Abstract

Ammonia is crucial as it serves as a key nitrogen source in fertilizer production to enhance crop growth and as an emerging energy carrier due to its high hydrogen content and ease of liquefaction. Despite various technological changes proposed and implemented since its inception, the Haber-Bosch process remains the predominant method for ammonia production. We first give a bird's eye view of current ammonia synthesis technologies available based on the latest trends, to justify why we think the conventional Haber-Bosch process is still a relevant technology worth investigation for further improvement. We review the engineering design modifications within the ammonia synthesis loop, examining improvements in the efficiency of ammonia synthesis. This review gives an overview of recent research and advancements focused on process intensification within the loop and its individual key components, i.e., the reactor and the catalyst, separation, and purge gas recovery technologies. It highlights significant progress and explores potential future directions in these areas.

哈伯-博什合成氨工艺的最新进展和改进
氨气至关重要,因为它是化肥生产中的关键氮源,可促进作物生长,同时由于氢含量高且易于液化,它还是一种新兴的能源载体。尽管哈伯-博什法自诞生以来提出并实施了各种技术变革,但它仍然是合成氨生产的主要方法。我们首先根据最新趋势鸟瞰了当前可用的氨合成技术,以说明为什么我们认为传统的哈伯-博什工艺仍然是值得进一步改进的相关技术。我们回顾了氨合成回路中的工程设计修改,研究了氨合成效率的提高。本综述概述了最近的研究和进展,重点是环路及其各个关键组件(即反应器和催化剂、分离和吹扫气体回收技术)内的工艺强化。它重点介绍了这些领域的重大进展,并探讨了未来的潜在发展方向。
