protective atmosphere hydrogen production solution.
Working Principle
The vaporizer operates at 80Kg/hr capacity, utilizing electric heating to vaporize water which then heats liquid ammonia. The system employs solid-state relay heating for reliable power output, ensuring consistent vaporization while saving energy. Vaporization temperature is maintained at 35-40°C to ensure ammonia enters the decomposition furnace in gaseous form, preventing liquid ammonia from causing nickel catalyst poisoning.

- Heating Chamber: Utilizes low watt density pure alloy heating wires with hot-swappable installation, allowing replacement without stopping airflow for continuous operation.
- Catalyst: High-temperature nickel catalyst from Southwest Chemical Research Institute with long service life, high decomposition efficiency, and ideal decomposition gas xenon index.
- Thermal Insulation: Composed of lightweight aluminum silicate fiber formed by vacuum suction filtration, providing excellent heat insulation and high thermal efficiency to reduce operating costs.
- Pressure Reducing Valve: FTSHER from the United States ensures stable and safe physical operation.
- Temperature Control: Features two digital display controllers with adjustable K-type thermocouples using advanced microcomputer design and domestic brand pneumatic components.
- Alarm Function: Audible and visual alarm systems for safety monitoring.
This equipment is widely compatible with various SMT lead-free reflow soldering processes and serves as core supporting equipment for precision PCB soldering production. The system relies on mature ammonia decomposition catalytic cracking technology using industrial liquid ammonia as raw material to generate a stable hydrogen nitrogen mixture of 75% hydrogen and 25% nitrogen, perfectly matching the reducing protective atmosphere required for reflow soldering.
The entire equipment features high-quality nickel-based catalysts with high decomposition efficiency and stable reaction. Coupled with high-precision purification devices, it effectively removes water vapor and impurities to produce high-purity protective gas, eliminating PCB pad oxidation, virtual soldering, color differences, and significantly improving welding yield.
As a professional hydrogen and nitrogen generator for reflow soldering, this system adopts an integrated structure with compact layout and small footprint. The fully automatic intelligent control system enables continuous 24-hour operation without frequent manual intervention. Equipment features easy start-stop operation, constant gas supply pressure, and fully controllable gas purity, perfectly adapting to uninterrupted production line requirements.
Compared to traditional bottled mixed gas, on-site gas production through ammonia decomposition significantly reduces gas consumption costs while eliminating safety hazards associated with gas cylinder transportation and storage.

Technology Overview
Ammonia decomposition hydrogen production uses liquid ammonia as raw material, decomposing it into hydrogen and nitrogen through catalyst action. The resulting hydrogen-nitrogen mixture contains 75% hydrogen and 25% nitrogen, which can be used directly as a reducing protective gas or further purified to obtain high-purity hydrogen.
Ammonia serves as an excellent hydrogen storage carrier with a mass hydrogen storage density of 17.6-17.8wt% and volume hydrogen storage density 1.7 times that of liquid hydrogen. Compared to liquid hydrogen's -253°C storage requirements, liquid ammonia liquefies at only -33°C under standard atmospheric pressure, offering milder storage conditions and lower costs.
Core Components
Ammonia Decomposition Furnace: Furnace core structure typically uses heat-resistant stainless steel (2520/Cr25Ni20) with U-shaped tube vertical or plum blossom shaped column designs for uniform airflow distribution and extended service life.
Heating System: Nickel chromium alloy heating elements in external or internal heating configurations, with internal heating saving approximately 25% electricity consumption. Some systems support rapid heating wire replacement in 10-30 minutes without stopping production.
Insulation & Temperature Control: Reinforced aluminum silicate fiber insulation controls furnace wall temperature rise within 40°C. Digital temperature control combined with PLC intelligent systems provide stable temperature maintenance with alarm functions.
Catalyst Technology: Nickel-based catalysts traditionally required 800-850°C for stable conversion. Recent advancements include Fuzhou University's low-temperature catalyst operating below 500°C with 99.5% conversion rate, and Dalian Institute of Chemical Physics' catalyst achieving 99.3% conversion at 400-450°C with 800+ hours stability.
Purification System: Temperature swing adsorption (TSA) technology using dual tower zeolite molecular sieve adsorption removes residual ammonia and moisture, reducing dew point to -70°C with residual ammonia ≤10ppm and oxygen content below 3ppm. Deoxygenation devices can further purify to obtain 99.99%+ hydrogen purity.
Industry Development Trends
With global hydrogen energy industry development, ammonia decomposition hydrogen production is experiencing rapid growth due to convenient storage and controllable costs. Key development directions include high-performance low-temperature catalysts, equipment miniaturization and modularization for distributed applications, and integration with green ammonia industry for zero-carbon supply chain solutions.
