Abstract

Synthetic fuels provide a promising solution to storing renewable hydrogen in a safe and transportable manner. An aqueous solution of urea and ammonium nitrate could be used for such a purpose, providing a low carbon nitrogen-based option for energy storage. However, little is known of the chemical pathways leading to its thermal autoignition, nor of the effect diluent gases have on said pathways. In this study we provide details on the first simulation based investigation of this monofuel's thermal autoignition. The increase in the autoignition temperature with helium pressure was reproduced and validated against previous experimental results. The main reactions leading to the autoignition were identified using sensitivity analyses. The effect of diluent pressure on the main reaction pathways of the principal reactants and products is presented and discussed.
