Monolithic Reactor

Model ID: 66


This model simulates the catalytic abatement of a volatile organic compound (VOC), in this case a contaminant in a waste gas. An analytical expression describes the velocity profile in the free channel, while reaction occurs in the washcoat that makes up the tubular shape of the free channel.

For simple geometries, the reactor can be described by a 2D model using time as the axial direction (or z-axis). This can be done if it is assumed that no significant change occurs in the transport properties in the axial direction. This means that the velocity profile is constant, and that diffusion in the axial direction is negligible.

This model was performed using the Chemical Engineering Module's pseudo application modes. This allow for good computational memory conservation as the model is performed in 2D with a time-stepping algorithm simulating the third dimension.
