Abstract
Developing cost-effective and active catalysts that would replace noble metals is desirable for the ammonia decomposition reaction. Hence, this thesis focuses on the development and evaluation of a 10Ni/0.75TiO2-0.25CeO2 catalyst for ammonia decomposition, a promising route to carbon-free hydrogen production. The system parameters investigated include the effect of reaction temperature (550, 650, and 750°C) and the catalyst mass (100, 200, and 300 mg) on the performance of the ammonia decomposition process. The primary objective of this work is to investigate how catalyst composition and metal-support interactions influence activity, hydrogen production, and ammonia conversion. Catalysts were prepared by the incipient wetness impregnation (IWI) method and then calcined for the removal of volatile components and production of metal oxide. The results show that upon the inclusion of 10% of Ni to the pure support 0.75TiO2-0.25CeO2, the ammonia conversion increased from 19.14% to 53.46%. This study is the first to explore the potential of the 10Ni/0.75TiO2-CeO2 catalyst for ammonia decomposition and to assess the catalyst's ability to produce hydrogen.
