Kinetic Model of Gas-Liquid-Liquid Reactive Extraction for Production of Hydrogen Peroxide

The kinetic aspects of the gas-liquid-liquid reactive extraction process for the production of hydrogen peroxide were investigated in a batch reactor. It was observed that the gas-liquid reaction rate is strongly affected by mass transfer of oxygen across the liquid film and the reaction can be simplified to pseudo-first order. The extraction rate is governed by both reaction and liquid-liquid mass transfer, and is slightly lower than the reaction rate. In addition, a kinetic model of the reactive extraction process for the production of hydrogen peroxide was developed. Kinetic parameters under different conditions were determined by experiments. The data calculated from the kinetic model match experimental data well under different conditions for hydrogen peroxide production in gas-liquid-liquid reactive extraction.
