Ammonia, as one of the most highly produced inorganic chemicals, is largely used for fertilizing agricultural crops. It also serves as a building block for the synthesis of many pharmaceuticals. As regards catalyst for ammonia, or ammonia catalyst, Chempack provides ammonia synthesis catalyst and ammonia decomposition catalyst, which are specified as follows.
Ammonia Synthesis Catalyst ASC-80
The ASC-80 ammonia synthesis catalyst used for ammonia synthesis can work well at low temperature with high space velocity. The ammonia catalyst comes in the form of irregular black granules, with diameters of 1.5-3.0, 2.2-3.3, 3.3-4.7, 4.7-6.7, and 6.7-9.4mm available.

| Size (mm) | 1.5-3.0, 2.2-3.3, 3.3-4.7, 4.7-6.7, 6.7-9.4 |
| Bulk Density (kg/L) | 2.7-3.0 |
| Total Fe Content (%) | 67.5-69.5 |
| Fe2+ / Fe3+ Ratio | 0.5-0.6 |
Operation Conditions
| Temperature (°C) | 400-530 |
| Pressure (MPa) | 10-35 |
| Space Velocity (h-1) | 10,000-90,000 |
Packing: Shrink wrap the ammonia synthesis catalyst in 200L steel drums lined with plastic bags, with 3 or 4 drums per pallet.
Ammonia Decomposition Catalyst ADC-99
The ammonia decomposition catalyst ADC-99, a kind of nickel-based catalyst, is typically applied in the secondary reformer of ammonia pla
nt, which uses gaseous hydrocarbon as the raw material. The ammonia catalyst also suits hydrogen production and ammonia decomposition devices. The ammonia decomposition catalyst can be shaped like rasching rings or customized.
Application
The ammonia decomposition catalyst is commonly applicable to devices used for hydrogen production and ammonia decomposition, as well as secondary reformers in ammonia plants.

| Al2O3 (%) | 55.0 |
| CaO (%) | 10.0 |
| Fe2O3 (%) | Max. 0.35 |
| K2O+Na2O (%) | Max. 0.30 |
The ammonia decomposition catalyst provides strong heat resistance, with long-term operation under 1200℃ and no adhesion or fracture in two hours at 1300℃. The ammonia catalyst is non-melting, non-shrink, offering no deformation, excellent structure stability and high strength. The maximum percentage of the low-intensity (below 180N/particle) particles can be up to 5.0%.
Operation Conditions
| Process Conditions | Pressure (MPa) | Temperature (℃) | Ammonia Space Velocity (hr-1) |
| 0.01 -0.10 | 750-850 | 350-500 | |
| Ammonia Decomposition Rate | 99.99% (Min.) | ||
Service life: 2 years Packing: Shrink wrap the ammonia catalyst in 200L steel drums lined with plastic bags, with 3 or 4 drums per pallet.
