On ammonia synthesis shift catalysts
Thread Content
What are the common catalysts used for ammonia synthesis shift reaction, what is their efficiency, and how long is their service life?
Sulfur-resistant shift catalyst, synthesized using a full conversion process
How long is the typical usage period for catalysts?
Whether the transformation catalyst needs to be reduced, and if so, what is the reducing agent
The usage cycle depends on the composition of the medium; previously, we used it for about 5 years. I’ve also seen companies that have to replace them every year or so due to issues with the gas composition.
The relationship between shift catalysts and factors such as gas flow rates, pressure, and product quality is quite significant. The issue can be resolved by turning to specialized suppliers of catalysts or process packages, or by seeking recommendations from design firms. At present, shift catalysts are quite mature, with little difference compared to foreign products.
