Work was performed at: Oklahoma State University and the University of Oklahoma

 

Scientific Achievement

An algorithm for the modeling of biphasic catalytic reactors, where simultaneous chemical reaction and phase distribution occurs, was implemented and validated using the hydrogenation of p-hydroxybenzaldehyde as a prototype reaction.

Significance and Impact

Phase behavior modeling and process simulation can be utilized to predict compositional dynamics and reduce the dependency on experimental data in the design and scale-up of biphasic reactors .

Research Details

  • The heterogeneous reaction was modeled using a Langmuir-Hinshelwood isotherm while assuming the surface reaction as the limiting step.
  • The Non-Random Two-Liquid (NRTL) thermodynamic model was used to represent the phase distribution.
