Abstract

Abstract

The reaction thermodynamics, kinetics analysis and demonstration test of a high temperature oxidation reaction under complex irradiated AlN system was carried out by thermodynamic calculation software (HSC). The results show that it is necessary to ensure sufficient O₂ during the reaction to improve the yield of ¹⁴CO₂. The reaction rate is controlled by the diffusion of O₂ adsorption and ¹⁴CO₂desorption. To improve the reaction rate, the process should be improved from the aspects of reactor selection, contact mode, contact time and reaction temperature of gas-solid reactants. It provides important technical support for batch preparation of high specific activity Ba¹⁴CO₃.
