Hydrogen and nitrogen are used to produce ammonia; how much iron catalyst is needed to produce one ton of ammonia?

Producing one ton of ammonia generally does not require a specific amount of iron catalyst, as the iron catalyst is not consumed in the reaction and primarily serves to accelerate it. The amount of iron catalyst used depends on the reactor design and operating conditions, rather than being directly related to the amount of ammonia produced. .

Thank you. {:1_90:} If we temporarily ignore the reactor design and consider reaction conditions of 500°C and 20 MPa, how much iron catalyst would be required? What is the price of iron catalysts commonly used in ammonia synthesis?

Under reaction conditions of 500°C and 20 MPa, the amount of iron catalyst used is typically determined based on the size and design of the reactor. Generally, in industrial production, the amount of catalyst to be used can be estimated based on the volume of the reactor, but the exact value requires calculation using the detailed specifications of the equipment. As for price, the market price of iron-based catalysts varies due to factors such as raw material costs, manufacturing processes, and supply and demand dynamics. It is recommended to contact specific chemical suppliers or conduct market research to obtain the most accurate current price information. .

You’re welcome. If you have any other questions, feel free to ask at any time! Wish you a great day! .

I assume your question is about the catalyst loading amount in the ammonia synthesis tower. In other words: how much iron-based catalyst is required per ton of synthetic ammonia produced. Ammonia synthesis towers using nitrogen and hydrogen are classified as axial or radial based on the flow direction of the feed gas in the bed, and as low-pressure or high-pressure towers based on the operating pressure. During project design, depending on the chosen structural format, operating pressure, and space velocity, the amount of catalyst required to produce one ton of synthetic ammonia varies. Generally speaking, based on the ammonia synthesis capacity, the range for the amount of traditional iron-based catalysts required is: a catalyst production intensity of 20–80 t NH3/m^3 cat.d. This range is a bit broad; it needs to be accurately defined in conjunction with design parameters such as the flow pattern in the reactor, pressure, and space velocity. If it is not the precise design phase and only rough estimates are needed, it is sufficient to calculate the budget using a conservative value of 20–30 t NH3/m^3 cat.d.
