Ammonia synthesis typically occurs under high-temperature and high-pressure conditions, requiring specialized equipment and safety measures in an industrial environment. However, with the continuous growth in global fertilizer demand, ammonia and fertilizer plants often adopt lower reaction temperatures to cope with market competition. Common large-scale energy-saving processes in the international market include AMV, Braun, LCA, while in the Chinese market, the majority of small to medium-sized, medium-pressure ammonia production processes and various tower types are prevalent. SYAMCAT A217, SYAMCAT A126, and their pre-reduced catalysts exhibit excellent low-temperature activity in such operational environments.
