Simplified Pressure Drop and Flow Distribution Modelling in Radial Catalytic Converters

A simplified model of a radial hydrocarbon reforming catalytic converter is presented. It focuses on fluid flow, distribution along the annular catalytic packed bed, and overall pressure drop. As for the chemistry aspect of the problem or possible issues due to pore blockages, these are not considered in the paper. The model is based on a set of several well-known equations such as the continuity equation, Euler's equation for inviscid flow, equation of state, etc. and is built with utilization in geometry optimization algorithms in mind. An optimization software implementing the discussed model and a comparison of results and experimental data related to a series of existing catalytic converters are presented as well.
