Abstract

In the following sections, the recent published studies on modeling andsimulation of monolith reactors were reviewed. Mass transfer, and reaction kineticswere achieved by establishing mass, energy and momentum balance equations. Themodel equations were solved simultaneously. Such a model can be useful for studyingthe impact of changes of superficial gas and liquid velocities on reaction rate withinthe slug flow regime. The reaction system used is the hydrogenation α–methyl styrene(AMS) to cumene over a palladium on γ–alumina catalyst, It is a well knownsystem used to understand three-phase reactor performance under mass transferlimited condition by the gas mass transfer through the liquid film at the catalystsurface to the active sites. The effects of superficial gas and liquid velocities onreaction rate were studied with the range of 10 cm/s ≤ UL ≤ 30 cm/s, and 10 cm/s≤ UG ≤ 30 cm/s. The flow pattern for all these range of velocities was in the Taylorflow pattern.
