A model for fluorine atom recombination on a nickel surface

A detailed steady-state model for fluorine atom recombination on a nickel catalytic surface was developed based on the Langmuir-Rideal heterogeneous reaction mechanism. The model was compared to fluorine wall recombination data for a dilute mixture of atomic and diatomic fluorine in an inert diluent. The mixture flowed in a nickel tube. The model is able to duplicate the character of the data and to predict fluorine recombination coefficients as a function of temperature and other influencing conditions.
