Ammonia decomposition is a promising process for on-site hydrogen production. In this article, the decomposition of ammonia is discussed experimentally and numerically, and alternative methods for providing the necessary energy for decomposition and the catalysts used for ammonia decomposition are described. The effect of the promoters used is analyzed in detail and the obtained catalytic activity is compared. Analysis ofthe reaction kinetics obtained with different catalysts is also presented and discussed. Finally, the structure ofthereactrsis reviewed andthe latestmicroractor technology for the decomposition of pure NH۳ is presented. Also, this paper presents the dominantchallenges that various reactor technologies still need to address for possible market entry and subsequent commercialization.
