| Abstract Scope |
Molten salts have gained research attention as potential materials for ammonia synthesis. However, the alkaline species, such as nitride ions and hydride ions, dissolved in the molten salt pose challenges for this process. For instance, these alkaline species in the molten LiCl-KCl salt absorb the ammonia and thereby limit its yield. In addition, the alkaline nitride ions react with the alumina components in the reactor, causing corrosion. In this presentation, I will discuss on the mechanism involved and the strategies for addressing these issues. The ammonia release from molten salts fed with different proton sources have been investigated. Among these, the hydrochloric acid gas effectively reacts with the alkaline ions, enhancing ammonia yield. In summary, this work elucidates the interaction between proton sources and alkaline species in molten chloride salts, and also reports a new ammonia-synthesis process compromising molten salt electrolysis, nitrogen fixation, and hydrochloric acid introduction. |
