| In this work, the engineering and kinetic quantification of a novel potassium ferrate synthesis method are developed, in which potassium ferrate is produced as a solid using solid phase reactants inside a ball mill reactor.Potassium ferrate was produced at different experimental conditions (i.e. time, temperature, and relative amounts of reactants). Concentration of the produced potassium ferrate vs. time data at different temperatures shows that lower temperature favors potassium ferrate selectivity. Results show that short reaction time, 15.108% ice ratio, and reaction temperature (-5.5°C) to result in the highest concentration of potassium ferrate, for the conditions studied. A kinetic model that combines a traditional solid state kinetic analysis with a probability term that accounts for particle/particle interactions and attrition due to agitation was developed. The developed model was used to fit the experimental data for temperature of -5.5°C, 2.5°C and 10°C. The model fit was best for experimental data at -5.5°C which is likely because at this low temperature water is a solid and dissolution and decomposition are at minimum. |
