Abstract
High-resolution thermogravimetry was used to study the thermodesorption of octane from ammonium nitrate (AN) prills with different porosities. The samples were wetted by immersion in octane. Multiple steps were obtained from the measured mass-loss curves, which reflect the evaporation of the excess liquid, as well as the thermodesorption of octane from the pores and the surface of the AN prills. The quantity of octane desorbed in these steps was correlated with the volume in the pores and the amount adsorbed on the surface, and used to estimate the adsorption capacity, porosity and surface area of AN prills. The results were also compared to observations from scanning electron microscopy.
