Kinetic study of zinc oxide reduction by methane
Zinc oxide reduction by methane can be an alternative method for zinc production. Methane is more reactive than coke (the common reducing agent), thus, the operating temperature can be considerably decreased. Therefore, this method can omit or simplify the troublesome splash zinc condenser of the usual processes. Moreover, the gaseous products of this method can be used as synthesis gas for the petrochemical industries. In this work, the kinetics of zinc oxide reduction with methane was studied by thermogravimetry, and simultaneous and online gas analysis. Then by applying a suitable model, kinetic parameters were determined. These parameters are essential for the design of pilot or industrial plants.
