Abstract

Kinetic studies of the oxidation of zinc sulfide were carried out in a fluidized bed reactor over a temperature range of 740° to 1000°C with O-N gas mixtures of 20 to 40 pct O2. A mathematical model was developed to describe the overall conversion of the solids. Application of the model to the experimental data indicated that the chemical reaction at the outer boundary of the unreacted sulfide core was the rate-limiting step for the process. The temperature dependence of the kinetic constant corresponded to an activation energy of 40,250 cal per mole. Oxygen starvation in the bed was not limiting in any of the experimental runs, but an increase in the inlet-oxygen mole fraction resulted in a substantial increase in reaction rate.
