KINETIC STUDY OF OXIDATION OF ZINC SULFIDE PELLETS

Abstract

Pelleted spheres of zinc sulflde were oxidized in an air stream within a temperature range of 560°C-970°C. The reaction rate at zero time where no ash layer builds up was correlated as
k_s=3.66×10⁷ exp (-3.48×10⁴/ℜT)
The control regime of the reaction rate was found to be a function of temperature, and the predicted reaction rates were in reasonable agreement with experimental data.
