Sustainable Ammonia Production with Low-Cost Catalysts
Publicado em 22 de março de 2024
Ammonia is one of the most extensively produced chemicals globally, finding applications across a wide array of manufacturing and service industries. The traditional production technology is the Haber-Bosch process, which mixes nitrogen gas (N2) and hydrogen gas (H2) in a reactor with a catalyst.
High temperatures and pressures are necessary for this process, which uses a lot of power. The manufacturing of ammonia is thought to be responsible for 3 % of global carbon emissions and 1–2 [...]
