Abstract: In order to improve the utilization rate of bromine trifluoride (BrF₃) in the gasification reaction of fluoroacyl sediment in the rotating cylinder, the static limit reaction experiment, working condition optimization experiment and multi-stage recycling process experiment were carried out. The results of static limit experiments show that BrF₃ can completely react with the sediment, and the chemical reaction rate is proportional to the pressure of BrF₃, and the reaction order of the chemical reaction kinetic equation between the sediment and BrF₃ is greater than 1. By improving the working conditions of the rotating cylinder, the stagnation mass and cylinder temperature of BrF₃ can increase, and the utilization rate of BrF₃ can be improved. Through the optimization of working conditions, the primary utilization rate of BrF₃ increases from 3.75% to 9.20%. By adopting the multi-stage recycling process, the utilization rate of BrF3 increases to 78.57%, and the industrial application economy is greatly improved after using gasification reaction technology.
