A kind of catalyst for synthetic ammonia reaction

Abstract

The invention relates to a transition metal hydride ammonia synthesis catalyst, the catalyst comprises a transition metal hydride and a carrier, and the ammonia synthesis catalyst exhibits extremely excellent catalytic activity, especially under low temperature and low pressure conditions (1 bar, lower than 300°C) .

Description

A kind of catalyst for ammonia synthesis reaction technical field The present invention relates to catalyst technology, especially provides a kind of transition metal hydride catalyst for ammonia synthesis and Its application in ammonia synthesis reaction is especially suitable for low temperature and atmospheric pressure ammonia synthesis. Background technique [0002] Ammonia is one of the most important chemical raw materials in the world. Ammonia can be used both as a fertilizer and as a chemical important intermediate. But for now, industrial ammonia synthesis needs to be realized under high temperature and high pressure conditions, so that every year About 1% of the world's energy is used in the synthetic ammonia industry. Therefore, the development of efficient catalysts for ammonia synthesis under mild conditions is very important. Significance. Iron-based and ruthenium-based catalysts are important industrial ammonia synthesis catalysts, and iron-based ca...

However, the hydrogen poisoning effect of ruthenium-based catalysts is very obvious

[0004] To sum up, although the iron-based and ruthenium-based industrial ammonia synthesis catalysts have their own advantages and disadvantages, the two catalysts still cannot achieve high-efficiency synthesis of ammonia at atmospheric pressure and low temperature (~1bar, 150~300℃).
