In this study, an alternative approach based on microwave-enhanced ammonia synthesis for Haber-Bosch process was carried out under moderate pressure of 0.1–0.65 MPa and temperature range of 280–400 °C over a stable CsRu/CeO₂ catalyst. The ammonia production rate is significantly improved under microwave conditions. At 0.65 MPa and 320 °C, maximum ammonia production rate was achieved at H₂/N₂ ratio of 1/1. Stable performance was obtained in a 6-cycles of startup-shutdown operation for cumulative on-line time of 80 h. The work demonstrates the potential of microwave catalytic technology for the distributed ammonia synthesis using renewable power having intermittent nature of energy supply.

在这项研究中，在 0.1-0.65 MPa 的中等压力和 280-400 °C 的温度范围内，在稳定的 CsRu/CeO ₂催化剂上进行了一种基于微波增强氨合成的替代方法，用于 Haber-Bosch 工艺。微波条件下氨产率显着提高。在 0.65 MPa 和 320 °C 下，在 H ₂ /N ₂比率为 1/1时实现了最大的氨生产速率。在 6 个周期的启动-关闭操作中获得了稳定的性能，累积在线时间为 80 小时。该工作证明了微波催化技术在使用具有间歇性能源供应性质的可再生能源进行分布式氨合成方面的潜力。
