Catalytic Wet Oxidation: Mathematical Modeling of Multicompound Destruction
A mathematical model of a three‐phase catalytic reactor, CatReac, was developed for analysis and optimization of a catalytic oxidation reactor that is used in the International Space Station potable water processor. The packed‐bed catalytic reactor, known as the volatile reactor assembly (VRA), is operated as a three‐phase reactor and contains a proprietary catalyst, a pure‐oxygen gas phase, and the contaminated water. The contaminated water being fed to the VRA primarily consists of acetic acid, acetone, ethanol, 1‐propanol, 2‐propanol, and propionic acid ranging in concentration from 1 to 10 mg/L. The Langmuir‐Hinshelwood Hougen‐Watson (L‐H) (Hougen, 1943) expression was used to describe the surface reaction rate for these compounds. Single and multicompound short‐column experiments were used to determine the L‐H rate parameters and calibrate the model. The model was able to predict steady‐state multicomponent effluent profiles for short and full‐scale reactor experiments.
