Abstract

Ammonia has been essential to human activities for centuries. It is widely used as feedstock for fertilizers, industrial chemicals, and emission after-treatment systems. Owing to its properties, ammonia has garnered interest as a carrier for hydrogen in energy applications. It can be generated from carbon-free emission sources and pyrolyzed to produce pure hydrogen for various applications. The combustion of ammonia for power generation has been previously reviewed in this journal besides several aspects of ammonia oxidation chemistry, as it relates to emission after-treatment and reburn systems. However, the pyrolysis and oxidation chemistry of ammonia requires further elucidation to improve its use as a hydrogen carrier and as a fuel for combustion systems. This article provides an in-depth review of ammonia pyrolysis and oxidation chemistry in noncatalytic and catalytic systems. The catalytic pyrolysis chemistry of ammonia to produce pure hydrogen is reviewed to understand catalyst and reactor requirements for scaling up this technology. The combustion properties of ammonia as a pure fuel and in mixtures, including ignition, flame propagation, and extinction characteristics; its pyrolysis and oxidation reactions; and its potential to produce pollutant emissions are extensively reviewed. Ammonia combustion reaction mechanisms are reported based on results from pyrolysis and oxidation reactors, shock tubes, rapid compression machines, and research engines. The experimental work is complemented by the development of detailed combustion models via chemical kinetic and quantum chemistry simulations. Herein, recent results on ammonia pyrolysis and oxidation chemistry are introduced and summarized by highlighting the pertinent aspects of this rich and rapidly increasing body of information.

氨热解和氧化化学
几个世纪以来,氨一直是人类活动的必需品。它被广泛用作化肥、工业化学品和排放后处理系统的原料。由于其特性,氨在能源应用中作为氢的载体引起了人们的兴趣。氨可从无碳排放源产生,并通过热解产生纯氢,可用于各种应用。除了氨氧化化学的几个方面外,本期刊还对氨燃烧发电进行了综述,因为这与排放后处理和回燃系统有关。然而,氨的热解和氧化化学需要进一步阐明,以改善其作为氢载体和燃烧系统燃料的用途。本文深入评述了非催化和催化系统中的氨热解和氧化化学反应。文章回顾了氨催化热解产生纯氢的化学过程,以了解扩大该技术规模所需的催化剂和反应器。还广泛综述了氨作为纯燃料和混合物的燃烧特性,包括点火、火焰传播和熄灭特性;氨的热解和氧化反应;以及氨产生污染物排放的潜力。根据热解和氧化反应器、冲击管、快速压缩机和研究发动机的结果,报告了氨的燃烧反应机理。通过化学动力学和量子化学模拟建立的详细燃烧模型对实验工作进行了补充。本文介绍并总结了氨热解和氧化化学方面的最新成果,着重强调了这些丰富且快速增长的信息的相关方面。

期刊介绍: Progress in Energy and Combustion Science (PECS) publishes review articles covering all aspects of energy and combustion science. These articles offer a comprehensive, in-depth overview, evaluation, and discussion of specific topics. Given the importance of climate change and energy conservation, efficient combustion of fossil fuels and the development of sustainable energy systems are emphasized. Environmental protection requires limiting pollutants, including greenhouse gases, emitted from combustion and other energy-intensive systems. Additionally, combustion plays a vital role in process technology and materials science. PECS features articles authored by internationally recognized experts in combustion, flames, fuel science and technology, and sustainable energy solutions. Each volume includes specially commissioned review articles providing orderly and concise surveys and scientific discussions on various aspects of combustion and energy. While not overly lengthy, these articles allow authors to thoroughly and comprehensively explore their subjects. They serve as valuable resources for researchers seeking knowledge beyond their own fields and for students and engineers in government and industrial research seeking comprehensive reviews and practical solutions.
