Experimental results on gasification behaviors of freely‐falling spent alkylation sulfuric acid droplets in high‐temperature environments are presented, as well as baseline data on evaporation of water droplets and sulfuric acid droplets. Low evaporation constants have been measured for sulfuric acid droplets and spent acid droplets (relative to water droplets). Shape distortions and fragmentation (microexplosions) of spent acid droplets were also observed, and it has been found that initial droplet diameters are important in determining onset times and intensities of microexplosive behaviors. Simplified theory is developed, which suggests that the droplet distortion and fragmentation behaviors may be a result of SO 2 bubble formation inside the droplets.
